Alejandra was working on an animal report for school. she worked on it for 4 hours in a week. how many hours did she work on the project each day?

0.57 hours each day or 34.28 minutes each day.

Step-by-step explanation:

1. You know that:

-Alejandra worked on the animal report for school for 4 hours in a week.

- A week has seven days.

2. Therefore, to calculate the number of hours she worked on the project each day (which you can call ), you can divide the number of hours  worked on in a week by 7 days.

3. Therefore, you obtain the following result:

Multiply the result by 60 to obtain the time in minutes, then:

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
