x = 59, y = 44

2x + 18 + x - 15 = 180
3x + 3 = 180
3x = 177
x = 59

x - 15 = y
59 - 15 = y
44 = y

Answer:

x = 59° , y = 44°

Step-by-step explanation:

See the attached image below ,

Since the whole angle is 180° we can write it like this ,

(2x + 18)° + (x - 15)° = 180°

2x + x + 18 - 15 = 180

3x +3 = 180

3x = 177

x = 177/3

x = 59°

and now for y,

y = (x - 15)°      CORRESPONDING ANGLES PROPERTY

y = x - 15

y = 59 - 15

y = 44°

A ski resorts offers private lessons to their customers. Big time ski mountain charges $5 per hour plus $50 insurance. Powder hills charges $10 per hour plus $30 insurance. How many hours would make the cost of lessons the same for each resort?

Answers

Answer:

4 hours      

Step-by-step explanation:

Big time ski mountain charges $5 per hour plus $50 insurance.

Powder hills charges $10 per hour plus $30 insurance.

Let the number of hours be x.

For big time ski mountain, it means the total cost of x hours of lesson is:

[tex]B=50+5(x)\\B=50+5x[/tex]

For powder hills , it means the total cost of x hours of lesson is:

[tex]P=30+10(x)\\P=30+10x\\[/tex]

We  need to equate both equations to find the time that the costs would be the same.

That is :

[tex]50+5x=30+10x[/tex]

Collect like terms:

[tex]10x-5=50-30\\5x=20[/tex]

Divide through by 5:

[tex]x=\frac{20}{5} \\x=4 hours[/tex]

It would take 4 hours for the cost of the lessons to be the same.

On his way to work this morning, Gabe stopped and bought a salad to eat for lunch. He paid for it with $9 from his wallet.
What integer represents the change in the amount of money in Gabe's wallet?

Answers

An integer is a whole number that can be positive, negative, or zero.

The integer that represents the change in the amount of money in Gabe's wallet is -9.

What is an integer?

An integer is a whole number that can be positive, negative, or zero.

We have,

Salad cost = $9

Let the total amount in the wallet = $M

Now the amount in the wallet = $M - $9

There will be $9 less in Gabe's wallet.

The change can be denoted by a negative integer -9 from the wallet.

Thus,

The integer that represents the change in the amount of money in Gabe's wallet is -9.

Solve number 3 please :)

Answers

Answer/Step-by-step explanation:

Function A has a rate of change of 10 and function B has a rate of change of 5, so function A has a greater rate of change.

y = mx + b

The slope also known as rate of change is represented as the variable m in y = mx + b. So whatever number replacing m is the rate of change. In this problem 10 is the slope or rate of change.

In a graph, rate of change is determined by the rate in which the output is increasing or decreasing compared to the increase or decrease of the input. In this graph for every 1x added 5y is decreased. So, the rate of change is 5.
