we have
6x+7y=4x+4y
we figure out that
the solution is ----> (x,-4)
substitute the value of y=-4 in the equation
6x+7*(-4)=4x+4*(-4)
6x-28=4x-16
Combine like terms
6x-4x=28-16
2x=12
x=12/2
x=6
So the the missing value is x=6.
Answer:
Option 1
Step-by-step explanation:
P(glasses' ^ internet) = 3/20 = 0.15
P(glassses') = 8/20 = 0.40
P(internet) = 7/20 = 0.35
(0.40×0.35) = 0.14
I believe the answer is P = 2.4

Step-by-step explanation:
Answer:
20π
Step-by-step explanation:
Area = πr^2
100π = πr^2
solve for r and r = 10
circumference of a circle is 2πr
therefore 2π×10=20π in
