Question

When y= 55, x= 1/4. What is the value of y when x is 2.5?

Answer 1

Answer:

y = 550 when x = 2.5

Step-by-step explanation:

various ways to work this through: one simple way is to do cross method. arrange the numbers into fractions like this and then multiply the ones diagonal from each other

$\frac{55}{0.25} =\frac{y}{2.5}$

then multiply 55*2.5 together. multiply 0.25 and y together. Now you have this:

137.5 = 0.25y

solve for y and you get y = 550
