8 2/3+6 2/5

i need help

15 1/15

Step-by-step explanation:Rewriting our equation with parts separated

=8+23+6+25

Solving the whole number parts

8+6=14

Solving the fraction parts

23+25=?

Find the LCD of 2/3 and 2/5 and rewrite to solve with the equivalent fractions.

LCD = 15

1015+615=1615

Simplifying the fraction part, 16/15,

1615=1115

Combining the whole and fraction parts

14+1+115=15115

Solution by FormulasFirst:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

263+325

Applying the fractions formula for addition,

=(26×5)+(32×3)3×5

=130+9615

=22615

Simplifying 226/15, the answer is

=15 1/15

A)  both functions are linear

B) f(x) = 7446.4x + 178713.6 and f(x) = 11000x + 179000

C) House 2 will value $106894.4 more than house 1.

Step-by-step explanation:

A) Value Increase from year 1 to year 2:

House 1: 193,606.40 - 186,160 = 7446.4

House 2: 201,000 - 190,000 = 11000

Value Increase from year 2 to year 3:

House 1: 201,350.66 - 193,606.40 = 7744.26

House 2: 212,000 - 201,000 = 11000  

This means that a constant increament in x variable gives a constant increament in both houses vales. Then, both functions are linear.

B) The slope is the same as the value increment from one year to the next one.

slope (m) of House 1: 7446.4

slope (m) of House 2: 11000

General formula of a line:

f(x) = mx+b

Replacing with a known point:

House 1

186,160 = 7446.4(1) + b

b = 186,160 - 7446.4 = 178713.6

equation: f(x) = 7446.4x + 178713.6

House 2

190,000 = 11000(1) + b

b = 190,000 - 11000 = 179000

equation: f(x) = 11000x + 179000

C) Replacing x = 30 into each equaiton:

Value of House 1 after 30 years

f(x) = 7446.4(30) + 178713.6 = 402105.6

Value of House 2 after 30 years

f(30) = 11000(30) + 179000 = 509000

Then, house 2 will value 509000 - 402105.6 = $106894.4  more than house 1.
