Answer:
-28
Step-by-step explanation:
If y = 98 when x is 14, y is always seven times x. We know this because x = y/7.
So if Y is seven times bigger, -4 * 7 = -28
4x^2 + 8x - 21 =
(2x - 3)(2x + 7) <==
The answer is $37.50. All you do is take $150 and divide it by 4.
Answer:
x = 5y/2, y = 2x/5
Step-by-step explanation:
2x = 5y
x = 5y/2, dividing 2 on both sides
y = 2x/5, dividing 5 on both sides
Assume that the number of points she scored in the first half is m.
We are given that she scored a total of 27 points and the the points she scored in the second half is n.
This means that:
Total score = score in first half + score in second half
27 = m + n
m = 27 - n
Therefore, your desired expression is:
m = 27-n
