The formula to convert celsius to fahrenheit is F=9/5c+32. convert 87° F to celsius .Round to the nearest degree

Answers

Answer:

31°C

Step-by-step explanation:

The formula to convert Celsius to Fahrenheit is F=9/5c+32.

To convert 87° F to Celsius plug in F = 87 in the above formula, we get

87 = $-(9)/(5) c + 32$

Now we have to isolate the variable and the constant.

Subtract 32 from both sides, we get

87 - 32 = $-(9)/(5) c + 32 - 32$

55 = $-(9)/(5) c$

Multiply both sides by the reciprocal of -9/5

Which is called inverse operations to find the value of C.

The reciprocal of -9/5 is -5/9

$-(5)/(9) *55 = -(9)/(5) *-(5)/(9) C$

C = 275/9

C = 30.5°

To round off to the nearest degree, we get

31°C

The answer would be 30 or 31 degrees.

Solve the equation for y:
2x + 5y = 20

Answers

Answer:

y = $(20-2x)/(5)$

Step-by-step explanation:

Given

2x + 5y = 20 ( isolate the term in y by subtracting 2x from both sides )

5y = 20 - 2x ( divide both sides by 5 )

y = $(20-2x)/(5)$

The Answer will be y=4

22.6 is an outlier for the second data set. The reason for this is that 22.6 is nowhere near the rest of the data points. Outliers are numbers that are either a lot bigger or a lot smaller than the rest of the other numbers in the set. In this case, 22.6 is a lot bigger.
