Answer :
Step by Step Explanation :
1. 6x - 30 - 4x = 12x - 15
2. 2x - 30 = 12x - 15
3. -10x - 30 = -15
4. -10x = 15
5. x = -10/15
6. x = -2/3 (simplified)
1) we calculate the volume of the first carton:
volume=length x width x height
volume=3 ft * 2 ft * 2 ft=12 ft³
Therefore:
A machine can fill 12 ft³ in 3 seconds.
2) we calculate the volume of the second carton.
volume=length x width x heigth
volume=4 ft * 5 ft * 6 ft=120 ft³
3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.
12 ft³---------------------3 seconds
120 ft³-------------------- x
x=(120 ft³ * 3 seconds) / 12 ft³=30 seconds.
answer: 30 seconds.
What is the slope of the line segment XY?
For this one the answer is -2 so the answer is A.
Which of the following statements best describes the amount of water in the pool?
The answer is A
Hope this helps!
Answer:
a = 33
Step-by-step explanation:
IN a parallelogram consecutive angles are supplementary, thus
5a - 52 + 5a - 98 = 180, that is
10a - 150 = 180 ( add 150 to both sides )
10a = 330 ( divide both sides by 10 )
a = 33
Solutions
⇒ Given
Salary - $ 20
Spends - $ 14
The first step is to subtract 14 from 20. When we do this, we will know how much he saves.

Calculations
20 - 14 = 6
He saves $ 6 each week.
Now we have to find how many times 6 goes into 300. To do this we have to divide.
300 ÷ 6 = 50
<span>It is going to take him 50 weeks. </span>
