Answer:
y=10
Step-by-step explanation:
(y-10)^2=0
Take the square root of each side
sqrt((y-10)^2)=sqrt(0)
y-10 =0
Add 10 to each side
y-10+10=0+10
y = 10
To complete the equation and tell which property you used.
(3×10)×8=___(10×8)
The property of basic operations that was used here is the:
1. Associative property of
multiplication where you can group or cluster certain values or numbers in an
equation and still yield the same product.
The missing value would be 3. Hence,
2. (3 × 10) × 8 = 3 (10 × 8)
Observe the parenthesis which has only moved from starting with three to
the value of ten.
