Ostrovityanka [42]

Answer:

Yes

Step-by-step explanation:

Multiplicative Inverse of rational number:

When we multiply a rational number and its multiplicative inverse, we get 1

$\sf -5 \dfrac{2}{3}=\dfrac{-17}{3}$

Now,multiply this with (3/-17)

$\sf \dfrac{-17}{3}*\dfrac{3}{-17} = 1$

So, -5 2/3 is the multiplicatice inverse of 3/-17

200 + 10x = 120 + 15x now solve the equation to find x, the number of hours that both companies will charge the same ammount

torisob [31]

Answer:

Step-by-step explanation:

Given the equation, $200 + 10x = 120 + 15x$ , let's solve for x as follows,

Subtract 200 from both sides

$200 + 10x - 200 = 120 + 15x - 200$

$10x = - 80 + 15x$

Subtract 15x from both sides

$10x - 15x = - 80 + 15x - 15x$

$-5x = - 80$

Divide both sides by -5

$\frac{-5x}{-5} = \frac{-80}{5}$

$x = 16$
