Answer: -1
Step-by-step explanation:
1-(-1^2)+(-1^3) = 1-1+(-1)= -1
Answer:
80km
Step-by-step explanation:
To solve this problem, we need to cross multiply. Lets input the values (1.2, 1.0, 96) as shown below:

Next we cross multiply. We multiply 1.2 and x, and we multiply 96 and 1.0.
1.2(x) = 1.2x
96 x 1.0 = 96
Now, lets put the values above back into the equation:
1.2x = 96
Lets solve this equation. First we divide 96 by 1.2.
1. 
2. 
This means that our answer is 80km.
Draw six dots then a plus sign then draw seven dots and the count them and put an equal sign and however many dots. Doe the same with the other numbers
X - Linda's speed
(x+8 )- Colleen's speed
8x - Linda's distance for 8 h
8(x+8) = 8x+64 - Colleen's distance for 8 h
8x + 8x + 64 = 176 - distance between Colleen and Linda after 8 h
8x + 8x + 64 = 176
16x +64 = 176
16x = 176 - 64
16x = 112
x= 7 mph Linda's speed
x+8 = 7+8 = 15 mph Colleen's speed
