Answer:
x = 3
Step-by-step explanation:
Given
15x - 3(3x + 4) = 6 ← distribute and simplify left side
15x - 9x - 12 = 6
6x - 12 = 6 ( add 12 to both sides )
6x = 18 ( divide both sides by 6 )
x = 3
Answer:
C. a = 6
Step-by-step explanation:
Use the Pythagorean theorem

+ 64 = 100
= 36
a = 6
Answer:
<em>The average rate of change is $25.5 per hour, option B.</em>
Step-by-step explanation:
<u>Average Rate of Change
</u>
When we are explicitly given some function C(x), we sometimes need to know the rate of change of C when x goes from
to
. It can be computed as the slope of a line
.

The provided function is

We are required to compute the average rate of change between the points

Let's compute




The average rate of change is $25.5 per hour, option B.
Answer:
Rope jumping, slow pace, < 100 skips/min, 2 foot skip, rhythm bounce 8.8 630
Rope jumping, moderate pace, 100-120 skips/min, general, 2 foot skip, plain bounce 11.8 845
Rope skipping, general 12.3 881
Rope jumping, fast pace, 120-160 skips/min 12.3 881
Step-by-step explanation:
Answer:
ans: 31°
Step-by-step explanation:
<EFG = <EFH + <HFG
2x+52= 21 + ( x+31)
2x-x= 21 +31 -52
x= 0
so our question is to find <HFG so,
x+31°= 31°
