find the measure of angle 8
​

Answers

Answer: 18

Step-by-step explanation:

First we need to solve for x to find the measure of the adjacent angle.

-6x+64 = 8x + 162

subtract 162 to leave x by itself

-6x- 98 = 8x

add 6x to both sides

-98 = 14x

now divide by 14

x = -7

Now solve one of the given equations to find the measure of the adjacent angle.

8(-7)+162

-56 + 162 = 106

Meaning the measure of angle 8 is 18

because they'll add up to 180(The measure of the line)

Answer:

measure of angle 8 is 16 6/7

Step-by-step explanation:

-6x+64=8x+62 because there is a transversal.

2=14x

x=2/14

so, now you have to find 8x+162. 163 1/7 degrees. (Plug in variables)

measure of the angle we just found + measure of angle 8 is 180 degrees.

(straight line definition) so 180-163 1/7= 16 6/7

measure of angle 8 is 16 6/7

Answers

Answer:

x = -4

y = -25

Step-by-step explanation:

Since one of the equations is already set with one variable as the subject ( y = 7x + 3) substitute that into the one below it:

9x - 2y = 14

9x - 2(7x + 3) = 14

9x - 14x - 6 = 14

-5x = 20

x = -4

Substitute this into one of the equations and solve for the other variable:

y = 7x + 3

y = 7(-4) + 3)

y = -28 + 3

y = -25

hope this helps!

Answer:

(- 4, - 25 )

Step-by-step explanation:

Given the 2 equations

y = 7x + 3 → (1)

9x - 2y = 14 → (2)

Substitute y = 7x + 3 into (2)

9x - 2(7x + 3) = 14 ← distribute and simplify left side

9x - 14x - 6 = 14

- 5x - 6 = 14 ( add 6 to both sides )

- 5x = 20 ( divide both sides by - 5 )

x = - 4

Substitute x = - 4 into (1) for corresponding value of y

y = 7(- 4) + 3 = - 28 + 3 = - 25

solution is (- 4, - 25 )

Rosa loves to run. She set a goal to run greater than 490 miles this year. To date, she has run 145 miles. If she begins to run 15 miles per week, how long will it take Rosa to reach her goal?
Write an inequality, using x as the variable, that represents this situation.

Answers

Answer:

Step-by-step explanation:

145+15x>490. subtract 145 from both sides

15x>345, divide both sides by 15

x>23

So she will need to run for more than 23 weeks to reach her goal.

Find the number of square inches in one square foot.
144
12
24

Answers

think of this as finding the area of a box. if each side of the box is one foot long, or 12 inches long, you need to multiply length times width to find the square inches. in this case it would look like:

A= 12in x 12in

12in x 12in = 144in^2

A = 144 in^2

therefore there are 144 square inches in one square foot.

Answer:

it is 144

Some systems of inequalities can have no solution.

Answers

Answer:

Yes, that is true.

Step-by-step explanation:

The bounded regions of the two inequalities do not overlap, so there is no solution set. However, the existence of parallel lines does not necessarily indicate that there is no solution, it just means that there is the possibility of no solutions.

Mr. Sanchez’s class sold fruit pies for $1.65 each and Mr. Kelly’s class sold bottles of fruit juice for $1.36 each. Together, the classes sold 79 items and earned $118.17 for their school.

(a) Write and solve a system of equations that model the problem. Show all your work.

(b) Which class earned more money?

(c) How much more money did that class earn?

Answers

Answer:

Step-by-step explanation:(a)

1.65p+1.36j=118.17 and p+j=79

We can say p=79-j and sub this value in first equation

1.65(79-j)+1.36j=118.17

130.35-1.65j+1.36j=118.17

-0.29=-12.18

j=42, p=79-j, p=79-42=37

(b)

1.65(37)=61.05 and 1.36(42)=57.12

Sanchez class earned more selling pies.

(c)

61.05-57.12=3.93

So Sanchez class made $3.93 more than Kelley class.
