Answer:
If you are solving the equation for x :
3x + 3y = 180
3x = -3y + 180
x = -y + 60 or x = 60 - y
If you are solving the equation for y:
3x + 3y = 180
3y = -3x + 180
y = -x + 60 or y = 60 - x

A clothing store features Shirts and Pants in the ratio of 3:6. There are 42 more Shirts than pairs of pants. How many articles of clothing are in the store?
Answer:
126
Step-by-step explanation:
The ratio of shirts to pants = 3:6. Which also equals 1:2.
Let the pairs of pants = t
Since there are 42 more shirts than pair of pants, shirts = t + 42
Number of pairs of pants is t.
Number of shirts = (t + 42)
The number of the pairs of pants is 42.
The number of shirts is 84.
Total number of clothings is 126.

What is plane?In geometry, a plane is a flat surface that extends into infinity. It is also known as a two-dimensional surface. A plane has zero thickness, zero curvature, infinite width, and infinite length. It is actually difficult to imagine a plane in real life; all the flat surfaces of a cube or cuboid, flat surface of paper are all real examples of a geometric plane. We can see an example of a plane in which the position of any given point on the plane is determined using an ordered pair of numbers or coordinates. The coordinates show the correct location of the points on the plane.
As, per the figure we can say that the upper plane is made of plane ABCD.
So, among all the option BCD will be correct because BCD is part of ABCD.

Divide 8x3 by 2x.
Divide 2x by 8x3.
Divide 6x by 2x.
Divide 2x by 6x.
Answer:
Divide 8x^3 by 2x
Step-by-step explanation:
Here, we want to identify the first step to take in the polynomial division.
When working with a polynomial division, what to do is to divide the first term of the dividend by the first term of the divisor ( the divisor is arranged in descending powers of x)
The number we want to divide is the dividend, while the number we are using to divide is the divisor.
In this case, the first term of the dividend is 8x^3 while that of the divisor is 2x
The first step of the following division problem is to divide 8x³ by 2x
How to divide polynomialsGiven:
(8x³ – x2 + 6x + 7) ÷ (2x – 1)
(8x³ – x2 + 6x + 7) is the divided
(2x – 1) is the divisor

Assume the Ziders continue to grow in the same pattern. How old would a Zider be that had 73 hairs?
Number of hairs in day 1 , a = 5.
Every day number of hairs increases by , d = 4.
So, it is an Arithmetic Progression with first term a = 5 and common difference d = 4.
So, number of hair in nth days is given by :
[tex]a_n=a+(n-1)d\\\\a_n=5+(n-1)4[/tex]
Let, after x days number of hairs are 73.
[tex]73=5+(x-1)4\\\\x-1=\dfrac{73-5}{4}\\\\x=18\ days[/tex]
Therefore, Zider is 18 days old.
Hence, this is the required solution.

I went to Half Priced Books and purchased 15 books. I paid $2 each for some and $3 each for the rest of the books. How many $2 books did I buy if I spent $34?
Answer:
Thus the number of books at $2 is 9 books.
Step-by-step explanation:
The number of the book purchased = 15 books
Total amount spend to buy the books = $34
The prices of books are $2 and $3.
Let the number of books purchased at price $2 = x
Let the number of books purchased at price $3 = y
Now we have to find the number of books that is bought at $2.
Below are the equations.
x + y = 15
2x + 3y = 34
Now solve for the x,
x + y = 15
y = 15 – x
Now insert it in the 2x + 3y = 34
2x + 3(15-x) = 34
2x + 45 – 3x = 34
-x = 34 – 45
x = 9
Thus the number of books at $2 is 9 books.
which of these numbers is between 2 and -3 on the number line

Answer:
5. x = 13
6. x = 11; y = 3
Step-by-step explanation:
5. (9x + 2)° = 119° (alternate interior angles are congruent)
[tex] 9x + 2 = 119 [/tex]
Subtract 2 from each side
[tex] 9x + 2 - 2 = 119 - 2 [/tex]
[tex] 9x = 117 [/tex]
Divide both sides by 9
[tex] \frac{9x}{9} = \frac{117}{9} [/tex]
[tex] x = 13 [/tex]
6. (9x + 25)° = (13x - 19)° (corresponding angles are congruent)
[tex] 9x + 25 = 13x - 19 [/tex]
Collect like terms
[tex] 9x - 13x = - 25 - 19 [/tex]
[tex] -4x = -44 [/tex]
Divide both sides by -4
[tex] \frac{-4x}{-4} = \frac{-44}{-4} [/tex]
[tex] x = 11 [/tex]
(13x - 19)° + (17y + 5)° = 180° (linear pair)
[tex] 13x - 19 + 17y + 5 = 180 [/tex]
Plug in the value of x and solve for y
[tex] 13(11) - 19 + 17y + 5 = 180 [/tex]
[tex] 143 - 19 + 17y + 5 = 180 [/tex]
Collect like terms
[tex] 129 + 17y = 180 [/tex]
Subtract 129 from both sides
[tex] 129 + 17y - 129 = 180 - 129 [/tex]
[tex] 17y = 51 [/tex]
Divide both sides by 17
[tex] \frac{17y}{17} = \frac{51}{17} [/tex]
[tex] y = 3 [/tex]
5) through: (-3, 3), slope = 0
Answer:
3
Step-by-step explanation:
We know that -3 is on the x axis and 3 is on the y axis.
and the y axis usually determines if you are going to have a positive slope or negative since it would either rise or decrease. In this cause (-3, 3) shows that 3 is going to be our slope.
Answer:
y=3
Step-by-step explanation:
In a normal equation, y=mx+b, m=slope. If slope=0 in this equation, then it is safe to say that the equation is y=b. Since the Y coordinate is 3, then we can safely assume that the equation is equal to y=3

Please help. What is the slope for #2?
Answer: -4
Step-by-step explanation:
To find the slope, you want to use the slope formula [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. You can use any two points to solve. Let's use (-2,3) and (-1,-1).
[tex]m=\frac{-1-3}{-1-(-2)} =\frac{-4}{1} =-4[/tex]
Another way to tell is by looking at the arrows with a -4 written next to it. That also tells you what the slope is.
