Answer:
<u>x = 58</u>
Step-by-step explanation:
180 - 148 = 32
32 + 90 + x = 180
122 + x = 180
180 - 122 = x
x = 58

Answer:
$0.10/oz
Step-by-step explanation:
Unit rate simply means the amount per 1 unit of something.
In this case, we want to find the amount of money for 1 oz of something.
So, we divide 1.99 by 30 and divide 30 by 30 to get:
(1.99 / 30) / (30 / 30) = $0.0663 / 1 oz
Rounded to the nearest tenth, 0.0663 is about 0.1.
Thus, the answer is $0.10/oz.
Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ - 10, 10 ], thus
f(b) = f(10) = 10² + 9(10) + 18 = 100 + 90 + 18 = 208
f(a) = f(- 10) = (- 10)² + 9(- 10) + 18 = 100 - 90 + 18 = 28, thus
average rate of change =
=
= 9
