Linear Pair means two angles add to 180. They have a base and a transversal in common.
Equation
1/3(27x - 6) + 1/2(6x - 20) = 180 Remove the brackets
Solution
9x - 2 + 3x - 10 = 180 Collect like terms
12x - 12 = 180 Add 12
12x - 12 + 12 = 180 + 12 Combine
12x = 192 Divide by 12
12x/12/ = 192/12
x = 16
Laurel is a huge fan of hats, she likes all kinds of hats and recently started collecting them. She already owns 3 hats. She plans on buying a hat according to the season every month. Based on this information answer the following Questions.
What is the linear function?
Answer:
y=3+x
Step-by-step explanation:
If you are ever unsure about how to proceed with a math problem, one thing I find very helpful is to imagine the scenario and sub in the numbers. That's always helped me
At the very beginning, when
x=0, Laurel hasn't bought any new hats yet, she owns 3 hats, so y=3.
After the first month, when x=1, laurel owns 3 hats, plus the 1 hat she just bought. She now owns y=3+1 hats.
After the second month, when
x=2, laurel owns 3 hats, plus the 2
new hats she bought after she started collecting hats. She now owns y=3+2
hats.
Now, we can write the function.
y=3+x

Using proportions, it is found that:
a. The equations are:
1. 24x+28(5-x)=132.4. 24(5-x)+28x=132.b. You would have saved $8 by switching the colors of the dining room and living room.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For item a, considering that 5 cans were bought, there are two options:
x cans of white paint and 5 - x cans of blue paint.5 - x cans of white paint and x cans of blue paint.Hence the equations are given by:
1. 24x+28(5-x)=132.4. 24(5-x)+28x=132.The solution for x is given by:
120 - 24x + 28x = 132
3x = 12
x = 4.
Considering the possible solution, of 4 cans of blue paint and 1 can of white paint.
Exchanging the colors, the price would be of:
4 x 24 + 1 x 28 = 124.
132 - 124 = $8.
You would have saved $8 by switching the colors of the dining room and living room.

Stefanie bought a package of pencils for $1.75 and some erasers that cost $0.25 each. She paid a total of $4.25 for these items, before tax.
Exactly how ,any erasers did stefanie buy?
Answer:
(4.25-1.75)/0.25=10
she bought 10 erasers
Answer:
10 Erasers
Step-by-step explanation:
We can establish the following equation:
TP = NP*PP + NE*EP
Where:
TP = Total price; (4.25)
NP = Number of pencil packages; (1)
PP = Pencil Package's Price; (1.75)
NE = Number of erasers; (What we are looking for)
EP = Erasers Price; (0.25);
Then:
4.25 = 1*1.75 + NE*0.25;
4.25 - 1.75 = NE*0.25;
2.5/0.25 = NE;
10 = NE.

grace and her dad are planning to attend the state fair. an adult ticket is $15. the price of an adult ticket is the price of a student ticket plus $8. write an equation to determine how much grace will pay for a student ticket. x 8
Grace will pay $7 for a student ticket.
Let's write the cost of a student ticket as "S." The price of an adult ticket, according to the information provided, is equal to the cost of a student ticket plus $8. Therefore, this relationship can be expressed as an equation:
Price of adult ticket = Price of student ticket + $8
Since the price of an adult ticket is $15 and the price of a student ticket is "S," the equation becomes:
$15 = S + $8
We now need to separate "S" on one side of the equation in order to figure out how much Grace will pay for a student ticket ("S"). To accomplish this, take $8 away from either side of the equation as follows:
$15 - $8 = S
$7 = S

Answer:
y = (x -1)² -16
Step-by-step explanation:
Note the location of the vertex (point A) on the graph. Its x-coordinate is readily identifiable as 1. Its y-coordinate is some value between -15 and -20, closer to -15. (If you go to the trouble of finding the vertex coordinates, you discover they are (1, -16).)
Once you have determined what the vertex is, you can compare the offered answer choices to the vertex form ...
y = (x -h)² +k
where (h, k) are the vertex coordinates. That is, you are looking for an answer choice that is something like ...
y = (x -1)² -16
Mr. Rozario bought some oranges and some apples. The ratio of oranges to apples is 2:5. He gave 3/4 to his sister and 34 oranges to his brother. He now has a ratio of 2:3. How many oranges and apples did he buy?
Answer:
He bought 544 oranges and 1,360 apples
Step-by-step explanation:
Here, we want to know the number of oranges and apples bought
Let the number of oranges be x and the number of apples be y
Looking at their ratios;
x:y = 2:5
so;
x/y = 2/5
2y = 5x ••••••(i)
Now, he lost 3/4 of the apples ( by giving out)
What would be left with him is (1-3/4) = 1/4 * y = 0.25y
What is left with him out if the oranges will be; x-34
So now;
0.25y/x-34 = 2/3
3(0.25y) = 2(x-34) •••••••(ii)
From i, y = 5x/2 = 2.5x
Putting this into ii above, we have
3(0.25)(2.5x) = 2x - 68
1.875x = 2x-68
2x-1.875x = 68
0.125x = 68
x = 68/0.125
x = 544
But y = 2.5x
y = 2.5 * 544 = 1,360

The value is not in the form of p/q so the simplified fraction will be =
-4 and -6.
For the second:
-24 x (-7/6)
On solving this number we get = -24 x (-7/6)
= -4 x -7
= -28
The implies that the number is not a whole number.
The value is not in the form of p/q so the simplified fraction will be = -28/1
For the third:
4 ÷ -6
The can also be written as:
4/-6
on dividing by 2 both numerator and denominator So it gives:
-(2/3)
The implies that the number is not a whole number.
The value is not in the form of p/q so the simplified fraction will be = -(2/3).
For the fourth:
(4/3) ÷ -24
The can also be written as:
(4/3) / -24
On solving this number we get = (4/3) / -24
= 4/72
= -(1/18)
The implies that the number is not a whole number.
The value is not in the form of p/q so the simplified fraction will be =

Valerie gives her dog 12 ounces of food in the morning and 12 ounces of food at night there are 75 ounces of dog food in a bag after how many feedings will she need to buy a new bag of dog food explain how you know Valerie will need to buy a new bag of dog food after blank feedings
Answer:
Valerie will need to buy a new bag of dog food after 6 feedings because she would have 0.25 of feedings left.
Step-by-step explanation:
Total number of ounces of dog food = 75 ounces
Ounces that is fed to the dog is = 12 Ounces in the morning and 12 ounces at night.
Hence:
12 ounces = 1 feeding
75 ounces = x
Cross Multiply
12x = 75
x = 75/12
x = 6.25 feedings
Valerie will need to buy a new bag of dog food after 6 feedings because she would have 0.25 of feedings left.

preimage: J(-3, 0), K(-2, 4), L(-1, 0)

We need to know about translation along vector to solve the probelm. The coordinates of the figure after translation along the vector (5,-4) are (2,-4), (3,0) and (4,-4).
Translation means moving an object from one place to another. Every point on the object moves the same amount of distance and in the same direction. Translation of a point along a vector means moving the point to a different location with respect to the given vector. Here we have three points which form a triangle JKL, we have to translate triangle JKL with respect to the vector (5,-4) to get triangle QRS. Inorder to translate a point along a vector we add the x-coordinate of the vector to the x-coordinate of the point and same for the y-coordinates.
J (-3,0) Q (-3+5,0-4)≡(2,-4)
K (-2,4) R (-2+5,4-4)≡(3,0)
L (-1,0) S (-1+5,0-4)≡(4,-4)
Therefore we get the coordinates of triangle QRS after translation of triangle JKL along vector (5,-4) to be (2,-4), (3,0) and (4,-4)
