The relationship between the temperature in celsius to the temperature in Fahrenheit is C = (5/9)(F - 32)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let F represent temperature measured in degrees Fahrenheit, and C, a temperature measured in degrees Celsius.

At 0°C, the temperature is 32°F. Also at 100°C, the temperature is 212°F, hence:

$C-0=\frac{100-0}{212-32} (F-32)\\\\C=\frac{5}{9} (F-32)$

The relationship between the temperature in celsius to the temperature in Fahrenheit is C = (5/9)(F - 32)

The physical education instructor asked each student to do a total of 36 pull-ups and push-ups in 1 minute. The instructor wante

NeTakaya

Answer: Pull-ups = 4 and push up = 32

Step-by-step explanation:

Let x represents number of pull ups in one minute.

And, y represents number of push ups in one minute.

Therefore, According to the question,

Each student to do a total of 36 pull-ups and push-ups in 1 minute.

⇒ x+y= 36

But, again from equation, The instructor wanted students to do 8 times as many push-ups as pull-ups.

Therefore, 8x = y

Thus, required system of linear equations that represents this situation is,

x+y= 36 and 8x = y , where x is the number of pull ups and y is the number of push ups in one minute.

By solving these two equations we get, x=4 and y= 32

That is, In one minute 4 pull ups and 32 push ups are required.
