timama [110]

Answer:

By multiplying the run by the slope, we get the rise value

Step-by-step explanation:

Mathematically. we have

slope = rise/run

Now, given that we know the run and we have the value of the slope, how can we get the rise

To get the rise, we simply have to multiply the run by the value of the slope

Hence, multiplying the run by the value of the slope will give the value of the vertical distance which is the rise

Can someone help me<br> 7 + 2h = 3 + 4h
STALIN [3.7K]

h = 2

7 + 2h = 3 + 4h

You must isolate the variable to solve using the order of operations, or PEMDAS.

4 = 2h

Subtract 3 from both sides of the equation, and subtract 2h from both sides of the equation.

\frac{4}{2}  = h

Divide both sides of the equation by 2.

h = 2
