This is my grade. A school bought 1,000 erasers as part of an order for supplies. The total cost of the erasers was $30. What was the cost of 1 eraser? Write an equation to show how you solved the problem.

Step-by-step explanation:

30 divided by 1000 which is the 1000 erasers equals... 0.03 dollars per eraser

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
