Answer:
Equation: 139 + 3x + (5x - 10) + (10x - 9) + 3x = 540 (not simplified, see below for simplified)
x = 20
Step-by-step explanation:
If the sum of the angles is 540°, then that means you add them up to get 540°.
139 + 3x + (5x - 10) + (10x - 9) + 3x = 540
129 + 8x + (10x - 9) + 3x = 540
120 + 18x + 3x = 540
120 + 21x = 540
21x = 420
x = 20

First, let's add the two from both sides.
y + 2 = 3x - 2 + 2
y + 2 = 3x
Now, all we have to do is to divide both sides by 3.
(y + 2)/3 = (3x)/3
(y + 2)/3 = x
And now, flip both sides around so it looks nicer.
x = (y + 2)/3

Step-by-step explanation:
Answer:
16
Step-by-step explanation:
80 divided by 5 equals to 16.
You divide by 5 because Since he sold 80 this week and last week was 5 times less.
