Answer:

27.2 cm

Step-by-step explanation:

14 cm / 2.5 = 5.6 cm, and

20 cm / 2.5 = 8 cm.

Then the new perimeter would be P = 2L + 2W, or, in this case:

P = 2(8 cm) + 2(5.6 cm) = 27.2 cm

-3x/5 divided by 4/5<br><br> Please explain how to solve this.
zloy xaker [14]
You need to keep -3x/5, change the division sign to multiplication and flip 4/5 so it becomes 5/4. When you did that, -3x/5 times 5/4 is equal to -15x/20. Lastly, you simplify it so the answer is -3x/4

Time taken to travel 20 m = 1 min
Time taken to travel 360m = x min
therefore:
1/20=x/360

(cross multiply)
20 x =360(isolate x by dividing both sides by 20)
x = 360
20 x
= 18 mins.

Answer:

The answer is 7/6x - 75.

Step-by-step explanation:

17 - 1/5x +2/3x - 92 + 7/10x
