I know y= 40 but what is x ?
puteri [66]

Answer:

x = 67; y = 40

Step-by-step explanation:

You are correct with y. Angles y + 23 and 63 are vertical, so they are congruent. That gives you y + 23 = 63, which gives y = 40.

To find x, look at angles 2x - 17 and 63.

They are adjacent angles whose outside rays lie on a line. Angles like these are called a linear pair, and they are supplementary. That means their measures add up to 180 deg.

2x - 17 + 63 = 180

2x + 46 = 180

2x = 134

x = 67

franklin market has 5:2 ratio of regular sodas to diet sodas. if there are 140 regular sodas how many diet sodas do they have?​
Amanda [17]

Answer:

56

Step-by-step explanation:

The ratio is 5 to 2, and we must keep it this way.

For example, if he had 10 regular sodas then the ratio would be 10:4.

If something happens to one side of this ratio, it needs to happen to the other so it remains balanced.

We need to find out how 5 got to 140. To find out, simply divide 140 by 5.

140 divided by 5 = 28

So, 5 was multiplied by 28 to get to 140.

Now, we need to multiply the 2 by 28 as well so it remains balanced.

2 x 28 = 56.

So, there are 56 diet sodas.
