Answer 1

Answer: remember you can do ANYTHING to an eqyation as long as you do it to BOTH SIDES (except divide by zero)

tr to isolate the unknown by itself

3x+3=12
minus 3 both sides
3x+3-3=12-3
3x+0=9
3x=9
divide by 3
x=3

x/4+4=8
minus 4
x/4=4
multiply 4
x=16

Answer 2

Answer: 3x + 3 = 12

To solve these type of equations, we need to apply the inverse operation to both sides of the equation. Next, we'd isolate the variable.

Here's how it's done:

3x + 3 = 12
- 3 -3

Notice, we subtracted 3 from both sides.

3x = 9
3x/3 = 9/3
x = 3

Now for the other:
x/4+4=8
- 4 -4

8 - 4 = 4

x/4 = 4
x/4 * 4/1 = 4 * 4
x = 16

We're officially done:

1st one: x = 3
2nd one: x = 16

Francois baked just enough cookies to fill all the orders at his bakery. While the cookies were cooling, a kitchen assistant knocked over a cooling rack and spilled 1 2 % , percent of the cookies onto the floor. Francois had to bake 36 more cookies to replace them.

Answers

If 36 = 12% of the cookies, the total number of cookies equals x in the following equation:
$(36)/(.12)= (x)/(1)$

So $x = (36)/(.12) = 300$ cookies in total!

Mike sees 3 more fish than Chris. Chris sees 6 fish. How many fish does Mike see? It says use comparison bars. Thanks

Answers

Chris sees 6 fish.

Mike sees 3 more fish than Chris.

6 + 3 = 9

So on your bar, you have Chris's number of fish he saw, 6, and you have 3 being added to that on Mike's bar.

Mike sees 9 fish. 6 + 3 = 9.
