X=-3 because first substitute the value of y into the original equation -2x-3=x+6 then isolate the variables -2x-x=6+3 which is -3x=9 then we can divide x=9/-3 which =-3
Answer:
Circumference = 65.97344573
Step-by-step explanation:
Given the diameter of a circle, we can use the formula C = πd to find the circumference.
C = circumference
π = pi
d = diamater
Equation: 21(π) = 65.97344573
Make sure to round to whatever decimal place is asked for!
Answer:
129
Step-by-step explanation:
None
Probability is defined as the ratio of the successful
events over total events. In this case an event is described as the color of
block.
The total number of blocks present in the bag is:
total blocks = 36 + 48 + 22 + 19
total blocks = 125
So calculating for each theoretical probability:
P (green) = 48 / 125 = 0.384
P (not yellow) = P (red or green or purple)
P (not yellow) = (125 – 22) / 125 = 0.824
P (yellow or not green) = P (yellow or red or purple)
P (yellow or not green) = (125 – 48) / 125 = 0.616
