A recipe requires 2.5 teaspoons of sugar to make a candy bar. Which equation shows the number of teaspoons of sugar, y, needed to make x candy bars?
Please Help ASAP!

2.5x-y=0

Step-by-step explanation:

You will have to understand this question before solving

According to the question 2.5 teaspoon of sugar is required for making one candy

Then y teaspoon of sugar is required to make y candy

Let's start

2.5 sugar=1 candy

y sugar=x candy

Let's cross multiply

y=2.5×x

y=2.5x

Which can also be written as

2.5x-y=0

Therefore the final answer is 2.5x-y=0

Step-by-step explanation:

Number of teaspoons of sugar, y = 2.5 × x

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
