Answer:
it is 13x=2
Step-by-step explanation:
i ran the math through my multipurpose calculator
Class ratio of girls to boys is 3:5
So there are 3 girls and 5 boys in 8 students
If there are 32 students, then 3/(3+5) * 32 = 12 girls, and 5/(3+5) * 32 = 20 boys
Hope it helps you?
Answer:
g = -32
Step-by-step explanation:
3 = g/-4 - 5
Multiply both sides of the equation by -4
-12 = g + 20
Swap sides so that the variable terms are on the left hand side
g + 20 = -12
Subtract 20 from both sides
g = -12 - 20
Subtract 20 from -12 to get -32
g = -32
150 * 8 = $1,200
150 / 2 = $75
$1,200 + $75 = 1275
The area is found by multiplying the length by the width.
The original area = 60 x 40 = 2,400 square feet
He wants to make it 1/2 that size, so the new size would be 2,400 / 2 = 1,200 square feet.
To find the length divide the new area by the new width:
1,200 / 30 = 40
The new length should be 40 feet.
