The formula to convert °c to °f is: °f = 32 + °c x 9 ÷ 5 the temperature of the water in a sports centre's swimming pool is 27° c. what is the temperature of the pool in °f?

80.6

Step-by-step explanation:

F = 9/5 C + 32

F = (9/5)*27 + 32               Substitute 27 into the equation

F = 243 / 5  + 32               Multiply 9 and 27 together  

F = 48.6 + 32                     Divide by 5

F = 80.6                             Add on 32

A very quick way to do this is to double your centigrade temperature and and 30 which you should be able to do in your head.

2*27 = 54 Add 30

54 + 30 = 84

This quick way will tell you if you get near the right answer.

Total degree around the circle is 360°.

So the equation would be,

x + 3x + 220° = 360°

Simple algebra,

4x + 220 = 360

4x = 360 - 220

4x = 140

x = 140 ÷ 4

x = 35
