Answer:
23
Step-by-step explanation:
This equation can be derived from the question
let a represent the initial number Gus started with
{[(a x 8) - 12] / 4 } + 7 = 50
subtract 7 from both sides of the equation
[(a x 8) - 12] / 4 } = 43
Multiply both sides of the equation by 4
(a x 8) - 12] = 172
Add 12 to both sides
8a =184
Divide both sides by 8
a = 23.
You have to set up a system of equations
x+y=104
3x-y=104
Sodas = 78
Hotdogs = 26
Hi,
The answer is 4 sq. . cm,
If you see closely, it is nine times smaller, so we divide 36/9=4
So the area of the smaller figure is 4 sq. cm.
Hope this helps you.
Answer:
-6
Step-by-step explanation:
7x + 9 = 5x -3
-5x -5x
2x+9=-3
-9 -9
2x=-12
divide by 2
x = -6
Times the second equation by 2 to get y=9x-33 and then subtract
