Answer:
Andy will spend 276y
Emily will spend 540y
Step-by-step explanation:
So for all intents and purposes, x=y
12 inches per 1 foot
3 feet per one yard
Andy:
23ft. needed
12*23=276
Will by 276 inches or 276x
Emily
15yards needed
15*3*12=540
Will by 540 inches or 276x
First, you would add 15/8 + 2/5 = 2 11/40
75/40 + 16/40 = 91/40
Simplify: 2 11/40
Next, you add 2 11/40 + (-7/8) = 1 2/5
2 11/40 - 7/8 = 2 + 11/40 - 7/8
LCD = 40
11/40 - 35/40 - 24/10
-24/10 = - 3/5
Simplify: 2 -3/5 = 1 2/5
Your final answer is 1 2/5
Hope this helped!
Good luck!
