Alex went to the store and purchased red and blue Jelly Beans. The ratio of red to blue Jelly beans is 3 to 7. If 140 Jelly Beans were in the bag, how many red Jelly Beans were in the bag? pl

42

Step-by-step explanation:

Total = 140 Jelly Beans

You are interested in the 3 part of the ratio.

Notice the word total. You should not be using 3/7 at all.

The ratio you want is 3/10. 10 represents the total.

3/10 = x / 140               Cross multiply

10 x = 3 * 140

10x = 420                     Divide by 10

10x/10 = 420 / 10

x = 42

Check

How many jelly beans are left?

140 - 42 = 98

Thats the number of Blue Jelly Beans.

Does 42/98 = 3/7?

Yes. Divide top and bottom by 14 and you get 3/7

p = 6s

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
