Answer:

x = 7

Step-by-step explanation:

(4x + 2) \degree = 360 \degree - (85 + 40 + 75 + 130) \degree \\  \\ (4x + 2) \degree = 360 \degree - 330 \degree \\  \\ (4x + 2) \degree = 30 \degree \\  \\ 4x + 2 = 30 \\  \\ 4x = 30 - 2 \\  \\ 4x = 28 \\  \\ x =  \frac{28}{4}  \\  \\ x = 7

I have hard prolems on subtract 4.000 -6.000
anyanavicka [17]
6.000 - 4.000 = 2.000

It is a very simple equation. The easiest way to remember it would be to look at the first two numbers. 6 subtract 4 equals 2. So when you see this equation, simply for starters do 6 subtract 4, which equals 2, and then add a decimal place and the 3 zeros at the end. Does that make sense? Please let me know whether this was useful to you or not, and if you have any further questions please feel free to ask so on comments. Thank you!

For two days, your boss decides to double the amount you make if on day 1, you make $70 dollars and on day 2, you make$80 dollar
Hoochie [10]

Answer:

300

Step-by-step explanation:

Day 1: $70

Day 2: $80

Total commission = day 1 × 2 + day 2 × 2

= 70 × 2 + 80×2

= 140 + 160

= 300

Or

Total commission = 2(day 1 + days 2)

= 2(70 + 80)

= 2(150)

x = 300

Can someone please tell me if i am right?
pentagon [3]
Second one is correct, that is an identity.

Third one is a contradiction:
6x - 15 = 3 * (2x - 6)    ------>    6x - 15 = 6x - 18

Fourth one:
5x - 3 * (x - 4) = 2 * (x - 6) ---> 5x - 3x + 12 = 2x - 12 ---> 2x + 12 = 2x -12
So this is a contradiction as well.
