the answer is "A" or "D" but I am prettu sure its "A"
Q + d = 63....q = 63 - d
0.25q + 0.10d = 10.80
0.25(63 - d) + 0.10d = 10.80
15.75 - 0.25d + 0.10d = 10.80
-0.25d + 0.10d = 10.80 - 15.75
-0.15d = -4.95
d = -4.95/-0.15
d = 33 <=== 33 dimes
q + d = 63
q + 33 = 63
q = 63 - 33
q = 30 <=== 30 quarters
All you have to do is try out both of the equations with each of the different choices.
200 = 45 (3) + 20
200 = 135 + 20
200 = 155
200 = 35 (3) + 60
200 = 105 + 60
200 = 165
So, this one does not work.
--------------------------------------------
180 = 45 (3) + 20
180 = 135 + 20
180 = 155
180 = 35 (3) + 60
180 = 105 + 60
180 = 165
So, this one does not work.
----------------------------------------------
200 = 45 (4) + 20
200 = 180 + 20
200 = 200
200 = 35 (4) + 60
200 = 140 + 60
200 = 200
So this one works.
The answer would be C.
I hope this helps and I'm sorry it took so long!
2x(2x + 3)
That would be -----------------------
2x^2 + 13x + 15
We should factor the denominator and then reduce the original fraction:
2x(2x + 3) 2x x
----------------------- = ------------- = ---------
(2x + 3)(2)(x+5) 2(x+5) x+5
This is true only for x not equal to -5, not equal to -3/2.
Answer:
1
Step-by-step explanation:
6/6 is equivalent to 1 as it is the same value. Think of it as Random Person at 6 of the 6 pieces of 1 cookie. So she ate all the pieces and had the whole cookie.
