Let us say that the number of weeks is "x" and the number of chores is "y".
If we state an algebraic expression for Janie's allowance it would be
3x+2y=13
However, there are two variables, hence many answers. To solve this problem, there must be more information about the relation between x and y.
Answer:
SY = 16
XY = 12
Step-by-step explanation:
15/20 = 12/SY
15SY = 240
SY = 16
15/20 = 9/XY
15XY = 180
XY = 12
It's 14.285714%
So, simplified it would be 14.3% because you round the 2 up since theres an 8 behind it.
The word "is" in this kind of problem typically means "=", so we know that something =-8. Since we're finding the number, we should start with the closest thing in the phrase given to that number. In this case, it's 3/4x. Finally, since we have the "14 less than", we need to add that in. Your answer is:
3/4x-14=-8. Now we can just solve!
+14 +14
3/4x=6.
*4/3 *4/3
x=8.
