What we wanna do is flip this equation. Assuming we are solving for x

\frac{3}{5}x  +  \frac{-9}{5} = y + 1 < Flipped

Add 9/5 to both sides!

\frac{3}{5}x +  \frac{-9}{5} +  \frac{9}{5}  = y + 1 +  \frac{9}{5}  &#10;&#10; \frac{3}{5}x = y +  \frac{14}{5}

Then we wanna divide both sides by 3/5

\frac{3}{5}x/ \frac{3}{5} = y +  \frac{14}{5}/ \frac{3}{5}&#10;&#10;x =   \frac{5y + 14}{3}

To the nearest degree, what is the measure of each exterior angle of a regular decagon?
aniked [119]

Answer:

Exterior angle of a decagon will be 36°

Step-by-step explanation:

Measure of all interior angles of a polygon is represented by (n - 2)×180°

where n is the number of sides of the polygon.

Now we have to calculate the exterior angle of a regular decagon.

As we know exterior angle of polygon is supplementary of the interior angle.

So we will calculate interior angle first.

Sum of interior angles of decagon = (n - 2)×180° = 8×180° = 1440°

Since decagon is regular so all angles will be same.

So one angle of decagon = 1440 ÷ 10 = 144°

Now exterior angle = 180 - 144 = 36°

Each exterior angle of a decagon will be 36°.

If you assume the samples are representative how many whole wheat bagels might you infer are sold at each store
Alexxandr [17]

Maurine owns three bagel shops. Each shop sells 500 bagels per day. Maureen asks her store managers to use a random sample to see how many whole wheat bagels are sold at each store each day. Shop A has total of 50 bagels in sample and 10 are whole wheat bagels. Store B has a total of 100 bagels in sample and 23 are whole wheat bagels. Shop C has 25 total bagels in sample and 7 are whole wheat bagels.

We find fraction of whole wheat bagels to the sample for each shop using given information

Shop A = \frac{10}{50}  = 0.20

Shop B = \frac{23}{100}  = 0.23

Shop C = \frac{7}{25}  = 0.28

The number of whole wheat bagels for each shop that sells 500 bagels per day

Shop A = 0.20 * 500= 100

Shop B = 0.23 * 500= 115

Shop C = 0.28 * 500= 140
