It’s 6 and idk what a tape diagram is so just do that
4(x+1)=y-8
4x+12=y
Distribute the 4 into x and 1 and then add 8 to the other side
Answer: 
Step-by-step explanation:
We can use the following formula to solve this exercise:
In this case "T" is the time in hours it takes to both taps fill the pool working together, "A" is the time in hours for the first tap filling the pool alone an "B" is the time in hours for the second tap filling the pool alone.
We can identify that:
Then, we must subsitute the known values into the formula:
And finally we must solve for "B".
Then we get:
The answer to the question is 12
Answer:
-3
Step-by-step explanation:
Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:
m =
y2 - y1
x2 - x1
