Acopy machine makes 60 copies per minute a second copy machine makes 80 copies per minute. the second machine starts making copies 2 minutes after
the first machine starts both machines stop making copies 8 minutes after the first machine started. together, the 2 machines made how many copies?

c

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

abde or 1,2,4, 5 is the answer

step-by-step explanation:

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values
