Working alone it takes Ryan 13.4 weeks to build a home.Jack can build the same home in 13.1 weeks how long would it take them if

dexar [7]

Answer: 6.62 weeks

Step-by-step explanation:

Time taken by Ryan to build a home = 13.4 weeks

Time taken by Jack to build the same home = 13.1 weeks

Let t be the time to complete a house if they work together, then

$\frac{1}{t}=\frac{1}{t}$ = $\frac{1}{\text{time taken by Ryan alone}}+\frac{1}{\text{time taken by Jack alone}}$

$=\frac{1}{13.4}+\frac{1}{13.1}\\\\=\frac{13.1+13.4}{175.54}\\\\=\frac{26.5}{175.54}$

$\\\Rightarrow\ t=\frac{175.54}{26.5}\\\Rightarrow\ t=6.62\ weeks$

Simplify the expression 10-4x(6+5-1) divided by 8+7

Eddi Din [679]

Simple,

writing out the problem...

$\frac{10-4x(6+5-1)}{15}$

Simplify it...

-4x(6+5-1)

-4x(11-1)

-4x(10)

-40x

Making it look like...

$\frac{10-40x}{15}$

Cancel out the common factors...

Thus making the answer:

$- \frac{2(4x-1)}{3}$ .
