Answer:

Step-by-step explanation:

We know: measures of angles in a triangle add up to 180°.

Therefore we have the equation:

$\gamma+\gamma+72^o=180^o$ <em>subtract 72° from both sides</em>

$2\gamma=108^o$ <em>divide both sides by 2</em>

$\gamma=54^o$

a painter can finish a house in 5 hours. Her assistant takes 7 hours to finish the same job. How long would it take for them to

mars1129 [50]

Answer:

Step-by-step explanation:

Call the first person A who can do the job in 5 hours.

Call the second person B who can do the job in 7 hours.

The formula for this problem is

Time = A*B/(A + B)

Time = 5*7 / (5 + 7)

Time = 35 / 12

Time = 2 hours and 11/12 of an hour.

The answer is D.

-4x+2=-6;2 us this a solution to the equation

Alex17521 [72]

Hi there! Yes, x = 2 is a solution to this equation.

Let's solve this equation step by step!
$- 4x + 2 = - 6$

Subtract 2 from both sides.
$- 4x + 2 - 2 = - 6 - 2 \\ - 4x = - 8$

Now divide both sides of the equation by -4 (and remember that when dividing two negatives we end up with a positive).
$x = \frac{ - 8}{ - 4} = 2$

And therefore x = 2 is a solution to this equation.
~ Hope this helps you!
