Answer:
-600
Step-by-step explanation:
Jackson's initial score was 300, then his later score became -300, so you know that he had to lose points.
-300=300+x
** x represents the point change
Then just solve the equation by getting x by itself. You do this by subtracting 300 from both sides:
-300=300+x
-300 -300 = -300-300+x
-600 = x
Answer:
10 miles
Step-by-step explanation:
Let m represent the number of miles Kayla runs. We want to find m such that ...
0.50m = 5.00
Divide by the coefficient of m:
m = 5.00/0.50 = 10
Kayla has to run 10 miles to get the same donation from both parents.
(((x + y) / 3) + (1 / x)) / (5 + (15 / x))
The best way is to make it one fraction.
Multiply by ((3x/3x) / (3x/3x)) to remove the other fractions.
((x(x + y)) + 3(1)) / (5(3x) + 3(15))
(x^2 + xy + 3) / (15x + 45)
Then factor to simplify
(x^2 + xy + 3) / (3(x + 15))
