This would produce a geometric sequence of the form:

g=3(2.2)^(n-1)

The sum of which is:

g=3(1-2.2^n)/(1-2.2) cleaning up a bit...

g=-3.6(1-2.2^n)

g(15)=-3.6(1-2.2^15)

g(15)=492764.6, since the number of geese must be an integer...

g(15)=492764

1. General Trades A roofer earns $24 per hour plus $36 per hour overtime. If he puts in 40 hours of regular time during a certai
snow_tiger [21]

Answer:

He should work 6\frac{2}{3} hours in overtime.

Step-by-step explanation:

Let x represents the number of hours of regular time and y represents the number of hours of overtime,

Since, earnings are $24 per hour for regular time and $36 per hour for overtime,

Thus, total earning = (24x + 36y) dollars,

Here, x = 40 hours and total earning = $ 1200,

By substituting the values,

1200 = 24(40) + 36y

1200 = 960 + 36y

240 = 36y

⇒ y = 6\frac{2}{3}\text{ hours}

Hence, he should work 6\frac{2}{3} hours in overtime.

What is the order of the steps to solve for x in the equation 3x - 6x - 7 = 29?
Anna35 [415]

Answer:

3x - 6x - 7 = 29 <u>Given</u>

<u>-----------------------------------</u>

3x - 6x -7  = 29

           + 7   + 7     <u>Addition property of equality</u>

3x - 6x = 36

<u>--------------------------------------------------------------</u>

3x - 6x = 36

<u>(</u>3x + -6x) = 36         <u>Combine like terms</u>

-3x = 36    

<u>--------------------------------------------------------------</u>

-3x = 36

(-3x = 36)/ -3         <u>Division property of equality</u>

x = -12

<u />

Step-by-step explanation:

I tried to seperate the steps so you can go through them. First you had to add on both sides to take out the like terms, then combine the 3x and the  -6x to make -3x (easier to look at and divide), and finally divide to find X. the end product using X cannot be a negative because its a filler space for a real number.

Hope this helps :)
