2) 64
you can use the explanation below to help find the other 6 problems
Step-by-step explanation:
1) 4(5+6) - 15 = 4 * 11 - 15 = 44 - 15 = 29
2) 8(2+4) + 16 = 8 * 6 + 16 = 48 + 16 = 64
Answer:40 square yards
Step-by-step explanation:
Given
Floor area A=10 square yards
Red tile costs
per square yards
White tile costs
per square yards
Total money spent=
on tiles
Suppose red tiles cover an area of
square yards
So, we can write

Red tiles cover an area of 40 square yards
a is given to us so just plug a into the first equation:
b-3 - 3b =9
Add 3 to both sides:
b-3b=12
Combine like terms:
-2b=12
Divide by -2 to get b by itself:
b=-6
The only answer with b as -6 is the first one, (-9,-6)
