Eli had $10, but he lost some of it. his mom doubled the money he had left. eli wrote the expression 2(10 – k) to show how much money he has now, where k is the amount of money he lost. aisha wrote another correct expression, 20 – 2k, to also show how much money eli has now.

Both the equations would work

Step-by-step explanation:

If you want to see if both the equations would work, just try plugging in numbers. If you plug in 5, the first equation would give you 10 and the second equation would give you 10 too. This would be the same for every number. This shows that they were both right and both the equations are the same. All Aisha did was distribute the 2 onto both variables in the parenthesis.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
