Step-by-step explanation:
Answer:
x = -5
Step-by-step explanation:
0.2x-8=0.4x-7
First, add 8 to both sides.
0.2x-8+8=0.4x-7+8
0.2x=0.4x-1
Next, subtract 0.4x from both sides.
0.2x-0.4x=0.4x-1-0.4x
-0.2x=1
Divide both sides by -0.2:
-0.2x/-0.2=1/-0.2
x=-5
Answer:
The angle = 144 degrees.
Step-by-step explanation:
Look at it this way (it is a proportion question)
30 people would require a pie chart made of a full circle (360 degrees)
12 people would require x part of the pie chart.
30/360 = 12 / x Cross multiply
30x = 360 * 12 Simplify the right
30x = 4320 Divide by 30
30x/30 = 4320/20
x = 144 Answer
I believe your answer is C
