The perimeter of a rectangle is 28 inches. The length is 6 less than 3 times the width. What is the length of the rectangle?
Answer: The length is 9 inches.
Step-by-step explanation:
L = 3w - 6 (the length is 6 less than 3 times the width).28 = 2(3w - 6) + 2w (plug in width and length --> multiplied by 2 because of perimeter).28 = 6w - 12 + 2w (distribute)28 = 8w - 12 (combine like terms)40 = 8w (add 12 to both sides)5 = w <-- widthFind the length:
L = 3w - 6L = 3(5) - 6L = 15 -6L = 9 inAnswer:
The length is 9.

Answer:
Hi, this is a strange problem but I believe the answer is A) 4x-3.
Step-by-step explanation:
I think the X symbols represent "X"es and the dashes represent single negative digits. I may be wrong, but I think this is what your teacher is most likely looking for. Good luck! :)
I have a bag with yellow and blue marbles in it. At the moment, the ratio of blue marbles to yellow marbles is 4:3. If I add 5 blue marbles and remove 3 yellow marbles, the ratio will be 7:3. How many blue marbles were in the bag before I added more?
Answer:
4:7 7 being to total number of marbles (part to whole ratio)
There are 16 blue marbles were in the bag before I added more.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
Given that;
The ratio of blue marbles to yellow marbles is 4 : 3.
And, If I add 5 blue marbles and remove 3 yellow marbles, the ratio will be 7:3.
Now,
Since, The ratio of blue marbles to yellow marbles is 4 : 3.
Hence, Number of blue marbles = 4x
Number of yellow marbles = 3x
And, If I add 5 blue marbles and remove 3 yellow marbles, the ratio will be 7:3.
Then, We can formulate;
⇒ 4x + 5 / 3x - 3 = 7x / 3x
⇒ (4x + 5) / (3x - 3) = 7 / 3
⇒ 3 (4x + 5) = 7 (3x - 3)
⇒ 12x + 15 = 21x - 21
⇒ 15 + 21 = 21x - 12x
⇒ 36 = 9x
⇒ x = 4
Thus, The number of blue marbles = 4x
= 4 × 4
= 16

Emily Elizabeth has $1.50 in dimes and nickels. She has 22 coins in all. How many nickels does she have?
Answer:
[tex]14[/tex]
Step-by-step explanation:
We can set up the following system of equations:
[tex]\begin{cases}10d+5n=150\\d+n=22\\\end{cases}[/tex], where [tex]d[/tex] is the number of dimes she has and [tex]n[/tex] is the number of nickels she has.
Multiplying the second equation by -5 and adding both equations lets us isolate and solve for [tex]d[/tex]:
[tex]10d+5n+(-5(d+n))=150+(-5(22)),\\5d=40,\\d=8[/tex]
Plugging [tex]d=8[/tex] into any of the two equations will let us solve for [tex]n[/tex]:
[tex]8+n=22,\\n=\fbox{$14$}[/tex].
Therefore, she has 14 nickels.

Answer:
Step-by-step explanation:
AB BC AC
(I’m not sure, If Im wrong let me knoww ❤️❤️)
Answer:
AC BA BC shortest to longest.
Step-by-step explanation:
All triangles have 180o in their interior angles. So A + B + C = 180
5x - 4 + 2x + 3 + 3x - 9 = 180 Combine the like terms on the left.
10x - 10 = 180 Add 10 to both sides
10x - 10 + 10 = 180 + 10
10x = 190
x = 190/10
x = 19
So <A = 5x - 4 = 91
<B = 2x + 3 = 41
<C = 3x - 9 = 48
Total 180
So the largest Line is opposite 91 and it is BC
The Middle sides line is opposite 48 and it is BA
The smallest line is opposite 41 and it is AC
AC BA BC shortest to longest.
I'm not sure what AAS,SAS,SSS,ASA mean .how do I solve this?
Answer:
AAS is an acronym for Angle-Angle-Side. It basically means that if two angles and a nonincluded side of one triangle are congruent to two angles and the corresponding nonincluded side of a second triangle, then the two triangles are congruent. SAS is an acronym for Side-Angle-Side. It means that if two sides and the included angle of one triangle are congruent to two sides and the included angle of a second triangle, then the two triangles are congruent. SSS is an acronym for Side-Side-Side. It means that if three sides of one triangle are congruent to three sides of a second triangle, then the two triangles are congruent. ASA is an acronym for Angle-Side-Angle. It means that if two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the two triangles are congruent.
In the problem, we know that the corresponding sides of both triangles are congruent to each other, so those would be given. The third side of each triangle would also be congruent because of reflexive property. Reflexive property means that the two triangles share a line segment. So, the answer would be SSS.

Eli is deciding between two landscaping companies for his place of business. Company A charges $25 per hour and a $300 equipment fee. Company B charges $50 per hour and a $125 equipment fee. Let AA represent the amount Company A would charge for tt hours of landscaping, and let BB represent the amount Company B would charge for tt hours of landscaping. Write an equation for each situation, in terms of t,t, and determine which company would be cheaper if Eli needs 5 hours of landscaping.
Answer:
Company B will charge cheaper in 5 hours
Step-by-step explanation:
Step one:
Given data
Company A
charges $25 per hour and a $300 equipment fee
let the total be
A= 300+25t---------------1
Company B
charges $50 per hour and a $125 equipment fee.
let the total be
A= 125+50t---------------2
put t = 5 in the two expressions above
A= 300+25t---------------1
A= 300+25*5
A=300+125
A=$425
B= 125+50t---------------2
B= 125+50*5
B=125+250
B=$375
Answer:
A = 25t + 300 B = 50t + 125
company B is $50 cheaper than company A for 5 hours of landscaping

Convert -4x+y=5 to slop intercept form
Answer: -4x + y = 5 in slope intercept form is 4x + 5
Answer: y= 4x + 5
Step-by-step explanation:
The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y = mx + b
Rewrite in slope-intercept form.
Add 4x to both sides of the equation.
y = 5 + 4x
Reorder 5 and 4x.
y= 4x + 5

Answer:
1) Actual cost was $5,762.50
2) Joe's birthday is on January 1st.
Step-by-step explanation:
1) To find this, since we know they were wrong by an identical amount and one was over and the other was under, we can average the cost to find the difference between the amounts. Then we can add that difference to the lower (or subtract it from the higher) amount:
6950 - 4575 = 2375
2375 / 2 = 1187.50
4575 + 1187.50 = $5,762.50
2) Joe could turn 21 on January 1st, but was 20 on December 31st. Next year Joe would turn 22 on January 1st.
I hope this helps!

Terms are separated by addition or subtraction signs.There are three parts separated by two addition/subtraction signs.That means there are three terms.Number 2 Explanation:
Polynomials can't have negative exponents.Polynomials can't have fractional exponents on variables or roots of variables.For the first option, [tex]\frac{1}{x}[/tex] can also be written as [tex]x^{-1}[/tex], so it has a negative exponent and is not a polynomial.The second and third options follow polynomial rules.The fourth option has [tex]x^{\frac{1}{2} }[/tex], which is the same thing as [tex]\sqrt{x}[/tex]. Polynomials can't have roots of variables (or fractional exponents on variables), so this isn't a polynomial.Zohad has $30 in a savings account that earns 15% interest per year.
