So we can set up a simple equation for this, where the word “what” is a variable, x. This equation is 3 - x=11. Then we subtract 3 from both sides, giving us -x=8. We can divide both sides by -1, giving us x=-8. The answer would be -8. Hope this helped.
Ok, so we know that the radius of Sphere A is 24 cm, and we know that the diameter of Sphere B is 42 cm. To find the radius of Sphere B, all we need to do is divide the diameter by two. The radius of Sphere B is 21 cm. 24 times what factor is 21? Well,

is equal to 21. All we need to do now is simplify it. Divide the numerator and denominator by 3, and we get
0.00067
You always want the period to the right of the first number meaning you’ll start from there counting backwards because it is negative.
