Answer:
57 years old
Step-by-step explanation:
- 400 - 3x = 229
- 3x = 171
- x = 57
- 400 - 171 = 229
A. You divide 1 (infront of x) by 12 to get 12. You divide -6 by 12 to get -2 for the y intercept.
Answer:
Step-by-step explanation:
4n - 6m = - 2 Subtract 4n from both sides.
4n-4n - 6m = -2-4n
-6m = - 2 - 4n Divide by - 6
-6m/-6= -2/-6 -4n/-6 Do the division
m = 1/3 + 2n/3
The signs change because each term has 2 minus signs. 2 minus signs make a plus. Or both minus signs cancel.
Our first expression is equal to zero:
So we simply find the expression that is equal to zero.
The final answer is a.
