Lets get common fractions between 1/10 and 1/4, so we now have the fractions 2/20 and 5/20. After we add them we have 7/20. If 35% (7/20) of the points scored is 21, then total points scored is 60. (21 / .35)
The equation to represent the situation is 21 = 1/10x + 1/4x and the team scored a total of 60 points.
Given:
let
Total points scored by the team = x
Brian = 1/10 of x
= 1/10x
Joe = 1/4 of x
= 1/4x
Brian and Joe = 21 point
The equation:
Total points Brian and Joe scored = Brian + Joe
21 = 1/10x + 1/4x
21 = (2x + 5x) /20
21 = 7x/20
cross product
21 × 20 = 7x
420 = 7x
divide both sides by 7
x = 420 / 7
x = 60 points
Therefore, the equation to represent the situation is 21 = 1/10x + 1/4x and the team scored a total of 60 points.
