When the sum of twice a number and 4 is tripled the result is 72?

1 answer:

7 0

The unknown value can be called x.
3(2x +4) = 72
6x +12 = 72
72 - 12 = 6x
6x = 60
x = 6x / 6
x = 10

Hope This Helps You!
Good Luck Studying :)

Plutonium-240 decays according to the function where Q represents the quantity remaining after t years and k is the decay consta

taurus [48]

Note: a radioactive decay constant is always negative.

time = [natural log(ending amount / beginning amount)] / k
time = ln (20 / 24) / -.00011
time = ln (5/6) / -.00011
time = -.018232155683 / -.00011
time = 165.7468698455 
time = 165.75 years

Answer:

Let R be the greater radius and r be the smaller radius

A) Area of the sidewalk = R^2 - r^2 - This can be the expression

B) = 3.14

=(R^2-r^2)

=(11^2-9^2)

=(121-81)

=*40

That was the simplified expression

Answer = 3.14 * 40 = 125.6m^2

Given Equation: y=5x-1

as we know that the y intercept have, x coordinate(absicasse) equal to 0

so,put x=0 to get y intercept

i.e, y =5×0 -1

i.e, y= -1
