William says that 15 years from now, his age will be 3 times his age 5 years ago. if x represents William's present age, what equation represents his claim? What is Willaim's current age?
Answer:
x + 15 = 3 (x - 5)
William’s current age: 15. Years old
Step-by-step explanation:
x + 15 = 3(x-5)
x + 15 = 3x - 15
15 + 15 = 3x - x
30 = 2x
x = 15

Write an equation of the line with the given slope and y-intercept 1.slope=7;y-intercept=2 2.slope 1/3;y-intercept =-1
Answer:
1. y = 7x + 2
2. y = 1/3x - 1 or 3y = x - 3
Step-by-step explanation:
Use this formula y = mx + b where the slope is represent by "m" and the y-intercept is represent by "b"
1. y = mx + b
y = 7x + 2
2. y = mx + b
y = 1/3 x + (-1) Let clean this up by multiplying each term by 3
3y = 1x - 3 or 3y = x - 3

Write the null and alternative hypothesis which would pertain to a hypothesis test described in each scenario last year politicians average 2000 trouble hours this year with an election occurring it is expected that they will travel more hours
Considering the situation given, it is found that:
The null hypothesis is [tex]H_0: \mu = 2000[/tex]The alternative hypothesis is: [tex]H_1: \mu > 2000[/tex].At the null hypothesis, we test if they average the same amount of trouble hours as last year, that is, of 2000 trouble hours, thus:
[tex]H_0: \mu = 2000[/tex]
At the alternative hypothesis, we test if this amount has increased, that is:
[tex]H_1: \mu > 2000[/tex]

Ms. Dirr is selling her car to her sister. The original price of the car was $24,179 and
each year the car decreasing (goes down) by $3000. Write a function rule where C =
value of the car and y = number of years
O C = 3000 - 24179y
O C = 24179 - 3000y
O C = 3000 + 24179y
OC - 24179 + 3000y
Answer: 24,179 - 3000y
Step-by-step explanation: Each year the car goes down by 3000 since you said it was decreasing, so y represents the year and you eould out it next to the 3000 to represent that 3000 is being decreased every year.
What is the rate of return when 35 shares of Stock A, purchased for $20/share, are sold for $815? The commission on the sale is $6. Rate of Return = [?] % Give your answer as a percent rounded to the nearest tenth
Cost price:-
[tex]\\ \sf\longmapsto 35\times 20[/tex]
[tex]\\ \sf\longmapsto 700[/tex]
Commision=$6Total sold price=815+6=823$Now
Return=823-700=123
Rate of return
[tex]\\ \sf\longmapsto \dfrac{123}{700}\times 100[/tex]
[tex]\\ \sf\longmapsto \dfrac{123}{7}[/tex]
[tex]\\ \sf\longmapsto 17.5\%[/tex]
The rate of return on the stock will be equal to 17.3%.
What is the Percentage?The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.
As per the given information in the question,
Total number of stocks = 35
Purchase price of each stock = $20
Then, the price of 35 stocks will be,
35 × $20 = $700
The selling price of all stocks = $815
Also, the commission for selling is $6.
So, the extra money earned will be,
815 - 700 + 6 = 115 + 6
= $121
So, the rate of return from the original price will be,
= 121/700 × 100
= 12100/700
= 17.3%

x over 32 = 3 over 16
Answer:
7/32 = 3/16
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
We simplify the equation to the form, which is simple to understand
x/32=3/16
Simplifying:
+ 0.03125x=3/16
Simplifying:
+ 0.03125x=0.1875
We move all terms containing x to the left and all other terms to the right.
+ 0.03125x=0.1875
We simplify left and right side of the equation.
+ 0.03125x=0.1875
We divide both sides of the equation by 0.03125 to get x
