To solve this problem, we need to simplify.
4x = 3/7
x = 3/7 ÷ 4
x = 12/7
x = 1 5/
Hope this helps!
You add the like terms
-3n+2+5n-7
-3n+5 = 2n
2 -7 = -5
2n -5 Is the answer
2.86 gallons
Step-by-step explanation:
If 1/35 gallon of gas = 1 mile
To travel 100 miles,

Therefore, the car needs 2.86 gallons of gas to travel 100 miles
Answer:
The expression = -75
Step-by-step explanation:
Evaluate: Enter a number for each variable.
−x2+7(y+2)−1
x=
5
y=
-9
Evaluate for x=5,y=−9
−52+7(−9+2)−1
−52+7(−9+2)−1
=−75
