Answer:
Rebecca has 18 nickels and 27 dimes
Step-by-step explanation:
Let x be the number of nickels Rebecca has, then 45-x is the number of dimes she has.
The total value of Rebecca's coins is $3.60.
1 nickel - 5 cents
x nickels - 5x cents
1 dime - 10 cents
45-x dimes - 10(45-x) cents
Total x nickels and 45-x dimes is 5x+10(45-x) cents that is $3.60=360 cents. So,
5x+10(45-x)=360
5x+450-10x=360
5x-10x=360-450
-5x=-90
5x=90
x=18
45-x=45-18=27
Answer:
6
Step-by-step explanation:
because u add them together and get 41, which is 5.125 and that means you need one more than 5 tables to sit everyone
Collinear points are points that are in the same line. Coplanar points are points that are in the same plane.
So first add them al together
10+14+40=64
16 ounces=1 pound
1pound/16ounce=1 because they are equal
so then multiply 64 ounce by 1 or 1pound/16ounce to cancel units and get
64 pound/16=4 pound
4 pounds total
Answer:
Points included: (1,0), (0,5)
Step-by-step explanation:
You already know one variable for the line, +5. Taking that +5 from the equation, you can understand that +5 will be counted as the y-axis, therefore, it'll be (0,5).
I've inserted an image of the line already graphed for you.
