Answer: The mechanic worked for 4.25 hours for the fourth customer.
First find out the slope.
Y^2-y^1/x^2-x^1
210-90/3-1=60
Slope: 60
Then find out what the y-intercept is by plugging in values we know into y=mx+b
90=60(1)+b
30=b
Y=60x+30
Substitute the y with 285 to find out the x (hours)
285=60x+30
4.25=x

Answer:
$126,980
Step-by-step explanation:
Given the equation C = 2.32N + 34,180 where 'C' is the cost of raising a child and 'N' is the income. If the Corlone family has an income of $40,000, you can use this value for 'N' and solve for 'C':
C = 2.32(40,000) + 34,180
C = 92,800 + 34,180
C = $126,980
Answer:
8 x = 60.10251159
9 x = 3.66062978
Step-by-step explanation:
Hey There!
So to answer these questions we need to use the Law of sines
Consider the following image
So to find x in number 8 we setup an equation
now we solve for x
step 1 multiply each side by sin 90
now we have
if you plug the equation in a calculator you get that
x=60.10251159
<u>( make sure if it says to round to the nearest.... that you round before entering your answer)</u>
For number 9 the equation would be
now we solve for x
step 1 multiply each side by sin 24
now we have
if you plug this into a calculator you get that
x = 3.66062978
<u>(once again if it says to round to the nearest... make sure you round before you put in your answer.)</u>
Answer:
x = 10
Step-by-step explanation:
7x-25 = x + 35
Subtract x from each side
7x-x-25 = x-x + 35
6x -25 = 35
Add 25 to each side
6x -25+25 = 35+25
6x = 60
Divide each side by 6
6x/6 = 60/6
x = 10
