About 1.5 hours since you would do distance divided by the rate to get the time.
Let X be width <span>of a rectangle, then
(x+8) - </span><span>length
(x+x+8)*2 = 52
x+x+8 = 52/2
2x+8 = 26
2x = 26-8
2x = 18
x = 18/2
x = 9 cm
Answer: 9 cm.</span>
Answer:
<h3>-12 + 25 </h3>
As it is given in the question that 12° F is below zero is it is taken as minus and 25 °F is risen so it is taken as positive
<span>Let the first number be x.
Then the second number is 3x.
Then the third number is (x+100).
Sum of the numbers=500
x+3x+(x+100)=500</span>
<span>4x+(x+100)-500=0
</span><span>5x=400</span>
<span>x=80
</span><span>The first number is 80.
The second number is 240.
The third number is 180.
We can check by adding all three of those numbers together: 80+240+180 = 500
