Answer:
Step-by-step explanation:
<u>What number</u> <u>divided by</u> <u>-7</u> <u>is equal to</u> <u>-15</u>
∨ ∨ ∨ ∨ ∨
x ÷ -7 = -15
Multiply -7 to both sides:
Alright,
you will need to solve for each variable to find if they got the equation correctly or not..
Let's start with h
isolate h
(1/2)h = A/(b1+b2)
Now we need to get rid of 1/2 we may do so by multiplying both sides by 2
h = 2(A/(b1+b2))
And that's not how they did it for h so Option D doesn't apply
Let's see C
Also doesn't apply since they multiplied 2 only by A rather than A/h
Let's see B
Also not correct they made the same mistake as with option C
Let's see A
again same mistake
when multiplying both sides by 2
the 2 should be as following
I believe you should contact your instructor and explain that non of the options is right.
