The answer to 8 + 11 is 19
7.3 * 10^2= 730. Just move the decimal two laces to the right.
Answer:
18 units
Step-by-step explanation:
Manipulate the first equation to
y = 22-7z
Then substitute in the second to find z
8(22-7z) + 7z = 127
176-56z+7z = 127
-49z = -49
z = 1
So y = 22-7(1) = 22-7 = 15
y = 15; z = 1
