To find the first blank, just replace x in the equation with 12 and solve.
a(12) = 50 - 1.25(12) = your answer for blank 1
For blank 2: because x represents the number of apps on her phone, and x is given 12 for this problem, she bought 12 apps.
For blank 3: You would mention how many apps she got twice, so not the first option or the third option. It should be the answer from the first blank because the equation represents how much money is in her account.
Answer:
The correct answer is fabric Jimmy's sister needs = 
× fabric Jimmy needs = × 
yards of fabric.
Step-by-step explanation:
Jimmy's costume requires ⅞ + ½ + 1 
yards of fabric = 
yards.
His sister's costume requires 3 x (⅞ + ½ + 1 ⅔) the amount of fabric that Jimmy needs = 3× (
) yards of what Jimmy needs = yards of what Jimmy needs.
The relationship between how much fabric Jimmy needs and how much fabric his sister needs is given by
Fabric Jimmy's sister needs = × fabric Jimmy needs = × yards of fabric.
It usually helps a person to get a better idea of how much or how big something is. I'm actually not sure why, but let's use an example. You got 38 out of 43 questions on a test. when you see 38/43 you don't really know how good that score is, but if you make it a percentage (Dividing the first number by the second to get the percentage) it's 88%. You know you did well on that test.
