2 hours traveling+1 hour waiting=3 hours, 6hours total-3= 3hours return trip.
X= mph on first leg
2hours*X=3hours*(X-20)
2x=3x-60
-1x=-60
x=60
60mph first leg, 40mph second leg
Val (huh, I didn't know that was an actual name) scored around 742 points, 30% fewer than Peeta. Since, 30% of 1060 can be found by multiplying 30% as a decimal (0.30), which means that 30% of 1060 is 318. However, it doesn't say that Val scored 30% of the points Peeta scored. No, it says that Val scored 30% LESS than the score Peeta scored. So, we're subtracting.
1060 - 318 = 742
So, Val scored 742 points.
First, expand the equation:
10x + 20 = 5x + 40
Now, isolate the variables:
10x - 5x = 40 - 20
Add or subtract:
5x = 20
Divide both sides by 5:
x = 4
There you have it!
Answer:
<h2>x = 7</h2>
Step-by-step explanation:
<u>Multiply the terms in the bracket</u>
We have
- 3x - 14 - 5x = - 70
- 8x - 14 = - 70
Using the addition property, add 14 to both sides
That's
- 8x + 14 - 14 = - 70 + 14
- 8x = - 56
<u>Divide both sides by - 8</u>
That's
<h3>
</h3>
We have the final answer as
<h3>x = 7</h3>
Hope this helps you
