Answer:
2000 dollars
Step-by-step explanation:
let's say each boy gets x dollars
each girl gets 100 more dollars than each boy, or 100+x dollars
money = total money amongst boys = x dollars for each boy = 5 * x as there are 5 boys
money = total money amongst girls = 100 + x dollars for each girl = (100+x) * 4 as there are 4 girls
set the two equal to each other
5*x = (100+x) * 4
expand
5x = 400 + 4x
subtract 4x from both sides to put all the variable terms on one side
x = 400
each boy gets 400 dollars
total money = 5 *x = 2000 dollars
Answer:
$5x + $4y ≤ $120
let x = 10
y = 5
$70 ≤ 120
Step-by-step explanation:
Note that
> means greater than
< means less than
≥ means greater or equal to
≤ means less than or equal to
the total amount Shanley has is $120. She can spend less than this amount or the amount exactly. So, the inequality sign to be used is ≤
$5x + $4y ≤ $120
let x = 10
y = 5
(50) + 20 ≤ 120
$70 ≤ 120

A) 6
b) 10
Answer:
A. The area of a rectangle is equal to all the areas of the small rectangles. The dimensions of the small rectangles are 2a, 3a, and 4a. If you add those areas up, 2a+3a+4a equals the area of the large rectangle.
B. The area of a rectangle equals the width and height. The height of the large rectangle is already shown in the picture, a. The width is seperated into three portions, 2, 3, and 4. To find the total width, add 2+3+4. Now, multiply the width by the height to calculate the area. (2+3+4)a
7x + 10 = 13(12x - 3) + 14x
7x + 10 = 156x - 39 + 14x
10 + 39 = 156x - 7x + 14x
49 = 163x
x = 49/163
