The first thing we must do for this case is to define variables.
We have then:
x = number of dimes
y = number of half-dollars
We write the system of equations:
x + y = 36
0.10x + 0.50y = 12
Solving the system we have:
x = 15
y = 21
Answer:
He has 15 dimes
Answer:
x=80
Step-by-step explanation:
The angle of a line is 180*.
The equation would be (x+20)+x=180
Subtract 20 from both sides: 2x=160
Divide by 2: x=80
That's your answer!
I hope this helps!

Answer:
b = (-5, 2)
Step-by-step explanation:
b = 2m - a = 2(1, -1) -(7, -4) = (2-7, -2+4)
b = (-5, 2)
