Answer: v = -4
Step-by-step explanation:
Simplifying
4v + -7 = 5 + 7v
Reorder the terms:
-7 + 4v = 5 + 7v
Solving
-7 + 4v = 5 + 7v
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Add '-7v' to each side of the equation.
-7 + 4v + -7v = 5 + 7v + -7v
Combine like terms: 4v + -7v = -3v
-7 + -3v = 5 + 7v + -7v
Combine like terms: 7v + -7v = 0
-7 + -3v = 5 + 0
-7 + -3v = 5
Add '7' to each side of the equation.
-7 + 7 + -3v = 5 + 7
Combine like terms: -7 + 7 = 0
0 + -3v = 5 + 7
-3v = 5 + 7
Combine like terms: 5 + 7 = 12
-3v = 12
Divide each side by '-3'.
v = -4
Simplifying
v = -4
Answer:
125
Step-by-step explanation:
First you have to add 2.4 + 1.75 to get the number of miles she hiked in the morning. Then you subtract the the answer of that from 6.5 miles. Then you have to find out the difference of the miles she hiked in the morning and the miles she hiked in the afternoon by subtracting the miles she hiked in the afternoon from the miles she hiked in the morning.
1.75 + 2.4
4.15
6.5 - 4.15
2.35
4.15 - 2.35
1.8 miles is the answer
