25 Pts + Brainliest for the first correct answer.

WITCHER [35]

Answer:

25. x=19

26. 16=x

27 28=x

28. 24=x

Step-by-step explanation:

25. The two angles make a straight line (180 degrees)

6x-17 + 3x+26 = 180

Combine like terms

9x +9 = 180

Subtract 9 from each side

9x+9-9=180-9

9x = 171

Divide by 9

9x/9 = 171/9

x=19

26. These angles are corresponding angles and corresponding angles are equal if the lines are parallel

4x+20 = 6x-12

Subtract 4x from each side

4x-4x+20 = 6x-4x-12

20 =2x-12

Add 12 to each side

20+12 = 2x-12+12

32=2x

Divide by 2

32/2 = 2x/2

16=x

27 These are alternate interior angles and alternate interior angles are equal if the lines are parallel.

4x+30 = 6x-26

Subtract 4x from each side

4x-4x+30 = 6x-4x-26

30 = 2x-26

Add 26 to each side

30+26 =2x-26+26

56= 2x

Divide by 2

56/2 = 2x/2

28=x

28. These are corresponding angles and corresponding angles are equal if the lines are parallel.

99=3x+27

Subtract 27 from each side

99-27 = 3x+27-27

72 = 3x

Divide by 3

72/3 = 3x/3

24=x

Danny's truck has a fuel tank with a capacity of 20 gallons of gas. The truck averages 17 miles per gallon of gas. The function

Fittoniya [83]

For this case we have the following function:

$M (g) = 17g$

Where,

g: number of gallons of gas

M (g): number of miles that Danny's truck travels

We know that the maximum capacity is 20 gallons of gas.

Therefore, the maximum distance the truck can travel is given by:

$M (20) = 17 (20)$

$M (20) = 340$

Thus, the domain of the function is:

$0 \leq g \leq 20$

The range of the function is:

$0 \leq M(g) \leq 340$

Answer:

A domain and range that are reasonable for the function are:

D. D: 0 ≤ g ≤ 20

R: 0 ≤ M (g) ≤ 340
