Your answers are Equation A (8(4+x) = 72, and Answer C (5 hours).
1) Figure out how much of the total money she earned on Friday. 4*8= 32
2) She has 72 dollars total and 32 dollars were earned on Friday, meaning the rest was earned on Saturday. 72-32= 40
3) She earned 40 dollars on Saturday for 8 dollars an hour, so now you divide 40 by 8 and you get 5. She worked 5 hours on Saturday.
I’m sorry I’m confused it’s all spaced out can you put it in the comments and I’ll answer in there? Hope you have a nice day!
Answer:
The solutions to the equation are 1, 0.375.
Step-by-step explanation:
The equation is already in factored form.
The solutions to the system are the values of x that make one or the other of the factors be zero.
x -1 = 0 . . . when x = 1
8x -3 = 0 . . . when x = 3/8 = 0.375
There is only one variable, so no "ordered pairs" are involved.
The solutions are {1, 0.375}.
