Answers

Answer:

200 + 50x

Step-by-step explanation:

depending on what x is, you multiply x by 50 and add 200, since 200 is the start up fee and the constant. the 50 dollars per month is a variable, since the more months you own the plan, the more money it would cost.

The amount paid for different weights of oranges at a farmer’s market are shown below.

Answers

The answer is 8lbs because 3/2 is 1.5 and 12/1.5 is 8

Answer:

8

Step-by-step explanation:

Well just looking at the problem you can take the first line of data (2 pounds of oranges for $3) and divide that to get how much one orange would be.

So:

$3.00 / 2 = $1.50

So now we have :

1 pound of oranges = $1.50

With this info we can take the $12 on the fourth line and divide it by the price of one pound of oranges ($1.50).

Like so:

$12.00 / $1.50

=

8

We can check this by inputting the 8 on the ?

If we do so we get 8 (8 pounds of oranges) x $1.50 (Price per 1 pound of oranges) = $12.00, which matches up with the $12 price the problem has given us.

Hope this helps!

Answer:

i believe it is 73 degrees

Step-by-step explanation:

Answer:

73°

Step-by-step explanation:

All interior angles of a triangle add up to 180°

We are given the angle measure of 17°. Since the triangle is a right triangle, it's safe to assume that the second angle is 90°.

90 + 17 = 107

180 - 107 = 73

The third angle should be 73°. Hope this helps!
