A Table showing Freezing Temperatures in degrees with 2 columns and 6 rows. The First row, F, has the entries, negative 13, nega
Yuki888 [10]

Answer:

5F + -9  C= 160       39°F = 3.9

Step-by-step explanation:

A Table showing Freezing Temperatures in degrees with 2 columns and 6 rows. The First row, F, has the entries, negative 13, negative 4, 5, 14, 23. The second column, C, has the entries, negative 25, negative 20, negative 15, negative 10, negative 5.

The table shows temperatures below freezing measured in different units. Complete the equation in standard form to represent the relationship between F, a temperature measured in degrees Fahrenheit, and C, a temperature measured in degrees Celsius.

5F + -9 C = 160

39°F = 3.9°C rounded to the nearest tenth of a degree

help im stuck pls -- Refer to the table above. Determine the percent of all voters that did not vote Republican or Democrat but
dsp73

Answer:

9.9%

Step-by-step explanation:

Well, you would just divide the "other" category and the "total" category and then move the decimal over 2 spaces, because you need to multiply by 100 to turn your answer into a percent, so:

\frac{222}{2222} =0.09999...\\

Then once you multiply by 100, or move the decimal to the left 2 spaces, it becomes:

9.9%, which could be rounded to 10% or 9%.

Helen [10]

Answer:

4

Step-by-step explanation:

2 + 2 = 4

In order to really understand this we need to break it down into simple terms.

Basically what we are doing here is adding two things together.

Put it like this, you have two fish, and you get another two fish, you now have four fish.

If you don't understand anything or need me to explain it better please don't hesitate to ask.
