A school purchased T-shirts to sell for a fundraiser. The school spent $684 for the T-shirts. Each T-shirt will sell for $12.

If the question is How many T-Shirts does the school have, it will be 57 T-Shirts

Step-by-step explanation:

684 divided by 12 is 57

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

50-60=10
