What is the value of m in the equation 5m − 7 = 6m + 11? ((99) give me you number? maybe? ) 1) 18 2) 1 3) −18 4) −1

We want to isolate "m" on one side of the equation and have a number on the other side. Let's start by subtracting both sides by 5m

Now, let's subtract both sides by 11

We now have the value of m.

The next thing I'm going to do is a bit tedious, but you typically want to have the variable on the left side of the equation in the field of math. It's a good habit to develop now.

Thus, the answer is choice 3, -18. Let me know if you need any clarifications, thanks!

Step-by-step explanation:

multiply with negative sign throughout, and you get

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

m∠a is 90°

m∠b is 40°
