144= -12(x+5)
(I’m solving for x)
Start by distributing:
-12(x+5) = (-12 * x) + (-12 * 5) = -12x - 60
144 = -12x - 60
Add 60 to both sides to start isolating your variable:
204 = -12x
Solve for x by dividing both sides by -12:
x = -17
Step-by-step explanation:
multiply -12 with x and 5, after you get the answer. subtract 60 on the left and right, after getting 84 divide it by -12 and the final answer will be -7
x square plus 3x minus 18 equal 0 by using quadratic formula
Answer:
Step-by-step explanation:
x^2 + 3x - 18 = 0
(x+6)(x-3)=0
x=-6 x=3
i had this on my book so i just wanted to help.
Final answer:
The quadratic equation x^2 + 3x - 18 = 0 can be solved using the quadratic formula, resulting in two solutions, x = 3 and x = -6.
Explanation:
To solve the quadratic equation x^2 + 3x - 18 = 0 using the quadratic formula, we must first identify the coefficients a, b, and c in the standard form ax2 + bx + c = 0. In our equation, a = 1, b = 3, and c = -18. Substituting these values into the quadratic formula gives us:
x = [-b ± √(b^2 - 4ac)] / (2a)
By substituting the values we have:
x = [-(3) ± √((3)^2 - 4(1)(-18))] / (2(1))
Which simplifies to:
x = [-3 ± √(9 + 72)] / 2
x = [-3 ± √(81)] / 2
x = [-3 ± 9] / 2
Therefore, we have two possible solutions for x:
x = (-3 + 9) / 2 = 3
x = (-3 - 9) / 2 = -6
So, the solutions to the equation x2 + 3x - 18 = 0 are x = 3 and x = -6.
ll the members of a construction crew work at the same pace. Six of them working together are able to pour foundation in 22 hours. a How many hours would this job take if the number of workers decreased by factor of 2?
Answer:
44 hours
Step-by-step explanation:
Decreasing the people by a factor of 2 means we have 3 people
The job takes 6* 22 = 132 people hours
When we decrease the people, it will take more hours
132 people hours = 3 people * t hours
Divide each side by 3
132/3 = 3t/3
44 = t
It will take 44 hours
Determine ‘a’ and ‘d’ for t7= 3 + 5x and t11= 3 + 23x (formula is tn= a + (n-1) x d)
(25 POINTS!!)
Final answer:
To determine 'a' and 'd' for tn = a + (n-1)x, substitute the values of 'n' and 't' into the equations and solve the system of equations.
Explanation:
To determine 'a' and 'd' for tn = a + (n-1)x, we need to find the values of 'a' and 'd' that satisfy both t7 = 3 + 5x and t11 = 3 + 23x.
Step 1: Set up two equations
t7 = 3 + 5x
t11 = 3 + 23x
Step 2: Use the formula tn = a + (n-1)x to substitute the values of 'n' and 't' in the equations.
a + 6d = 3 + 5x (equation 1)
a + 10d = 3 + 23x (equation 2)
Step 3: Solve the system of equations.
Subtract equation 1 from equation 2: (a + 10d) - (a + 6d) = (3 + 23x) - (3 + 5x)
Cancel out the 'a' terms and simplify the 'd' and 'x' terms: 4d = 18x
Divide both sides by 18: d = 4.5x
Substitute the value of 'd' in equation 1 to solve for 'a': a + 6(4.5x) = 3 + 5x
Expand and simplify the equation: a + 27x = 3 + 5x
Subtract 5x from both sides: a + 22x = 3
Subtract 22x from both sides: a = 3 - 22x
So, the values of 'a' and 'd' are a = 3 - 22x and d = 4.5x.
Enzel goes online to buy a graphing calculator. He finds a site that currently has a promotion of 15% off on all orders over $50. Enzel decides to buy his graphing calculator, with a price tag of $83, at this site because he knows that he will get the 15% discount when he checks out. Enzel pays 4.5% sales tax on the discounted price and pays a shipping fee of $6.35. What is the total of Enzel’s online purchase?
So firstly, we need to find the discounted price. Since this is going to be a decrease by percentage, we will be using this format:
(1 - p)m(p = percentage in decimal form and m = original price)In this case:
[tex]15\% = 0.15\\\\(1-0.15)*83\\0.85*83\\70.55[/tex]
Now that we have the discounted price, we must apply the 4.5% sales tax. Since this is going to be an increase by percentage, we will be using this format:
(1 + p)mIn this case:
[tex]4.5\%=0.045\\\\(1+0.045)*73.55\\1.045*70.55\\73.72[/tex]
Now we have the discounted price with the sales tax. Now all we have to do is add the shipping fee:
[tex]73.72+6.35=80.07[/tex]
AnswerThe total price of Enzel's purchase is $80.07.
Answer:
A) $80.07

According to the manufacturer, about 26% of sour candy in a package of Sandy's Sours are grape. What is the probability that the first grape candy chosen from the bag will be, at LEAST, the third candy chosen overall?
To find the probability that the first grape candy chosen from the bag will be, at least, the third candy chosen overall, you multiply the probability that a candy is not grape (0.74) by itself (since we're considering two independent events, both candies not being grape). The answer is 0.5476.
Explanation:The subject of this question is probability which is a branch of mathematics. You're looking to find the probability that the first grape candy drawn from a bag of Sandy's Sours will be, at least, the third candy chosen overall.
Given that 26% of the candies are grape, the probability that the first candy drawn is not grape is 1 - 0.26 = 0.74 (or 74%). Since we're looking for the first grape candy to be the third candy drawn or later, we need the first two candies to be not grape.
The probability that the first candy drawn is not grape is 0.74. Because each candy draw is an independent event (the result of one draw does not affect the results of any other draws), the probability that neither the first nor the second candy drawn is grape is 0.74 * 0.74 = 0.5476 (or 54.76%).

Jasmine practices the piano for 10 minutes on Monday. Every day she increases her practice time by 5. If she continues this pattern, how many minutes will she practice on the 7th day?
Answer:
40 minutes
Step-by-step explanation:
Day 1) Monday --> 10 min.
Day 2) Tuesday --> 15 min.
Day 3) Wednesday --> 20 min.
Day 4 )Thursday --> 25 min.
Day 5) Friday --> 30 min.
Day 6) Saturday --> 35 min.
Day 7) Sunday --> 40 min.
Using the formula for the nth term in an arithmetic sequence, we find that Jasmine will practice for 40 minutes on the 7th day.
Explanation:The problem can be solved by using arithmetic progression. The first term of this sequence is the amount of time Jasmine spent practicing on Monday, which is 10 minutes. The common difference is the amount of time she adds to her practice every day, which is 5 minutes. To find out how long she will practice on the 7th day, we can use the formula for the nth term in an arithmetic sequence: a + (n-1)d.
Plugging in our values, we find:
10 + (7-1)*5 = 10 + 30 = 40.
So, Jasmine will practice for 40 minutes on the 7th day.

Charlene sold 15 magazines subscriptions for the fundraiser. Mark sold 17 subscriptions and Paul sold 12. How many magazine subscriptions did they sell in all?
Let s represent subscriptions
Equation:______
They sold_____ subscriptions in all.
Charlene, Mark, and Paul sold a combined total of 44 magazine subscriptions for their fundraiser.
Explanation:In this problem, Charlene, Mark, and Paul collectively sold magazine subscriptions. We need to find the total number of subscriptions sold. We can do this using simple addition: Charlene sold 15 subscriptions, Mark sold 17 subscriptions, and Paul sold 12 subscriptions. Therefore, using s to represent total subscriptions, our equation would be: s = 15 (Charlene's sales) + 17 (Mark's sales) + 12 (Paul's sales). Summing the numbers, s = 44. Hence, they sold 44 subscriptions in total.

How much did she withdraw from her account?
A). $50.27
B). $29.71
C). $0.00
D). $19.61
Answer:
A). $50.27
Step-by-step explanation:
Add $39.99 and -$10.28 to get $50.27
Final answer:
Julie withdrew $50.27 from her account, which can be calculated by adding her previous balance of $39.99 to the absolute value of her negative current balance, $10.28.
Explanation:
The question asks to determine how much was withdrawn from Julie's bank account, given that her balance went from $39.99 to -$10.28. To do this, we subtract the current balance from the previous balance. So the calculation is $39.99 - (-$10.28).
First, subtracting a negative is the same as adding its absolute value, so the equation can be rewritten as $39.99 + $10.28.
When these two values are added together, we get a total of $50.27. This means that Julie withdrew $50.27 from her account.
Therefore, the correct answer is A). $50.27.
