how is solving inequalities with addition and subtraction similar to and different from solving equations with addition and subtraction?

Answers

That technique for solving equations is: Whatever you do to one side of the equation, you have to do to the other side to preserve the equality The technique for solving inequalities is: Whatever you do to one side of the inequality, you have to do to the other side to preserve the inequality. the techniques are the same. The difference between solving equations and solving inequalities is: If you multiply or divide an inequality by a negative number, then the inequality reverses. !!!!!

Answer:

The third graph is correct

Step-by-step explanation:

Hiiii,

Since the sign is < and doesn't have a line underneath (or equal to), it means we have an open circle. We also know that the line has to go to the left because all the values that go to the left make the inequality true. If they go to the right, it won't be true because the value will be greater than 21 and we need it to be less than 21.

Hope this helps :)

62,57,61

Step-by-step explanation:

(12x +2)  + (12x-3 ) + (13x-4)  = 180

37x  = 180 -2 +3+4

37x = 185

x = 185/37 =  5

One angle =(12x +2) = 62

Second angle =(12x-3 ) = 57

Third angle = (13x-4) = 61

I hope im right!!

A claw arcade machine contains stuffed animals and mystery boxes. There are 72 items in the machine. Winning a stuffed animal has twice as many favorable outcomes as winning a mystery box. How many of each item is in the machine?

Answers

Answer:

50 stuffed animals and 22 mystery boxes.

Step-by-step explanation:

Firstly, we assign variables.

Let the number of stuffed animals be x and the number of mystery boxes is y

The probability of selecting a stuffed animal is x/72 while the probability is selecting a mystery box is y/72

Now, since the total probability can be 1:

This means that

x/72 + y/72 = 1 •••••••(i)
