Solve the equation for n. show all work
1\4 (2n+2)=3/8n

n=-4

Step-by-step explanation:

1/4(2n+2)=3/8n

2/4n+2/4=3/8n

2/4n-3/8n=0-2/4

4/8n-3/8n=-2/4

1/8n=-1/2

n=(-1/2)/(1/8)

n=(-1/2)(8/1)

n=-8/2

simplify

n=-4

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

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
