Ok, so first you have to combine like terms.
2+3x-1+4x=5x+1
1+7x=5x+1
-1+1+7x=5x+1-1
7x-5x=5x-5x+0
2x=0

Five little girls taken in couples weigh 129 pounds, 125 pounds, 124 pounds, 123 pounds, 122 pounds, 121 pounds, 120 pound, 118
alekssr [168]

The weight of each one of the five little girls if taken separately is 242.4 lb.

<h3>Weight of each girl when taken separately</h3>

The weight of each girl can be determined from the average weight of the girls.

Weight of each girl = (Total weight) / number of girls

W = (129 + 125 + 124 + 123 + 122 + 121 + 120 + 118 + 116 + 114)/5

W = 1,212/5

W = 242.4 lb

Thus, the weight of each one of the five little girls if taken separately is 242.4.

A Cube has a face area of 81 square centimeters. What is the volume of the cube?
SSSSS [86.1K]
Well, if one face has an area of 81 square centimeters, then that means that each side of the square is 9 centimeters. The formula to find volume is l^3, so 9^3 = 729. 
In short, your answer would just be 729 centimeters^3

Hope this helped!!!

The sum of the measures of the interior angles of a polygon is 540��. classify the polygon by the number of sides. pentagon quad
zheka24 [161]
540/180=3+2=5 sides
It's a pentagon
Formula the sum of angles divide by 180 cuz a triangle equals 180 degrees then add 2.
Check below
So a 5 sided polygon known as a pentagon you subtract two. And it gives you 3 cuz it has 3 triangles in the pentagon that you can draw then 3 triangles times 180 = 540 degrees

In a recent year, U.S. advertisers spent $60 billion on television advertising. This number made up 40 percent of total advertis
schepotkina [342]

Answer:

The amount spent on all other types of advertising is $90 billion

Step-by-step explanation:

In this question, we are asked to calculate the amount spent on all other forms of advertising given the amount spent on tv advertising and the percentage of the total that it represents.

Firstly, we need to calculate the total amount spent on advertising.

we do not know this amount, so we can call it x.

Now, mathematically;

40% of x = $60 billion

40/100 * x = 60 billion

40x = 100 * 60 billion

x = (100 * 60)/40 = 6000/40 = 150 billion

The amount spent on all other advertising = Total amount spent on advertising- amount spent on television advertising = 150 billion - 60 billion = 90 billion
