Julio’s grandpa is 3 times as old as he is the sum of their age is 92 how old is grandpa

Julio is 23 years old.

Grandpa is 69 years old.

Step-by-step explanation:

To solve this equation you would make Julio and his grandpa a variable.

Now you would have one equation. (g = grandpa, J = Julio)

The equation for this would be g = J x 3

But the question states that the sum of their age is 92.

So we need another equation which is g + J = 92

so now we have g = J x 3

                           g + J = 92

We have to substitute g in the top equation to find out J.

Now the equation is J x 3  + J = 92

We simplify the problem and it is 4J=92

Then we divide 4 by 4 and 92 by 4 and that is 23

Now we find grandpa's age. We do this by putting Julio's age in the equation above g = J x 3

This would be g = 23 x 3

Now we multiply 23 and 3 and this is 69.

Our answers are J = 23 and G = 69

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
