Answer:

The given system of equations has infinitely many solutions.

Step-by-step explanation:

Given equations are:

4x-2y = 28

2x-y = 14

From equation 2:

$2x-14 = y$

Putting in equation 1:

$4x-2(2x-14) = 28\\4x-4x+28 = 28\\28 = 28$

When this happens in the solution of a system i.e. same constant on both sides of equation, the system of equations has infinitely many solutions.

Hence,

The given system of equations has infinitely many solutions.

Write 125 as a repeated multiplication 5s. Then write it as a power.

Maru [420]

Answer:

125 = 5 * 5 * 5 = 5^3

Step-by-step explanation:

125 is equal to 5 times 5 times 5, and a power is a way to write repeated multiplication, just by saying what number it is and the putting a ^ sign and then saying how many times there is that number. There is 5 three times, so the power is 5^3.

Tyrone saved 24$ of the 60 that he earned mowing lawns .what percent of his earnings did tyrone save

mezya [45]

If 24 of the 60 were saved then the percent saved is

(24/60) x 100

Let's imagine for a second that all 60 was saved, then 100% of the money would be saved. Which makes sense, because

(60/60) x 100 = 100%

So the amount saved dived by the amount earned all times 100 is the percent saved.
