Answer:
B
Step-by-step explanation:
If you look at A and you subtract 3x by 4x you get x and you subtract 3 from -7 and you get -10. But if you look at B you do the stuff in the parentheses first and you get 4x+12x+28=16x+28 and they're the same so it's B.
Answer:
y= 3/5x - 1
+1 +1
y+1 = 3/5x
((y+1)5) = 3x
divide by 3 both sides
x= (y+1)5 / (3)

Answer:
30%
Step-by-step explanation:
If Justin has a 20% chance and Cam has a 50% chance that adds up to 70%

70 - 100 = 30

Answer:
C. 31 units
Step-by-step explanation:
Circumference of a circle is the distance around the circle and is given by C = pi•d
Your circle with a point and center given has a radius of 5 because from (2,1) to (7,1) is 5 units. Radius 5 means the diameter is 10.
C = pi•10
= 3.14•10
= 31.4 using 3.14 as an approximation for pi.
Circumference is approximately 31 units.
