The solution is:

x= 4/3

y= 11/3.

Step by step: (substitution)

2x+1=-x+5

Add x to both sides.

3x+1=5.

Subtract 1.

3x=4.

Divide by 3.

x=4/3.

Use 4/3 instead of x to find y.

y=-(4/3)+5

y= 11/3.

Hope this helped!! :)

Answer:

1. C = $100 = .25(m)

2. C = $150

3. 800 = m

Step-by-step explanation:

1. C = $100 (flat fee rate) + .25m

2. c = $100 + .25(200 miles)

↓

c = $100 + 50

↓

c = 150

3. 300 = 100 + .25(m)

-100 -100 (subtract on both sides)

--------------------------------

200 = .25(m)

------------------- (divide by .25 to get m by itself)

.25

Therefore being 800 = m

Step-by-step explanation:

Given:

∠1 + ∠2 = 90°

∠1 = 45°

∠2 = 3x°

Find:

Solution:

Using the given values in the given equation, we have ...

45° +3x° = 90°

15 + x = 30 . . . . . . divide by 3°

x = 15 . . . . . . . . . . . subtract 15
