Im assuming by 5-.8, you mean 5/8ths and by 1-.4, you mean 1/4th...
x=5/8+1/4
x=5/8+2/8
x=7/8
They ate 7/8 together
Just saying you have a 25% chance of getting it right if you guess
Answer:
6z + 9
Step-by-step explanation:
distribute 3/4 by 8z to get 6z
distribute 3/4 by 12 to get 9
Change 212,514 into 215,000.
Change 396,705 into 400,000.
--------
Estimate:
215,000 + 400,000 = 615,000
Therefore:
212,514 + 396,705 ≈ 615,000
20, you just need to substitute the x value in the equation
(-2)2-7(-2)+10=
=20
