Peter is saving money to buy new earbuds. The earbuds cost $200, but he has saved only 45% so far. How much more money does Peter need to save to buy the earbuds?

The Answer Is 90

Write 45% as 45100.

45100 of 200 = 45100 × 200.

Therefore, the answer is 90. If you are using a calculator, simply enter 45÷100×200 which will give you 90 as the answer.

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
