Answer:
x+y=24 so we can say
x=24-y making 3x+5y=100 become
3(24-y)+5y=100
72-3y+5y=100
72+2y=100
2y=28
y=14, since x=24-y
x=10
So there are 10 3-point questions and 14 5-point questions.
MARK ME AS BRAINLIST PLZ I REALLY NEED IT
The equation is 2.50÷5=x
2.50÷5=.50
Mrs. Baker paid $2.50 for 5 pounds of bananas
If x=.50 per banana
Then to get the cost of 8 bananas, you would do 8×.50=$4.00
Mrs. Baker paid $4.00 for 8 pounds of bananas
Each banana costs .50 cents per pound
