Match each inequality to the number line that represents its solution

We have to establish a feature that gives us the first answer. When going with a number line and plotting with a ≤ or ≥ symbol, the point will be closed or black and when going with a < or > symbol, the point will be opened or white. So we can safely say that 75 < 69-x is the 3rd one. So now when solving an inequality, you just have to move the number on the side of X to the other one and to do that, we have to do the opposite value that it has. (ex. 130+x > 50= x > -80, we subtracted) So we apply that to every inequality and find where we need to put them in. That gives us the answers of 150 + x ≤ 144 is the 4th one, x-51 ≤ -43 is the 1st one, and x-99 ≤ -104 is the 2nd one.

the first one that is x-99....... goes to the second answer box

the second that is x-51......... goes to the first answer box

the third that is 150+x......... goes to the fourth answer box

the fourth that is 69-x......... goes to the third answer box

There are 30 coins all dimes and quarters on the table worth
nignag [31]

Answer:

We can set up a system of equations.

x + y = 111

0.25x + 0.10y = 18.30

x + y = 111

Subtract 'y' to both sides:

x = -y + 111

Plug in '-y + 111' for 'x' in the 2nd equation:

0.25(-y + 111) + 0.10y = 18.30

Distribute 0.25 into the parenthesis:

-0.25y + 27.75 + 0.10y = 18.30

Combine like terms:

-0.15y + 27.75 = 18.30

Subtract 27.75 to both sides:

-0.15y = -9.45

Divide -0.15 to both sides:

y = 63

Plug this back into any of the two equations to find the 'x' value.

x + y = 111

x + 63 = 111

Subtract 63 to both sides:

x = 48

So there are 48 quarters and 63 dimes.

Step-by-step explanation:

Hope This Helps!
