How do you solve this?
|6x|+3=21

Step-by-step explanation:

1. 21= 6x+3

2. Subtract the 3 from one side which will cancel it out. Then go to the other side of the equation and subtract 3 from 21. The equation will now look like this- 19= 6x

3. Now divide by 6 on one side to cancel it out. Then go to the other side and divide 19 by 6.

X = 3.16666666667

Two things to remember when doing these equations

- Think of it as trying to get x by itself

- If you add, subtract, divide, or multiply on one side of the equation always remember to do the same thing to the other side.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
