Answer:

c = 15

Step-by-step explanation:

The angles are4 a linear pair and are supplementary, so the sum of their measures is 180 deg.

7c - 7 + 6c - 8 = 180

13c - 15 = 180

13c = 195

c = 15

The answer should be 15.

Explanation:
The line equates to 180, so you would put both equations (7c-7 , 6c-8) together and equal it to 180°.
So, it would come out looking like this:
7c-7+6c-8=180.

You’d add 7c and 6c to get 13c, and then subtract -8 from -7 (-7-8) to get -15.
The equation would now look like this.
13c-15= 180.

You’d add 15 to 180 to get 195. Then, you’d divide 195 by 13 to get 15, which would mean c=15.

Answer:

a.0       b. 33.5

Step-by-step explanation:

absolute value means everything turns positive.

5-6=-1 +1=0

b. 2(16.75)= 33.5.

everything inside the bracket turns positive.

For part A
|5-6+1|

You either calculate the sum or difference to this equation and would turn out to be 0 as your answer

|5-6+1|=0

Therefore 0 is the answer to |5-6+1| for part A

For part B
2|-16.75|
The absolute value of any number is always positive

2*16.75

You then multiply it and then come up with 33.5


Therefore 33.5 is the answer for 2|-16.75| in part B.

2|-16.75|

At a local ballpark a team charges $10 per ticket the team must pay its players $4000 it costs the owner $6 for each souvenir they gave away how many tickets must be sold to break even

Answers

Answer:400

Step-by-step explanation:it didn’t say it gives away and souvenirs so the 6$ can be out the equation and 4000 divided by 10 is 400

The number of tickets that must be sold to break even is 1000 if at a local ballpark a team charges $10 per ticket the team must pay its players $4000.

What is linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is:

At a local ballpark, a team charges $10 per ticket. The team must pay its players $4000. It costs the owners $6 for each souvenir they give away.

How many tickets must be sold to break even.

Let x be the number of tickets.

Let y be the total cost

From the data given in the question we can frame the linear equation in two variables:

y = 6x + 4000

y = 10x

After solving the above two linear equations in two variables.

6x + 4000 = 10x

10x - 6x = 4000

4x = 4000

x = 1000

Thus, the number of tickets that must be sold to break even is 1000 if at a local ballpark a team charges $10 per ticket the team must pay its players $4000.

Answers

Answer/Step-by-step explanation:

Given:

m<6 = 40°

Required:

Measure of all the other numbered angles

Solution:

Since line a is parallel to line b, therefore:

✔️m<1 = 180° - m<6 (supplementary angles)

m<1 = 180° - 40° (substitution)

m<1 = 140°

✔️m<2 = m<6 (corresponding angles)

m<2 = 40° (substitution)

m<3 = 180° - m<6 (same side interior angles are supplementary)

m<3 = 180° - 40° (substitution)

m<3 = 140°

✔️m<4 = m<6 (alternate interior angle)

m<4 = 40°

✔️m<5 = 180° - m<6 (linear pair)

m<5 = 180° - 40°

m<5 = 140°

✔️m<7 = m<5 (vertical angles)

m<7 = 140°

✔️m<8 = m<6 (vertical angles)

m<8 = 40°
