Answer:
y=11
x=8
Step-by-step explanation:
This is Elimination
2x+2y=38
Subtract 2x on both sides 2y=-2x+38
Then Multiply 2(y=x+3) which equals 2y=2x+6
Solve by Elimination
2y=-2x+38
2y=2x+6
add the y's and since the x's are different those cancel out, then add 38 and 6.
then you do the equation 4y=44
divide both by 4
y=11
then you do 11=x+3
subtract 3 on both sides
x=8
and there you go
I hope this is how you wanted it solved
R = 8%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation:
r = (1/2)((2320/2000) - 1) = 0.08
r = 0.08
Converting r decimal to R a percentage
R = 0.08 * 100 = 8%/year
The interest rate required to get a total amount, principal plus interest, of $2,320.00 from simple interest on a principal of $2,000.00 over 2 years is 8% per year.
The formula for Area of a circle...
A=pi(radius)²
Answer:
O: The circle's name is "O"
Step-by-step explanation:
A circle is ALWAYS named for the center point. The point in the center of this circle is "O" so the circle is named "O"
