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

the results from a pre-test for students for the year 2000 and the year 2010 are illustrated in the box plot. what do these results tell us about how students performed on the 29 question pre-test for the two years?

if we compare only the lowest and highest scores between the two years, we might conclude that the students in 2010 did better than the students in 2010. this conclusion seems to follow since the lowest score of 8 in 2010 is greater in value than the lowest score of 6 in 2000. also, the highest score of 28 in 2010 is greater in value than the highest score of 27 in 2000.

but the box portion of the illustration gives us more detailed information. the middle bar in each box shows us that the median score of 20 in 2000 is greater in value than the median score of 17 in 2010. further, we note that the box and whiskers divide the illustration into four pieces. each of these four pieces represents the same portion of students. so, the upper half of the students in 2000 scored in the same score range as the upper one-fourth of the students in 2010, see the illustration at a score of 20.

by considering the upper one-fourth, upper half, and upper three-fourths instead of just the lowest and highest scores, we would conclude that the students as a whole did much better in 2000 than in 2010. we would conclude that as a whole the students in 2010 are less prepared than the students in 2000.

in this section, we discuss box-and-whisker plots and the five key values used in constructing a box-and-whisker plot. the key values are called a five-number summary, which consists of the minimum, first quartile, median, third quartile, and maximum.
