Answer:
<u>15/2</u>
Step-by-step explanation:
- 30/4=7.5
- convert the decimal to a fraction
- 7.5 would give you 15/2 in fraction form
- since you can't simplify 15/2 anymore, <u>15/2</u> would be your answer.
Hello from MrBillDoesMath!
Answer:
x^2 - 2 x - 15
Discussion:
(
x - (-3)) * ( x- 5) =
(x +3) (x-5) =
x^2 - 2 x - 15
It is a concave upward curve (looks like a "u") as the x^2 term causes the function to grow larger as x approaches +\- infinity.
Thank you,
MrB
A) .10 d + .25 q = 7.75
B) d + q = 40
Multiplying B) by -.10
B) -.10d -.10q = -4.0
Then adding this to A)
A) .10 d + .25 q = 7.75
.15q = 3.75
Quarters = 25
Therefore, dimes = 15
***************************************************
Double-Check
A) .10 d + .25 q = 7.75
A) .10 * 15 d + .25 * 25 = 7.75
A) 1.50 + 6.25 = 7.75
Correct!!
Answer:
146 is the answer because 180 - 34 = 146. And I did the test and it was right.
I hope this helped:)
It is a reciprocal. Multiplying is the opposite of Dividing, so if I multiply 3 times 4 I get 12. If i divide 12 by 3 I get 4.
