Andy is one-fourth as old as his grandfather, who is 76 years old. write an equation to determine whether andy is 19 or 22 years old.

We know that if we multiply Andy's age by four we obtain 76. Lets assume that Andy's age its x. so
4*x=76
Now we have to solve equation
4*x=76     /:4 divide both sides by 4
x=19 - its the answer

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3

step-by-step explanation:

yes it is1. move over 2 points on the x-axis2. move over 2 points on the y-axis
