7 0

Step-by-step explanation:

Add 5 to both sides to get 10x alone: 10x = 70
Divide both sides by ten to get x alone: x = 7
The final answer is x = 7.

Step-by-step explanation:

$10x - 5 = 65 \\ \\ \therefore \: 10x = 65 + 5 \\ \\ \therefore \: 10x = 70 \\ \\ \therefore \:x = \frac{70}{10} \\ \\ \huge \red{ \boxed{ \therefore \:x = 7}}$

-x - 9 $\geq 5$

You want to get x by itself.

First subtract 9 from both sides of the equation.

-x - 9 $\geq 5$
+9 +9

-x $\geq 14$

Then divide -1 on both sides.

-x/-1 $\geq 14/-1$

I'm pretty sure when you divide a negative number when solving inequalities, you switch the sign.

x $\leq 5$

Triangle ABC has angle measures as shown. What is the value of X? Show your calculations.

180-96= 84
That means 8x+12=84
84-12=72
That means 8x=72
72÷8=9
therefore X=9
