Mathematics: Smith Engineering is in the process of reviewing the salaries of their surveyors. During this review, the company found that an experienced surveyor can survey a roadbed in 7 hours. An apprentice surveyor needs 9 hours to survey the same stretch of road. If the two work together, find how long it takes them to complete the job.

Hello!We can find the value of t using the slope formula:Plug in the given slope and coordinates into the appropriate places:Simplify:Multiply both sides by 2 to begin isolating for t. Simplify and solve for t:...

T = 3.5 hours

Step-by-step explanation:

this is a rate problem.

an experienced surveyor takes 7 hours to survey a roadbed

an apprentice surveyor takes 9 hours to survey a roadbed

the rate of the experienced surveyor = $\frac{1}{7}$

the rate of the apprentice surveyor = $\frac{1}{9}$

if the two work together , $\frac{1}{T} =\frac{1}{7} +\frac{1}{9}$

T = $\frac{56}{16}$

T = 3.5 hours

Hello!

$\large\boxed{t = -8}$

We can find the value of t using the slope formula:

$slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Plug in the given slope and coordinates into the appropriate places:

$5 = \frac{2-t}{3-1}$

Simplify:

$5 = \frac{2-t}{2}$

Multiply both sides by 2 to begin isolating for t. Simplify and solve for t:

$5 * 2 = 2 - t\\\\10 = 2 - t\\\\8 = -t\\\\t = 8$
