Answer:
Step-by-step explanation:
-4 - 7 + 10x = -7 + 6x...combine like terms
10x - 11 = 6x - 7
10x - 6x = -7 + 11
4x = 4
x = 4/4
x = 1.........ONE SOLUTION
4^0 is 1 because any number to the zero power is one so 1*5=5
Answer:
28 miles
Step-by-step explanation:
Let w stand for the number of miles Derrick runs each week. Then after 4 weeks of training, he wants the total mileage to be 100 miles.
16 + 3w = 100
3w = 84 . . . . . . . subtract 16
w = 28 . . . . . . . . divide by 3
Derrick will run 28 miles each week to achieve his training goal.
Answer:
0
Step-by-step explanation:
Perimeter P=2L+2W
P=24
L=w+4
P=2(w+4)+2w
24=2w+8+2w
24=8+4w
16=4w
w=4
L=8
