Answer:
x = 3 (see below)
Step-by-step explanation:
To solve for x, you need to isolate the variable to one side of the equation. To do that, you need to use reverse operations. For example, the reverse operation of subtraction is addition.
In this case, we have:
15 = 5x
5x is the same thing as 5 (x) or 5 times x. This means the reverse operation is division. So, we need to divide both sides of the equation by 5:
15 = 5x

5 5

3 = x
x = 3
Answer:
Step-by-step explanation:
1. x = 11.2
2. 13
3. 9
4. -7/15
5. 15b
6. -12x + 16
7. 4x + 4
8. 11x-10
9. 10a + 5
10. -x, 15, and 2b
Hope that helps, and good luck!
(2x - 5)° + 45° = 180°
2x° + (-5 + 45)° = 180°
2x° + 40° = 180°
2x° = 180° - 40°
2x° = 140°
x° = 140 ÷ 2
x° = <u>7</u><u>0</u><u>°</u>
So, the value of x is 70°

I can’t see the pic , im so sorry
or 12 * 12 = 144
or 12 * 12 * 12 = 1728
