Flip the bottom part after the "/" so you get ((x+3)/9)*(6/(x+12)) Cancel and multiply to get 2(x+3)/3(x+12) this is as simplified as it is going to get.

The Mendes family bought a new house 6 years ago for $104,000. The house is now worth $177,000. Assuming a steady rate of growth

dusya [7]

Well, the house grew 73 k throughout the 6 years, so it grew around 12.16 k each year. 12.16/104= approximately 11.6923%
Rounded to the nearest 1/10 of a percent, it's 11.7%

Eight randomly selected customers at a local grocery store spent the following amounts on groceries in a single visit: $216, $18

Answer:

a) 910

b) 828100

c) 144320

Step-by-step explanation:

a. ∑y

This is the sum of all values of y. So

$\sum y = 216 + 184 + 35 + 92 + 142 + 175 + 9 + 57 = 910$

b. (∑y)^2

This is the square of the sum, so the square of 910, that we found in the previous item.

910² = 828100

c. ∑y^2

This is the sum of the squares of each amount spent. So

$\sum y^2 = 216^2 + 184^2 + 35^2 + 92^2 + 142^2 + 175^2 + 9^2 + 57^2 = 144320$
