I do not think there are more.
I assume that the "d2" was a typo as a problem such as this with 2 variables would require a <em>system of equations</em>.
I also assume that the ? is a typo and will replace it with 0, however you can repeat my steps with whatever it actually it.
I assume that the correct form is 2 + 3a + 6 + a = 0
2 + 3a + 6 + a = 0
Combine like terms
8 + 3a + a = 0
8 + 4a = 0
move 8 to other side
4a = -8
a= -8/4
a = -2*
plug this value of a into the original equation
2 + 3(-2) + 6 + (-2) = 0
The statement is true!
<em>* This probably isn't your answer! Repeat my steps with whatever the value of "?" is.</em>
Answer:
There is a formula for this:
[Worker 1 Time * Worker 2 Time] / [Worker 1 Time + Worker 2 Time]
[2 * 1.5] / [2 + 1.5] = 3.0 / 3.5
= 0.8571428571 Hours =
51.43 minutes
Both Jenna and Juan are INCORRECT.
Step-by-step explanation:
the formula we use is
distance = speed * time
In the question we are provided with the info that
speed = 56 mph and
time = 3 hours 45 minutes = 3 + 45/60 hours = 3+ 0.75 hours = 3.75 hours
Now lets plug the values in the formula
distance = speed * time = 56 mph * 3.75 hours
distance = 210 miles
