An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:
Constant: A constant is a fixed numerical value.Variable: A variable is a symbol that doesn't have a fixed value.Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.Coefficient: A coefficient is a number that is multiplied by a variable in an expression.Given expression:
4b+7b+5
As. term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.
Terms are 4b, 7b, 5
Now, coefficient is a number that is multiplied by a variable in an expression.
coefficient are 4 , 7
As a constant is a fixed numerical value,
So, constant = 4, 7 , 5

Answer:
Ф Well all you need to do to write the linear equation for this function. I assume you want to know, is that you must obtain 2 points, and calculate the slope, then place the info within the following form.
Y = mx + b
1 of the points has to be the y intercept, which can be obtained from the graph, and the other, any other point, which can also be the X intercept.
So, X intercept - (2,0)
Y intercept - (0,3).
Slope = y/X = 3-0/0-2
Slope = 3/-2 or -3/2.
Now put everything together in form:
Y = mx + b
Y = -3/2x + 3.
I believe this is the solution.

lesson 7 homework practice convert measurment unit
The correct option is d. 8 oz. can of juice is most convenient to meet this requirement.
First, let's convert 240 milliliters to ounces because the answer choices are in ounces.
1 milliliter is approximately equal to 0.0338 ounces.
So, 240 milliliters is approximately \( 240 \times 0.0338 \) ounces, which is about 8.112 ounces.
Now, let's examine the options:
a. 5 oz. can of juice: Not enough juice. It's less than the required 8.112 ounces.
b. 4 oz. can of juice: Not enough juice. It's less than the required 8.112 ounces.
c. 12 oz. can of juice: More than enough juice. It's more than the required 8.112 ounces.
d. 8 oz. can of juice: Exactly the amount needed. It matches the required 8.112 ounces.
Since the resident is supposed to have 240 milliliters of juice every 2 hours, and 240 milliliters is approximately 8.112 ounces, the closest can size that would meet this requirement without being wasteful is an 8 oz. can. The 5 oz. and 4 oz. cans would not provide enough juice, and the 12 oz. can would provide more than necessary, potentially leading to waste or overconsumption. Therefore, the 8 oz. can is the most convenient and appropriate choice.
Members of the Blade runners skating club collected $950 from fundraising activities.They want to buy Altrablade skates, which are $48 a pair. How many pairs of skates can they buy? What does the remainder represent
Answer:
19 pairs
need 21% of $48 to buy 20th pair
Step-by-step explanation:
If the members collected $950 and they want to by Altrablade skates for $48 a pair, the amount of pairs of skates can be determine by dividing the total amount collected by the cost per skates:
[tex]950/48=19.79=19[/tex]
They can buy 19 pairs of skates by the remainder is 0.79. This represents the amount still needed to buy the 20th pair of skates. So they would need 21% of the $48 to buy a extra pair.

A filter in the shape of a cone has a diameter of 3 inches and a height of 4 inches.
How much liquid can the filter hold without it overflowing?
A) π in3
B) 3π in3
C) 12π in 3
D) 36π in3
Answer:
the correct answer in ''B''
Step-by-step explanation:
Final answer:
The cone-shaped filter with a diameter of 3 inches and a height of 4 inches can hold 3π inches³ of liquid without overflowing, which corresponds to choice B.
Explanation:
To find how much liquid can be held in a cone-shaped filter without overflowing, we use the formula for the volume of a cone, V = πr²h/3, where r is the radius, h is the height, and π (pi) is approximately 3.14. Given that the diameter of the cone is 3 inches, the radius (r) would be half of that, which is 1.5 inches. The height (h) is given as 4 inches. Plugging these values into the formula gives us:
V = π(1.5²)(4)/3 = π(2.25)(4)/3 = π(9)/3 = 3π inches³
Therefore, the cone-shaped filter can hold 3π inches³ of liquid without overflowing, which corresponds to choice B.
A car traveled 200 miles on 8 gallons of gas. Find the unit rate of gallons per mile.
Phil is riding his bike he writes 42 miles in 4 hours whats 52.5 miles in 5 hours and 63 miles and 6 hours find the constant of proportional and write an equation to describe the situation let X represent the #of hours.
Answer:
Step-by-step explanation:
The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.
d= 12.5 x t
To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:
For example
25miles÷2hours=12.5mileshour
A direct proportionality will always result in an equation that resembles this:
y=kx
where y and x are the related quantities and k is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. (And if the values given are real physical quantities, this constant will contain important information about the situation you are studying!)

Which ratio forms a proportion with 18/27?
A. 1/3
B. 2/5
C. 2/3
D. 7/9
Answer:
C. [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
The proportions are nothing but the equivalent ratios.
We are given the proportion = [tex]\frac{18}{27}[/tex]
We can reduce this proportion using the Greatest Common Factor (GCF).
The GCF of 18 and 27 is 9.
Therefore, dividing the numerator and the denominator by 9, we get
= [tex]\frac{18divide9}{27divide9}[/tex]
= [tex]\frac{2}{3}[/tex]
Therefore, the answer is C. [tex]\frac{2}{3}[/tex]
what is the answer to 38-19+12
To solve the expression 38-19+12, we subtract 19 from 38, resulting in 19, and then add 12 to get an answer of 31.
To solve the expression 38-19+12, we should follow the proper order of operations, which in this case, simply requires us to perform the subtraction and addition in the sequence they appear from left to right. First, subtract 19 from 38, then add 12 to the result.
Subtract 19 from 38, which equals 19 (38 - 19 = 19).
Add 12 to the result from step 1, which gives us 31 (19 + 12 = 31).
Therefore, the answer to the expression is 31.
