Answer: C: 2(n+5)
Step-by-step explanation:
16) First solve like a normal equation.
3|x/9| - 1 = 2
3|x/9| = 3
|x/9| = 1
Now just separate into two equations:
x/9 = 1
x/9 = -1
So x = 9, -9
17) Solve like normal:
-4 - 2|b - 10| = -6
-2 |b - 10| = -2
|b - 10| = 1
Now just separate into two equations:
b - 10 = 1
b - 10 = -1
So then b = 11, 9
The error is that 15 was subtracted on the left side when it should’ve been added.
Corrected equation:
27 = n-15
Add 15 to both sides
42 = n
Answer:
<h2>220</h2>
Step-by-step explanation:
bowling balls without holes = 77 and 35%
find: how many bowling balls in the store?
let x be the total
its a ratio and proportion:
<u> 77 </u> = <u> x </u>
35 100
cross multiply:
35 (x) = 77 (100)
x = 7700 / 35
x = 220 ------>> total number of balls in the store
Answer:
The volume of the prism is 300 cubic inches not 300 square inches
Step-by-step explanation:
we know that
The volume of the prism is equal to
where
B is the area of the base
h is the height of the prism
we have
substitute
therefore
The volume of the prism is 300 cubic inches not 300 square inches
