Rmember you can do anything to an equaiton as long as you it to both sides
also
x-x=0
and
x times 1/x=1
and x times 1=x
16+2.4c=22.5
subtract 16 from both sides
2.4c=6.5
multiply both sides by 1/2.4
1c=2.708333333333333
Answer:
Step-by-step explanation:
we know that the total time of the show is 30 minutes.
commercial part = 3x+2
entertainment part = y
also we know that y = 3x +2
y + 3x+2 = 30
we can also say that
2(3(x) +2) = 30
so then
6x +4 = 30
6x = 26
x = 4
4
is the time in minutes for commercials

Answer:
Step-by-step explanation:
It is given that the regression equation

predicts an adult’s height (y) given the individual’s mother’s height (x1), his or her father’s height (x2), and whether the individual is male (x3 = 1) or female (x3 = 0).
The coefficient of x1 = 0.32 represents the increase in height of the child due to one inch increase in mother.
Similarly coefficient of x2 = 0.42 represents the increase in height of the child due to one inch increase in father.
and coefficient of x3 = 5.31 represents the increase in height of the child due to being a male than a female.
Answer:

Step-by-step explanation:
In a right triangle the tangent of an angle is the ratio of the opposite length over the adjacent*. In formulas,
Solving for x, using a calculator for the tangent, 
*I promise I didn't just spellcheck that.
