Let's set up some simultaneous equations. Let the number of nickels be n, and the number of quarters be q. Now I'm from England so I had to look up the value of a nickel (I could guess the quarter though to be 25c), but apparently it's 5c
Okay we know that the total value of the coins is 150. This gives:
25q + 5n = 150
Rearranging to make n the subject:
n = 30 - 5q
Next, we use the second statement:
n = 2q - 5
Substituting this into the first equation:
2q - 5 = 30 - 5q
7q = 35
q = 5
Putting this value for q into the first equation:
n = 30 - 5(5) = 5
Hence he has 5 of each coin. I hope this helps :)
Answer:
x = 31.8°
Step-by-step explanation:
Applying the Law of Sines, we have:
Multiply both sides by 12
x = 31.8° (nearest tenth)
Answer:
GCF is 1
Step-by-step explanation:
The factors of 11 are: 1, 11
The factors of 18 are: 1, 2, 3, 6, 9, 18
Then the greatest common factor is 1
You find the slope by putting the points in the formula y2-y1/x2-x1
when you plug them in it should look like this
-4 -1/8-8
then you would add or subtract, when you do you would get
-5/0
this can't be divide so the slope of this 2 points is undefined
Hope this helped
