Answer:
x = 10
Step-by-step explanation:
Step 1: Write equation
3x - 8 = 22
Step 2: Add 8 to both sides
3x = 30
Step 3: Divide both sides by 3
x = 10
Answer:
see below
Step-by-step explanation:
A percentage change is computed as follows:
percent change = ((new value) -(original value))/(original value) × 100%
For your first one, this looks like ...
percent change = ($25 -$75)/$75 × 100% = (-50/75) × 100% = -0.667×100%
percent change = -66.7%

When there are a lot of similar calculations to do, I like to use a spreadsheet. See below for the other percentage changes (rightmost column).
Answer:
the volume of the box increases 48 times compared to the 1st one.
Step-by-step explanation:
Volume of the box (1) = LWH
- length of a box is increased 4 time = 4L
- width is increased 4 times = 4W
- the height is tripled = 3H
=> The new volume of the box = 4L * 4W * 3H = 48LWH
So the volume of the box increases 48 times compared to the 1st one.
You'll need to isolate 9a on the left side of this equation
Please add 7 to both sides of the eqn, obtaining 9a = 117.
Solve for a by dividing both sides by 9: a = 117/9 = 13 (answer)
Answer:
child tickets - 47
adult tickets - 94
Explanation:
since the number of adult tickets sold is twice that of the number of child tickets sold, we can divide 141 into three parts to find the number of child tickets sold.
141 ÷ 3 = <u>47</u> (number of child tickets sold)
we can now multiply this by two to find the number of adult tickets sold.
47 × 2 = <u>94</u>
i hope this helps! :D
