Answer:
12
Step-by-step explanation:
3 x 4 = 12
The answer is c because all you are doing here is subbing the variable r for 5b.
Stem|leaf data: 11 12 13 21 22 23
1|1 2 3
2| 1 2 3
You're basically just splitting the numbers up. Tens in the stem row and ones in the leaf row. I hope this helps you!
Answer:
Slope in this case is -2
Y-Intercept in this case is 5, or (0, 5)
Step-by-step explanation:
In order to identify the slope and y-intercept, you must put the equation is y = mx + b form. This is quite simple! Don't panic! You got this :)
4x + 2y = 10
Move x to the right
2y = -4x + 10
Divide by y's coefficient
y = -2x + 5
Slope in this case is -2
Y-Intercept in this case is 5

- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set Up Equation</u>
3x + 3x + 10 + 2x + 10 = 180
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 8x + 20 = 180
- Isolate <em>x</em> term: 8x = 160
- Isolate <em>x</em>: x = 20
