Answer:
-6(x-2)=-7(x-3) = False x = 9
Step-by-step explanation:
Solve for x:
-6 (x - 2) = -7 (x - 3)
Expand out terms of the left hand side:
12 - 6 x = -7 (x - 3)
Expand out terms of the right hand side:
12 - 6 x = 21 - 7 x
Add 7 x to both sides:
7 x - 6 x + 12 = (7 x - 7 x) + 21
7 x - 7 x = 0:
7 x - 6 x + 12 = 21
7 x - 6 x = x:
x + 12 = 21
Subtract 12 from both sides:
x + (12 - 12) = 21 - 12
12 - 12 = 0:
x = 21 - 12
21 - 12 = 9:
Answer: x = 9
Answer:
7+2-5=f
Step-by-step explanation:
If he starts on the 7 floor, then he is seven above ground, and that would clarify as a positive number. He then goes up 2 floors, which means we would add 2 to the original number. Going down five would mean we would subtract, because he is getting closer to zero, which is ground level. <em>F</em> represents the floor he is on now.

Answer:
175.
Step-by-step explanation:
In this question, translate the words into the symbols. "84" is 84, "%" is 1/100, "what" is x, the unknown, "of" is *, "is" is =, and "175" is 175. Therefore the words can be translated into an equation given below:
84 * x / 100 = 147
84x = 14700
x = 175.
Therefore, 84% of 175 is 147!!!
