PLEASE HELP! The formula F = 95C + 32, where C stands for temperature in degrees Celsius, is used to convert Celsius to Fahrenhe

Masteriza [31]

The temperature is 86°F when the temperature is 30°C.

Step-by-step explanation:

Formula for Celsius to Fahrenheit;

F = $F=\frac{9}{5}C+32$

Where C stands for temperature in degrees Celsius.

Given,

Temperature in Celsius = 30 degrees

Temperature in Fahrenheit = $\frac{9}{5}*30+32$

Temperature in Fahrenheit = $9*6+32$

Temperature in Fahrenheit = $54+32 = 86\ degrees\ Fahrenheit$

The temperature is 86°F when the temperature is 30°C.

Answer:

mary=10 jack=15

Step-by-step explanation:

After 4 years Mary (x+4), Jack's age (x+5) + 4.

sum of the ages after 4 years :(x+4) + (x+5) +4=33

Simplifying the equation:

2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age

10 + 5 = 15 which is Jack's age.
