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
No because he only surveyed the members of the chess club
For this case we have the following inequality:
We must clear "y", so, we have the following steps:
1st step:
Apply distributive property to the right side of the inequality:
2nd step:
We add similar terms:
3rd step:
We add 48 to both sides of the equation:
4th step:
We divide between 22 on both sides:
Thus, the result is given by: 
Answer:
Option 1
Answer:
Step-by-step explanation:
x^2 + 8x +15 is the area
x+5 is the length
x+3 is the width
(x+5)(x+3)=
x^2 + 3x +5x +15
x^2 +8x + 15
