Answer: x = 11

Step-by-step explanation:

same as the last question, set them as equal and solve. here's my work:

<em>5x - 1 = 4x + 10</em>

<em>5x - 1 (+ 1) = 4x + 10 (+ 1)</em>

<em>5x = 4x + 11</em>

<em>5x (- 4x) = 4x (- 4x) + 11</em>

x = 11

Can someone plz explain how to do this Algebra 1 A=1/2(a+b)h for h
Alex_Xolod [135]
<span>A=1/2(a+b)h for h.

First, you need to get rid of 1/2, so divide both sides by 1/2.
A/(1/2) = (a + b)h

You can simplify the </span>A/(1/2) by multiplying by the reciprocal of 1/2, so 2/1.

2A = (a + b)h

Now divide both sides by (a+b).

2A/(a+b) = h
