Answer:
Step-by-step explanation:
x= money earned per hour working as a cashier.
y=money earned per hour working delivering newspapers.
We propose the following system of equations:
5x + 4y =77
6x + 3y=78
We solve the system by reduction method:
-6*(5x+4y=77) ⇒ -30x-24y=-462
5*(6x+3y=78)⇒ 30x+15y=390
---------------------------
-9y=-72 ⇒ y=-72 /-9=8
Now, we get the value of "x" replacing the value of "y" by "8" in any part of the equation above.
5x + 4(8)=77
5x+32=77
5x=77-32
5x=45
x=45/5=9
therefore;
money earned per hour working as a cashier= $9/ hour
money earned per hour working delivering newspapers=$8/hour
Answer: x^2 + 3x - 1.
Step-by-step explanation: We need to divide x^3 + 5x^2 +5x-2 by x+2. This is dividing polynomials. Divide each number by x and multiply the quotient by 2 and subtract the answer.
Rectangle:
2x+2x+2x+7+2x+7
8x+14
Hexagon:
2x+2x+x+x+x+8+x+6
8x+14
They’re equal
Answer:
$2.70
Step-by-step explanation:
0.7 kg / $ 1.89= 1.0 kg / x
Cross multiply: 0.7x = 1.89
Divide 1.89 by 0.7:
The result is $ 2.70 for 1 kilogram of jelly beans.
