1/5x+ 1/3y would be the correct response.
16:29:15 I think that would be it but, I'm really sorry if that's not right
Substitute
4x+2=x-4
Then solve
3x=-6
x=-2
Substitute answer into an equation to find y
y=-2-4
y=-6
So you solution is:
(-2,-6)
2(3x-4) = 5x+6
First, expand the bracket.
6x-8=5x+6
Next, move the variables to the same side.
x-8=6
Move the -8 to the other side, change to +
x=6+8
x=14
Charlie’s solution is incorrect. When expanding the bracket, he changed the - to a +.
Answer: $2,561.50
(I = A - P = $211.50)
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 18%/100 = 0.18 per year.
Solving our equation:
A = 2350(1 + (0.18 × 0.5)) = 2561.5
A = $2,561.50
The total amount accrued, principal plus interest, from simple interest on a principal of $2,350.00 at a rate of 18% per year for 0.5 years is $2,561.50.
