Answer:
=
* 2 + 
Step-by-step explanation:
lets start with what we know.
the recipe calls for 2
cups of yogurt. and Paolo doubles the recipe. so multiply the recipe for yogurt by 2
2
* 2 = 5 cups of yogurt.
the total of yogurt and oats is
and we know how much yogurt we have so we subtract that from the total of both.
- 5 = 
the oats after doubling were
cups so u divide it by 2
/ 2 =
before doubling
Answer:
It's irrational
Step-by-step explanation:
the square root of 27 is equal to:

We know that
is an irrational number (but a real number), so
is the same.
In case we need to prove that
is irrational, please leave a comment.
-4(x + 1) + 5 = 17
Distribute -4 inside the parentheses.
(-4x - 4) + 5 = 17
Combine like terms (-4 + 5).
-4x + 1 = 17
Subtract 1 from both sides.
-4x = 16
Divide both sides by -4.
x = -4
Answer:L=4 W=15
Step-by-step explanation:
P=2L+2W
38-8=30
If length is 8 less than twice the width and the perimeter is 38, then subtract 38-8 which is 30, then divide 30 by 2 to get 15.
P=2(4) +2(15)
P=38
