First translate words to symbols
The word is translates to =
The word multiplied translates to *
The letter n is a variable, do nothing with it
90=123n
P.S. If its multiplication and there is something to multiply with a variable
Dont do 123 * n or n * 123
Write it 123n (its the proper way)
Is (x^3 -1)/x odd or even?
I believe the answer is even if you divide them out.
The answer is 7/8. when converted into decimal , it becomes 0.8 something which is greater than all and so farthest from 0
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
