<em />\rule{50}{1}\large\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}

First of all, We need to multiply by the denominator (10) on both sides:-

\longmapsto\sf{\displaystyle\frac{-x+8}{10} \times10=-7\times10}

On the left-hand side, the 10s cancel as follows:-

\longmapsto\sf{-x+8=-7\times10}

On the right-hand side, we multiply -7 times 10:-

\longmapsto\sf{-x+8=-70}

Subtract 8 on both sides:-

\longmapsto\sf{-x=-70-8}

We get

  \longmapsto\sf{-x=-78}

And finally, Divide by -1 on both sides:-

\longmapsto\sf{x=78}

<h3>Good luck with your studies.</h3>

madam [21]

Answer:

<h2>               - 320</h2>

Step-by-step explanation:

a₁ = 10

a₂ = 6

d = a₂  - a₁ = 6 - 10 = -4

n = 16

a₁₆ = a₁ + (n-1)•d = 10 + (16-1)•(-4) = 10 - 60 = -50

S_{n}=\dfrac{a_1+a_n}{2}\cdot n\\\\\\S_{16}=\dfrac{10-50}{2}\cdot 16=-40\cdot8=-320

Mr Adams worked 78 hours during his six-day work week if he worked the same number of hours every day, how many hours did he wor
Vedmedyk [2.9K]

Answer:

Mr Adams worked for 52 hours in four days.

Step-by-step explanation:

To get 52, you divide 78 and 6 and get 13. 13 is how many hours he worked a day. Since we need to find out how many hours he worked for 4 days, we add 13 4 times. If we add, the equation would look like this: 13+13+13+13=52. We can multiply also since it's easier. If we multiply our equation would be 13×4. Therefore, Mr Adams worked 52 hours in four days. Hope this helped
