Step-by-step explanation:
<u>Step 1: Define Equation</u>
72 = 5x + 22
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 22 on both sides: 50 = 5x
- Divide 5 on both sides: 10 = x
- Rewrite: x = 10
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 72 = 5(10) + 22
- Multiply: 72 = 50 + 22
- Add: 72 = 72
Here we see that 72 does indeed equal 72.
∴ x = 10 is the solution to the equation.

Answer:
warmer by 30.2 degrees
Step-by-step explanation:
It might help to think of these values plotted on a number line. Both temperatures will be left of zero, with -63°C being farther to the left (colder).
The difference can be found by subtracting the colder temperature from the warmer one:
-32.8 -(-63) = -32.8 +63 = 63 -32.8 = 30.2 . . . degrees
The South America temperature -32.8°C is 30.2° warmer than the North America temperature.
Answer:
The slope of a line would be your m in the equation. So, when you have your y=mx+b you would have the slop
