Answer:

a. the number of people at Friday's, Saturday's, and Sunday's performances combined.

Step-by-step explanation:

The reason this information is needed to solve this problem is because we are looking to find the number of people who attended Saturday's performance. Without any information on Saturday's performance, there is no way to solve the problem. We are given the number of people on Friday and Sunday's performance, but are not given a total amount of people on all performances.

Answer:

A) The number of people at Friday's, Saturday's, and Sunday's performances combined.

Step-by-step explanation:

We are looking for the amount of people who attended Saturday's performance, but only one of the answers contains anything about Saturday, which is A. All the information in the other 3 choices we already know, because we know the amount of people at both Friday and Saturday's performance, so we can do some simple math to figure it out.

Answer:

you want to flip the original coordinates and make them both negative so (x,y) would become (-y,-x) so in your problem here Q' would be (0,-7), R' would be (-5,-8), S' would be (-10,-7) and T' would be (-5,-2). Hope that helped :>

Write three equations whose solution is x=3.5

My name is Ann [436]

Answer:

1. 2x + 23 = 30

2. 3x + 19.5 = 30

3. (10x - 20)/ 5 = 3

Explanation:

Work backward:

1. 2x + 23 = 30

Start:

x = 3.5

Multiply the equation by 2:

2x = 2 (3.5)
2x = 7

Subtract 30 from both sides

2x - 30 = 7 - 30
2x - 30 = -23

Add 23 and 30 to both sides:

2x + 23 = 30

2. 3x + 19.5 = 30

Start:

x = 3.5

Add 6.5 to both sides:

x + 6.5 = 10

Multiply by 3:

3(x + 6.5) = 30

Distributive property:

3x + 19.5 = 30

3. (10x - 20)/ 5 = 3

Start:

x=3.5

Multiply by 10:

10x = 35

Subtract 20:

10x - 20 = 15

Divide by 5:

(10x - 20)/ 5 = 15/5

(10x - 20) / 5 = 3

Find mZ3 if mZ5 = 145º and mZ4 = 45°

trapecia [35]

9514 1404 393

Answer:

C. 100°

Step-by-step explanation:

The exterior angle is equal to the sum of the remote interior angles.

∠5 = ∠3 +∠4

145° = ∠3 +45° . . . . fill in the given values

100° = ∠3 . . . . . . subtract 45° from both sides
