The length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches, find the dimensions of the rectangle
Answer:
length = 12
width = 9
Step-by-step explanation:
Let w= width of rectangle
length = w + 3
2w + 2(w + 3) = 42
2w + 2w + 6 = 42
4w = 36
w = 9 ( width of rectangle)
width = 9 inches
length = 9 + 3 = 12 inches

If h represents the hourly fee, which equation models this problem?
What was the hourly fee for the rototiller?
The hourly fee is $3.00 per hour.
It is required to find the hourly fee for the rototiller.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
Let h represents the hourly fee.
Let C be the total charge and t be the rental time in hours.
C = ht + 43
Putting the given values into the equation, we get:

Step-by-step explanation:
using addition to solve a fraction with the same base
step 1: take the denominator of both fractions and clear them from the equation

Larry Gold’s gross pay for this week as a stock clerk for Hensley’s is $375.15. He is single and claims 2 allowances. Using the percentage method of withholding, what is his withholding for federal income tax?
Larry gold is withholding $22.38 in federal tax income.
The federal government and the majority of states in the US impose income taxes.
Applying a tax rate to taxable income, which is the entire income less permissible deductions, yields the income taxes, which may rise as income rises. Income is a broad concept. Estates and trusts may be subject to taxation on income that has not been dispersed, in addition to individuals, corporations, and the government. (With a few exceptions for Federal income taxation) Partnerships are not subject to taxation; however, the partners of a partnership are. While nonresidents are solely subject to local taxes, residents and citizens are subject to worldwide taxes. Numerous credit kinds lower taxes, and some credit types may even be more than taxes before credits. There is an alternative tax.Given that Larry gross pay for this week is $375.15
Now we know from the income tax table that the withheld tax is calculated by calculating 6% of the gross pay when there are 2 allowances.
Tax = 6% of 375.15 = 22.38
Hence the withholding for federal income tax is $22.38 .

Hello, please help :) It’s about tables, I have ADHD trouble understanding as well (Please give explanation so I can understand)
a. 240 - 144 = 96 Adult males
260 - 129 = 131 Female children
b. 275-225 = 50 more children
c. 225/500 simplifies to 9/20 visitors are adults
d. 240:260
e. 144/500 chance that it is a male child
Okay so for a number 1 they want you to subtract the total from the child or adult. so for males, they want you to subtract 240 from 144. 240 - 144 equals 96 so there are 96 adults in males. moving on to the female we have to find how many children there are so, we have to subtract 260 from 129 which will equal 131. 131 is how many children are females.
For "B" we have to work out how many child visitors there are than adults. Easy we just have to subtract 275 from 225 which will equal 50!
Now for question C, we have to write the adult total in the lowest term what they mean by that is a fraction said to be written using the lowest terms if its numerator and denominator are relatively prime, that is, they have no common factors other than 1. So the lowest term for the adult is 9/4
Now for question D, they want us to make a ratio for the number of males and for the number of females. A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. The ratio for the male is 96:144 (for every 96 adults there are 144 children) The ratio for females is 129:131 (for every 129 female there are 131 children)!
For E it is a probaIlity that there is a 144/500 chance there's a male child! Not much I can explain for E because that's a hard one but that's the answer for E

The additional of a triangle's degree measure will always equal 180˚
When the question asks you if a triangle with 112˚, 57˚, and 11˚, you have to add them up and make sure they equal to 180˚
In this case, 112˚ + 57˚ + 11˚ DO add up to 180˚, and is indeed a triangle.

x² - 9 / х^2 - 3x
Answer:
[tex]\frac{x+3}{x}[/tex]
Step-by-step explanation:
Factorise numerator and denominator
x² - 9 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
x² - 9
= x² - 3² = (x - 3)(x + 3)
x² - 3x ← factor out x from each term
= x(x - 3)
Then
[tex]\frac{x^2-9}{x^2-3x}[/tex]
= [tex]\frac{(x-3)(x+3)}{x(x-3)}[/tex] ← cancel common factor (x - 3) on numerator/denominator

Answer:
6.5 rounded from 6.53...
to see if this is correct we can:
13.5+9.5+6.5*3 = 42.5
but since we rounded it we can say its 6.5
Answer:
6.55 meters each day
Step-by-step explanation:
You know that in the end the fence must be 42.6 meters long.
On Monday & Tuesday, he installed 22.95 meters of fence. (We know this because 13.45 + 9.5 = 22.95).
So, how much is left? You find that by subtracting 22.95 from 42.6.
42.6-22.95 = 19.65 meters
There are 3 days left of fencing, and these days he will install equal lengths, so you can divide 19.65 meters by 3 days.
19.65 / 3 = 6.55 meters of fence per day

b=5
therefore y = 5
Answer: y = -2x - 1
Step-by-step explanation:
We can calculate the slope from the two given points. Slope is the change in y per the change in x, sometimes called the rise (y) over the run (x)
Rise is (-9 -3) = -12
Run is (4 - (-2)) = 6
Slope = Rise/Run = -12/6 = -2
The line is y = -2x + b
Find b by using either of the two known points (solutions). I'll choose (-2,3) [because I like smaller numbers]
y = -2x + b
3 = -2*(-2) + b
b = -1 [That was only slightly easier than -9 = -2*(4) + b; b = -1]
The equation is y = -2x - 1
