-5(1 - 5x) + 5(-8x - 2) = -4x - 8
-5 + 25x - 40x - 10 = -4x - 8
25x - 40x + 4x = -8 + 10 + 5 = 7
-11x = 7
x = -7/11
Answer:
The first our to the second hour
Answer:
1. x = 1 over 2 or you can simplify by writing x = 0.5
2.x = -1 over 3 or x= -0.3
3.x = -17
4.x = 9
5.x = 7
6.-4 over 9 or x = -0.4
7.x = 1 over 10 or x = 0.1
8.x = 1 over 4 or x = 0.25
9.x = -1
10.x = 13
hope this helps! :-)
Answer:
Step-by-step explanation:
5/7 - 9/14 = (2 * 5)/(2 * 7) - (1 * 9)/(1 * 14) = 10/14 - 9/14 = (10 - 9)/14 = 1/14
What do you mean? At first it was 4 times as old, then it's twice her age?
