Are 4x and 15 + x equivalent expressions
Final answer:
The expressions 4x and 15 + x are not equivalent as they yield different results for the same value of x.
Explanation:
The expressions 4x and 15 + x are not equivalent. Equivalence between two expressions means that for any value of the variable(s) involved, the expressions yield the same result. To determine if these expressions are equivalent, you can compare them for different values of x. For instance, if x is 1, 4x yields 4, whereas 15 + x yields 16, which are not the same. Thus, we can say that the expressions 4x and 15 + x are not equivalent as they produce different results for the same values of x.
Anita's mother hosted a party. The table shows the costs. Use associative property to write two equivalent expressions that could be used to find the total amount spent. TABLE ITEM:cake COST: $12 ITEM: hot dogs and hamburgers COST:$24 ITEM:drinks COST: $6
Using the associative property of addition, two equivalent expressions to find the total cost are: (1) ($12 + $24) + $6 and (2) $12 + ($24 + $6). Both expressions will yield the same result due to the associative property.
The question involves using the associative property of addition to find equivalent expressions for the total cost of items bought for Anita's mother's party. The total costs given are for three items: cake ($12), hot dogs and hamburgers ($24), and drinks ($6). To demonstrate the associative property, we can group the costs in different ways before adding them.
The first expression could group the cost of the cake and hot dogs and hamburgers together, then add the cost of drinks: ($12 + $24) + $6.The second expression could group the cost of hot dogs and hamburgers and drinks together, then add the cost of the cake: $12 + ($24 + $6).Both expressions will yield the same total cost when calculated, which shows the associative property of addition in action.

If b equals 8 and h equals 6 what does bh/2 equal
Answer:
if b = 8
and h = 6
and if im understanding correctly it is asking B*H/2 that would be 8*6 which is 48 then divided by 2 would be 24
Step-by-step explanation:
Final answer:
Using the formula A = bh/2 for the area of a triangle, with b as 8 and h as 6, we find that the area A equals 24 square units.
Explanation:
To solve the given problem, we need to apply the formula for the area of a triangle, which is A = bh/2, where 'b' is the base of the triangle and 'h' is the height. Given that b equals 8 and h equals 6, we can substitute these values into the formula to find the area.
A = bh/2
A = (8)(6)/2
A = 48/2
A = 24
Therefore, the area of the triangle when b is 8 and h is 6 is 24 square units.

Dave ordered dinner for a party of 10 people. Three people ordered the $4.75 chicken dinner, two people ordered the $4.95 fish dinner, and five had the beef dinner at a cost of $6.75 each. what was the average cost of each dinner at Dave's party?
Answer:
The average cost of each dinner at Dave's party is $5.79.
Step-by-step explanation:
Given:
Dave ordered dinner for a party of 10 people.
Three people ordered the $4.75 chicken dinner, two people ordered the $4.95 fish dinner, and five had the beef dinner at a cost of $6.75 each.
Now, to find the average cost of each dinner at Dave's party.
So, we get the total amount for the dinner:
Three people ordered the $4.75 chicken dinner.
[tex]4.75\times 3=14.25[/tex]
Two people ordered the $4.95 fish dinner.
[tex]4.95\times 2=9.90[/tex]
Five had the beef dinner at a cost of $6.75.
[tex]6.75\times 5=33.75[/tex]
Total amount of dinner = [tex]14.25+9.90+33.75=\$57.90.[/tex]
Now, to get the average cost of each dinner of 10 people we divide the total amount of dinner by 10:
[tex]57.90\div 10[/tex]
[tex]=\$5.79.[/tex]
Therefore, the average cost of each dinner at Dave's party is $5.79.
Final answer:
To find the average cost per dinner at Dave's party, calculate the total cost of each type of dinner and sum them up to get the total cost. Then, divide the total cost by the number of guests to obtain the average cost. The average cost per dinner is $5.79.
Explanation:
To calculate the average cost of each dinner at Dave's party, first calculate the total cost of all dinners combined by multiplying the number of each type of dinner by its price and then adding up the totals:
Chicken dinner cost: 3 dinners × $4.75 = $14.25
Fish dinner cost: 2 dinners × $4.95 = $9.90
Beef dinner cost: 5 dinners × $6.75 = $33.75
Next, add all the costs together to get the total cost of the dinners:
Total cost = $14.25 + $9.90 + $33.75 = $57.90
Now, divide the total cost by the number of guests to find the average cost per dinner:
Average cost = Total cost ÷ number of guests
Average cost = $57.90 ÷ 10 = $5.79
So, the average cost per dinner at Dave's party is $5.79.
Twelve decreased by twice a number is the same as 8 times the sum of the number and 4. What is the number.
Answer: -2
Step-by-step explanation:
Let the number be x , then twice the number is 2x.
Twelve decreased by twice the number = 12 - ( 2x )
8 times the sum of the number and 4 = 8 ( x + 4 )
combining the two , we have
12 - 2x = 8 ( x + 4 )
12 - 2x = 8x + 32
12 - 32 = 8x + 2x
-20 = 10x
x = -20/10
x = -2

Suppose your parents invest $20,000 in an account paying 5% interest compounded annually. What will the balance be after 10 yr?
Answer:
$32,577.89
Step-by-step explanation:
Use the formula for amount after compound interest. A = P(1 + i)ⁿ
'P' is the principal, meaning starting amount. P = $20,000
'i' is the interest per compounding period in decimal form. Since the compounding period is annual, just like the interest rate is given as, i = 0.05. If the compounding period was not annual: then i = r/c (annual interest rate divided by number of compounding periods in a year).
'n' is the number of compounding periods, or the number of times the interest increases. n = 10. Calculate 'n' using n = tc (number of years times number of compounding periods in a year). Since c=1, n = t. ('t' is the number of years).
'A' is the amount after 'n' years. We need to find A.
Use all of the numbers that we know for the variables, replace the variables with the numbers in the formula. Solve for 'A'.
A = P(1 + i)ⁿ
A = $20,000(1 + 0.05)¹⁰ Add inside brackets first
A = $20,000(1.05)¹⁰ Do (1.05)¹⁰ then multiply by 20,000
A = $32,577.89 Answer
Therefore the balance will be $32,577.89 after 10 years.

Write an equation from the following points (plug in the numbers you would use for "m" and "b"):
(3, 9) and (6, 13)
Answer:
[tex]y =\fracc{4}{3}x+5[/tex]
m=4/3 and b=5
Step-by-step explanation:
We want to find the equation of the line passing through (3,9) and (6,13).
We determine the slope using:
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
Let:
[tex](x_1=3,y_1=9), (x_2=6,y_2=13)[/tex]
We substitute the points to get:
[tex]m = \frac{13 - 9}{6 - 3} = \frac{4}{3} [/tex]
We now use the formula:
[tex]y-y_1=m(x-x_1)[/tex]
We substitute to get:
[tex]y - 9 = \frac{4}{3} (x - 3)[/tex]
Multiply through by 3 to get;
[tex]3y - 27 = 4(x - 3)[/tex]
We expand further to get:
[tex]3y - 27 = 4x - 12[/tex]
This implies that:
[tex]4x - 3y = - 15[/tex]
We solve for y to get:
[tex]y =\fracc{4}{3}x+5[/tex]
Therefore m=4/3 and b=5

A fraction f multiplied by 4 equals 1/2
Answer:
f = 1/8
Step-by-step explanation:
f x 4 = 1/2
f = 1/8 ( multiplying both sides by 1/4 )

A new car is purchased for 24000 dollars. The value of the car depreciates at 6.75% per year. To the nearest year, how long will it be until the value of the car is 15500 dollars?
Final answer:
To the nearest year, it will take about 6 years for the value of the car to reach $15,500.
Explanation:
To find how long it will take for the value of a car to depreciate to $15,500, we can set up an equation using the formula for exponential decay: V = P[tex](1 - r)^t[/tex], where V is the final value, P is the initial value, r is the depreciation rate, and t is the time in years.
Plugging in the given values, we have 15500 = 24000[tex](1 - 0.0675)^t[/tex]. To solve for t, we can take the logarithm of both sides:
log(15500) = log(24000[tex](1 - 0.0675)^t)[/tex]
t * log(1 - 0.0675) = log(15500/24000)
t = log(15500/24000) / log(1 - 0.0675)
Using a calculator, we find that t is approximately 5.54 years. Rounding to the nearest year, it will take about 6 years for the value of the car to reach $15,500.
The equation v=-2000+20000 describes the value in dollars of a certain model of car after it is t years old. If a car is worth $10,000, substitute 10,000 into the equation to find the age of the car.
I'm assuming the equation is:
v = -2000t + 20,000 because the value of a car decreases with time
v = worth of the car
t = number of years
Since you know the value of v = 10,000, substitute or plug in 10,000 for v in order to find t
v = -2000t + 20,000 Substitute 10,000 into v [To find t, you need to get the variable by itself to one side of the equation.]
10,000 = -2000t + 20,000 Subtract 20,000 on both sides
-10,000 = -2000t Divide -2000 on both sides to get t by itself [negative divided by a negative results in a positive]
