Kamau is now 2 years older than Jane if James age is y now what will be the total age in 10 years​
cluponka [151]

Answer:

(2y + 22) years

Step-by-step explanation:

kamau is now 2 years older than Jane if Janes age is y now what will be the total age in 10 years​.

Answer: If Jane is y years old now and Kamau is 2 years older than Jane, therefore the age of Kamau now would be 2 + y years.

In ten years time Jane age would be y + 10 years while the age of Kamau would be y + 2 + 10 = y + 12 years.

To get their total age we just have to add their individual age. Therefore the total age in 10 years​  = Age of Kamau in ten years + age of Jane in ten years = (y + 12) + (y + 10) = y + 12 + y + 10 = y + y + 12 + 10 = 2y + 22 years

Order least to greatest: -5, -8, 2, 0, 3, 1, -1
UkoKoshka [18]

-Least to greatest-

<h2>-8   -5   -1   0   1   2   3</h2>

The numbers that have a negative sign in front of them come first because they are less than 0. The other numbers can be ordered by what comes first. For example, 3 is bigger than 1 so 3 would come after 1.
