Answer:
15w+5
Step-by-step explanation:
Any like terms can be combined to simplify.
2w+13w=15w
4+1=5
So, 2w+4+13w+1= 15w+5
Answer:
W = -1/3
Step-by-step explanation:
15W + 5= 0
15W = -5
W = -5/15

Which equation shows how the distributive property can be used to find the number of
Xs in both arrays?
Answer:
here is a simple version
lets make A equal the exponent so (A=^2 or 3 or whatever)
the exponent will be the amount of times you want to repeat the process.
Now lets make x = the first array, so x=3
and lets make y = the second array, y=7
now a simple equation would be (3x)(7y)^A or for this you could say
(3x)(7y)^6

Answer:
$29.14
$86.68
Step-by-step explanation:
$30 before tax
Discount: 20%
100% - 20% = 80% = 0.8
0.8 * $30 = $24 after discount
Tax: 6.4%
100% + 6.4% = 106.4% = 1.064
1.604 * $24 = 25.54 after tax and discount
Tip: 15% = 0.15
0.15 * $24 = $3.60
Total = $25.54 + $3.60 = $29.14
$75 before tax
10% discount
100% - 10% = 90%
90% of $75 = 0.9 * $75 = $67.50 after discount
Tax: 7%
100% + 7% = 107% = 1.07
1.07 * $67.5 = $72.23 after discount and tax
Tip: 20% = 0.2
0.2 * $67.50 = $13.50
Total = $72.23 + $13.50 = $85.73

Lauren Rodriguez earns $8.35 per hour as a swimming instructor. How many hours per week must she work if she wants to earn approximately $190.00 per week?
Answer:
22.75 hours per week
Step-by-step explanation:
We can see from the question that the target amount of money is $190.00 per week.
If Lauren Rodriguez earns $8.35 in one hour
then $190.00 will be earned in x hours
8.35x = 190.00
x = 190.00/8.35
x = 22.75 hours per week

Raul works at a movie theatre. The function f(x) represents the amount of money Raul earns per ticket, where x is the number of tickets he sells. The function g(x) represents the number of tickets Raul sells per hour, where x is the number of hours he works. Show all work to find f(g(x)), and explain what f(g(x)) represents.
[tex]f(x)=2x^2+16\\g(x)=\sqrt{5x^{3} }[/tex]
Answer:
Part 1)
[tex]f(g(x))=10x^3+16[/tex]
Part 2)
The composition f(g(x)) represents the amount of money Raul earns per ticket given the amount of hours Raul works
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=2x^2+16[/tex]
Which represents the amount of money Raul earns per ticket and:
[tex]g(x)=\sqrt{5x^3}[/tex]
Which represents the number of tickets Raul sells per hour.
Part 1)
We want to find f(g(x)).
So, we substitute g(x) for f(x). This yields:
[tex]f(g(x))=2(\sqrt{5x^3})^2+16[/tex]
This can be expanded a simplified as such:
[tex]f(g(x))=2((\sqrt{5})^2(\sqrt{x^3})^2)+16=10x^3+16[/tex]
Part 2)
Recall that f(x) outputs the amount of money Raul earns per ticket.
And g(x) inputs the amount of hours Raul works.
When we composed f(g(x)), the input and output stayed the same.
So, f(g(x)) represents the amount of money Raul earns per ticket (output of f(x)) given the amount of hours Raul works (input of g(x)).
Answer:
The composition f(g(x)) represents the amount of money Raul earns per ticket given the amount of hours Raul works

2 1 Add the expressions 4- b +-a and a +-6-7. What is the simplified sum? 3 4 2 6 14 5 Q+b-3 6 3 1 b-3 2 4 3 5. a+2b-3 4 6 5 1 -6-3 6 12
Answer:
-b - 9
Step-by-step explanation:
First, since the a cancel eachother out we are left with (4-b) + (-6-7)
Second, you want to add the -6 and -7 to get -13, so (4-b) - 13
Finally, add the 4 to the negative 13 to get (-b - 9)

A car was bought for £18,000.
It was sold for £15,300.
Express this as a percentage decrease.
Answer:
15%
Step-by-step explanation:
when 18000 is 100%, 10% is 1800. So to make 15300 we need 8.5 1800s. So 85% of 18000 is 15300 so the rest is 15%. The answer is 15%
Answer:
15%
Step-by-step explanation:
[ (18,000-15,300) / 18,000 ] x 100
= (27,00 / 18,000) x 100
= 0.15 x 100
= 15%

the following m and m colors are in the bowl
4 yellow
6 orange
3 green
5 blue
2 brown
what is the probability of selecting a blue eating it then selecting a yellow
Answer:
probability of blue =5/20=1/4
Step-by-step explanation:
probability of yellow=4/20=1/5
Probability of selecting a blue colour then a yellow colour is, 1/19.
What is conditional probability?Conditional probability is a term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.
Given, A bowl containing 4 yellow, 6 orange, 3 green, 5 blue, 2 brown colors.
Let P(A) be the probability of selecting a blue colour.
∴ P(A) = N(B)/N(S).
P(A) = 5/20.
P(A) = 1/4.
Let P(B) be the probability selecting a yellow colour is = 4/19.
As we replacement is not allowed.
∴ Probability of selecting a blue colour then a yellow colour is,
= P(B)×P(A).
= 4/19×1/4.
= 1/19.
