Let the angle be x.
Hence, its complement is 90 - x.
x = 3* (90 - x) - 70 = 270 - 3x - 70 = 200 - 3x
4x = 200
x = 50
Thus, the angle is 50°.

Answer is =4(3x+2)</span>
So it is really easy to solve firstly we can see how much does the first 10 boxes make which makes around 75$ obviously. Secondly 55$ for the next 10 boxes.
So for now we can simply calculate that we have spent around 130$ which means 20 boxes. The remaining money left is 18$ so we can buy 18/4.5 = 4 only 4 boxes with that money. Hence a total of 24 boxes.
10 runners ran fewer than 4 km
Call Anita's score

and Joelle's score

.
1) "<span>their combined total score for one game was 425 points"

2)"Anita’s score was 40 less than twice Joelle’s."
Therefore
