If a right triangle is 90° , the other acute triangle would be 10° because 90 - 80 = 10
3z = 2z + 5
3(5) = 2(5) + 5
15 = 15
answer
True

8-4x = 4x when x = 0
8 = 0 ....can't be
Answer
False
Answer:
d) V/(lh) = w
Step-by-step explanation:
The appropriate solution divides the equation by the coefficient of w, which is lh. In answer selection (d), that is done by first dividing by l, then by h.

<em>Comment on the solution</em>
One could just divide by l·h and be done with it.

To do this, for the first half you replace r with the number and solve the equation like that. For the second half, you reverse the equation, working back wards and doing the opposite function
