Answer: 21

Step-by-step explanation:

we have two simple equations:

1) 70=100%

2) x=30%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

70/x=100%/30%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 30% of 70

70/x=100/30

(70/x)*x=(100/30)*x - we multiply both sides of the equation by

70=3.33333333333*x - we divide both sides of the equation by (3.33333333333) to get x

70/3.33333333333=x

The fore, the answer is 21

Answer:

21

Step-by-step explanation:

30% of some quantity is equivalent to 0.30 times that quantity.

In this case, 30% of 70 is 0.30(70) = 21.

Find the equation of the line.
hoa [83]

Answer:

y=3x+3

Step-by-step explanation:

To find the slope, find two points and use the rise over run.

Some points you can use are (0, 3) and (1, 6)

The rise is 3 and the run is 1.

3/1 = 1.

The slope is 3.

To find the y-intercept, find the point where x = 0.

(0, 3)

The y-intercept is 3.

Now you can write an equation.

y=mx+b

m is the slope and b is the y-intercept.

y=3x+3
