The high school English teacher assigned a research paper that was to be 15 pages long. If she has 25 students in her class, and she plans to read 25 pages each night, how many weeks and days will it take to grade all the papers?

ok so first we have to multiply 15*25

375

now we divide by 25

375 divided by 25=15

Hope This Helps!!!

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

answer: 12

step-by-step explanation:

because yes
