B=14H+2
B+H=122 so 14H+2+H=122 or 15H=120 or H=8 ft.
The head was 8 ft and the body 114 ft (do the difference 122-8).
The answer is 4508 guess I helped
Answer: 360g
120 --> 10
x ---> 30
120*30=10*x
3600= 10*x
x= 3600/10
x= 360
Matthew needs 360g of flour
Answer: SECOND OPTION
Step-by-step explanation:
Given the following equation:
You can follow these steps in order to find the values of "x" that makes the equation true:
1. Subtract from both sides of the equation:
2. Factor the equation. Find two numbers whose sum be -5 and whose product be -36. These are 4 and -9:
Then you get:
Checking:
TRUE
TRUE
Using the together rate, it is found that the time it would take the second pump, working alone, to fill the tank is:
B. 90 minutes
The <em>together rate</em> is the <u>sum of each separate rate</u>.
In this problem:
- The together rate is of 1/60.
- The first rate is of 1/150.
- The second rate is of 1/x.
Then:
Applying cross multiplication:
Hence, it would take 90 minutes for the second pump, working alone, to fill the tank.
