Solve for r.
You want to get r by itself on one side on the equal sign.
bh + hr = 25
Subtract bh from both sides.
hr = 25 - bh
Divide h on both sides.
r = 25 - bh / h
The two h's cancel each other out.
r = 25 - b
Hope this helps!
Answer:
B
Step-by-step explanation:
we are given a equation of a line
we want to figure out the equation of the perpendicular line passes through the <u>(</u><u>6</u><u>,</u><u>5</u><u>)</u><u> </u>points
in order to do so
recall that,
we got from our given equation that m=2
because equation of a line is y=mx+b
thus
remember that, when we want to figure out perpendicular line or parallel line we should the formula given by
since we got our perpendicular m is -½, and , substitute
to get the perpendicular equation you should simplify the above equation to y=mx+b form
distribute -½:
add 5 to both sides:
hence,
our answer choice is B
<u>Answer:</u>
<u>Step-by-step explanation:</u>
To find the solution to the equation, we have to rearrange the equation to make the subject:
⇒ [Subtracting 2 from both sides]
⇒
⇒ [Subtracting from each side]
⇒
⇒ [Diving both sides by 213]
⇒
