Question

I need help with this 3A. The vaccine made by Moderna must be stored at -56 degrees F. When administered the vaccine must be m degrees f warmer. Write an expression to find the temperature the vaccine must be when administered.3B. Evaluate it. The vaccine must be 133 degrees F warmer.

Answer 1

To answer this question, we need to translate the situation into an algebraical expression.

Part 3A

We have the following information:

1. The vaccine made by Moderna must be stored at -56°F.

2. When administered the vaccine must be m °F warmer.

Then, the expression to find the temperature the vaccine must be when administered is:

`T=-56^(\circ)F+m`

Part 3B

If we want to evaluate that, we need to substitute the value of m by 133°F as follows:

`T=-56^(\circ)F+133^(\circ)F`

Then, we have:

`T=77^(\circ)F`

We added integer numbers with different signs. In this case, we subtract the values and we write the sign of the number with the greatest absolute value (in this case, 133). Therefore, the final answer is a positive integer.

In summary, we have that:

1. The expression can be written as:

`T=-56^(\circ)F+m`

2. The evaluation of the expression for m = 133°F is:

`T=-56^(\circ)+133^(\circ)=77^(\circ)\Rightarrow T=77^(\circ)`
