Solve the following equation for x.

9x - 4 = -49

a. -7
b. -10
c. -5
d -53/-9

C. -5

Step-by-step explanation:

First, add 4 to both sides

9x = -49 + 4

Simplify

-49 + 4 into -45

so 9x = -45

Dividing both sides w/ 9

x = 45/9

Finally, simplify 45/9 into 5

x = -5

Sorry for a late answer...I hope this helps

the f

last graph i believe

step-by-step explanation:

worked it out i believe

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
