Jan spends part of her year as a member of a gym. She then finds a better deal at another gym, so she cancels her membership wit

ivann1987 [24]

Answer:

Number of months spent in first gym = 9

Number of months spent in second gym = 3

Step-by-step explanation:

Let she spent x months in a year at first gym and y months in a year at second gym

Now, there are 12 months in one year

⇒ x + y = 12

y = 12 - x .......(1)

Now, total money she spent in one year = $825

⇒ 75·x + 50·y = 825 .........(2)

Putting value of y from equation (1) in equation (2)

75·x + 50·(12 - x) = 825

⇒ 75·x - 50·x + 600 = 825

⇒ 25·x = 225

⇒ x = 9

Now, putting this value of x in equation(1)

⇒ y = 12 - 9

⇒ y = 3

Hence, number of months spent in first gym = 9

And number of months spent in second gym = 3

The equation of a line is 5x − 3y = 6. Which is the y-intercept of the line?

oksian1 [2.3K]

Answer:

y - intercept. = 2.

Step-by-step explanation:

Given : The equation of a line is 5x − 3y = 6.

To find : Which is the y-intercept of the line.

Solution : We have given 5x − 3y = 6.

Equation of line y = mx +b

Where , m = slope , y intercept = b

Now we convert the 5x − 3y = 6 in line form y = mx +b

5x − 3y = 6

On subtracting both sides by 5x

-3x = - 5x + 6

On dividing both sides by - 3.

x = $\frac{5x}{3}+2$ .

We cans see m = $\frac{5}{3}$ , y - intercept. = 2.

Therefore, y - intercept. = 2.

Find the measure of 22.

Stella [2.4K]

Answer:

Step-by-step explanation:

Basically since we know one circle is 360 degrees we know that those for triangles top angle add up to 360. Since they are the same we can do 360/4 = 90.

Then we do 90/2 to get half of that which is why the correct answer is 45 degrees.
