Answer:
5x-2x-x = 10 9z • 7p = 378
Step-by-step explanation:
With equations like these you're basically just plugging numbers in where there are variables. so if you have 5x-2x-x when x=5, you just plug in 5 wherever x is. 5x-2x-x turns into (5•5)-(2•5)-(1•5). you multiply the expressions in the parentheses to get 25-10-5 and then you simply subtract.
1. 5x-2x-x
2. (5•5)-(2•5)-(1•5)
3. 25-10-5
4. 10
We can do the same thing with your second example. 9z•7p when z=2 and p=3. When there is a z, you plug in a 2. When there is a p, you plug in a 3.
1. 9z•7p
2. (9•2) • (7•3)
3. 18 • 21
4. 378

Step-by-step explanation:
in y > 2x equation, the line will be dashed and u will shade above the line
Set the angles equal to 180
x + 2x + 3x = 180
6x = 180
Solve for x
6x = 180
x = 30
Plug that into angle C
2(30) = 60
Angle C is 60 degrees
69 plus 13 because 30 plus 13 is 43, 43 plus 13 is 56, and you know the rest
