Answer:
290.6 backpacks per year
Step-by-step explanation:
The average of 5 numbers is 1/5 of their sum:
average = (278 +310 +320 +242 +303)/5 = 290.6
The average number of backpacks given out in the last 5 years is 290.6, about 291.
We have the following equation,
and we need to find x. Then, by subtracting 16 to both sides, we have
and by dividing both sides by -2, we get
which gives
Therefore, the answer is x= -36
90+45=135
180-135=45
the measure of the third angle is 45
