R + b = 21
2b = r

now we sub eq 2 into eq 1
r + b = 21
2b + b = 21
3b = 21
b = 21/3
b = 7

2b = r
2(7) = r
14 = r

so there are 7 bluejays (b) and 14 robins (r)...for a total of 21

Find the distance between the points (-7,-6) and (5,-6) .
PilotLPTM [1.2K]

<u>Answer:</u>

12 units

<u>Step-by-step explanation:</u>

We are given these two points, (-7,-6) and (5,-6), and we are to find the distance between them.

We know the formula for finding the distance between two points:

<em>Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}</em>

So putting in the values of the given coordinates in the above formula to get:

Distance = \sqrt{(5-(-7))^2+(-6-(-6))^2} = \sqrt{144 + 0}  =12

Therefore, the distance between the two given points is 12 units.
