8hrs = 480mins
6hrs = 360 mins
472/480 = 0.983...
0.983... x 360 = 354
D) 354
All we need to do for this problem is multiply and divide. Let’s find the problems-per-minute!
6/13.5 = 0.44
Now we multiply this by 44 minutes to get the final answer.
0.44 * 44 ≈ 19 [you can’t solve 0.36 of a problem]
And there you have it! The inmates can solve 19 problems in 44 minutes online.
Answer:
It already is in the order.
-1.4, -1.38, -0.5, 0.76, 1.9
Answer:
Step-by-step explanation:
We have been given the equation:
And 
Second equation can be rewritten as:
We will solve the equations:
(1)
(2)
Multiply equation (1) by 5 and equation (2) by 3 we get:
(3)
(4)
Now, subtract (4) from (3) we get:
Now substitute in equation (1) we get:
Answer: x2 + 5x – 104 = 0
Step-by-step explanation:
- Distribute the x into the x + 5 to make it x2 + 5x
- Subtract 104 from the other side to set the equation equal to zero
- Final answer is x2 + 5x – 104 = 0
