The correct answer is B. 83
Answer:
2,125m
Step-by-step explanation:
85% = 85/100
85/100 = x/2500m
Solve by cross multiplying
85(2500) = 100(x)
212,500 = 100x
Divide by 100 on both sides
x = 2,125m
Hope this helps :)
Add 3 on both sides of the equation
3x=0
divide 3 on both sides of the equation
x=0
Well you can't actually find a number, but you can make an equation.
lets call the bag of candy x, and the number of students in the teachers class S.
she gives every student in her class 4 pieces, so to find that amount, we have to multiply the number of students in her class by 4, the pieces of candy. 4S
afterwards she has 48 pieces, which is the endpoint, x is the starting point because that's the amount of candy the teacher started with.
so your equation is x-4S=48, but the thing is, the question is looking for the amount of students she gave candy to, so we have to isolate S, or in easier words; put S on one side, and the numbers on the other.
so the equation is S=1/4x-12
1.25/20=1x
1.25x=20
x=20/1.25=16
1 inch=16 feet
