Answer:
Step-by-step explanation:
Lines form 180 degrees on either side. The negative sign simply implies direction (clockwise instead of counter-clockwise), which is negligible as 180 is exactly half of 360 so you'd form the same line.
Answer:
x = 33
y = 41
Step-by-step explanation:
GIven
x: number of nickels
y: number of quarters
A nickel = $0.05
A quarter = $0.25
then we have the system of equations
0.05*x + 0.25*y = 11.90
x + y = 74
Which can be solved applying any of known methods. Then, the solution is
x = 33
y = 41
hope this was helpful.
It would round to 5 because 4.999 is closer to 5 than a decimal (idk if that's 100%)
Triangle area formula 1/2bxh
12/2=6 6x12=72
Y - 2 / 4
I don't really know how to explain it, but y - 2 / 4 is equivalent to 1/4y - 1/2
