Answer:
Option C
Step-by-step explanation:
Given the following question:
[tex]2x+4y=18[/tex]
[tex]-3x+2=y[/tex]
To find the answer we need to find the values of each of the variables by solving one equation at a time, and then substitute those answers into each equation in till we have our answers.
[tex]2x+4y=18[/tex]
[tex]-3x+2=y[/tex]
[tex]y-y=0[/tex]
[tex]-3x+2+ -y=0[/tex]
[tex]2-2=0[/tex]
[tex]-3x+-y=0+-2[/tex]
[tex]-3x+3x=0[/tex]
[tex]-y=3x-2[/tex]
[tex]-y\div-1=y[/tex]
[tex]3x+2\div-1=-3x+2[/tex]
[tex]y=-3x+2[/tex]
Substitute y for -3x + 2:
[tex]2x+4y=18[/tex]
[tex]y=-3x+2[/tex]
[tex]2x+4(-3x+2)=18[/tex]
[tex]2x+4(-3x+2)=18=-10x+8=18[/tex]
[tex]-10x+8=18[/tex]
[tex]8-8=0[/tex]
[tex]18-8=10[/tex]
[tex]-10x=10[/tex]
[tex]-10x\div10=x[/tex]
[tex]10\div-10=-1[/tex]
[tex]x=-1[/tex]
Substitute x for -1:
[tex]y=-3x+2[/tex]
[tex]x=-1[/tex]
[tex]y=-3(-1)+2[/tex]
[tex]-3\times-1=3[/tex]
[tex]y=3+2[/tex]
[tex]3+2=5[/tex]
[tex]y=5[/tex]
[tex]x=-1[/tex]
[tex]y=5[/tex]
Your answer is "(-1, 5)" or option C.

The circle below represents one whole
What percent is represented the shaded area
Answer:
50%
Step-by-step explanation:
Imagine a pizza, the pizza is cut into 4 slices and 2 have already been eaten. There you go! You now have the fraction 2/4. 2/4=1/2. 1/2 as a percentage is 50%.
A segment has one endpoint at the origin O and the other endpoint at A(12,36). If point B is located on OA such that OA/BA=3 then which of the following are the coordinates of B?
(1) (4,12) (2) (9,27) (3) (8,24) (4) (36,108)
The distance between (8, 24) and (12, 36) is one-third of the distance between (0, 0) and (12, 36).
How to find the coordinates of point B?We know that:
O = (0, 0)A = (12, 36).And point B is between these two, such that:
OA/BA = 3
Meaning, OA is 3 times BA.
Now, if we apply a factor of 1/3 to point A, we get:
(12/3, 36/3) = (4, 12)
So, the distance between A and B is equal to the distance between the origin and (4, 12) (a change of 4 units in the x-component and 12 units in the y-component).
The point that meets that condition is (8, 24), which is given by multiplying by 2 the previous coordinates.
The distance between (8, 24) and (12, 36) is one-third of the distance between (0, 0) and (12, 36).

Final Question: What is the measure of x?
Angles are not necessarily drawn to scale.
Answer:
[tex]x=114[/tex]
Step-by-step explanation:
Since we know that a straight line is 180°, and we know that one of the angles is 66°, we can write a simple equation to figure this out: [tex]x+66=180[/tex] Then, to solve the equation all you would need to do is subtract [tex]66[/tex] from both sides to get [tex]x=114[/tex].

7x^4y^2 - 12x^3y^3
Factor out x^3
x^3(7xy^2 - 12y^3)
Factor out y^2
x^3y^2(7x - 12y)

Step-by-step explanation:
n the card game The Dragons of Castlenook, players score points based on the cards they have at the end of the game. Before playing, Reagan randomly selects 13 cards from the 80-card deck and gets 5 dragons, 1 cyclops, 4 ogres, and 3 centaurs. Based on the data, estimate how many ogre cards are in the deck.
Using proportions, it is found that the estimate of the number of ogre cards in the deck is of 24.6.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, out of 13 cards, 4 are ogres. How many are ogres out of 80? The rule of three is given by:
13 cards - 4 ogres.
80 cards - x ogres.
Applying cross multiplication:
13x = 320.
x = 320/13
x = 24.6.
The estimate of the number of ogre cards in the deck is of 24.6.

How do you find the length of AC? Picture below
Answer:
12cm
Step-by-step explanation:
this is a right angle triangle
so taking 'b' as base, 'a' as perpendicular and 'c' is hypotenuse which is equal to 13cm
and 1 angle is given which 22.6 degrees
and we need to find out 'b' which is AC
so we have
sin(x)= perpendicular/hypotenuse
cos(x)= base/hypotenuse
tan(x)=perpendicular/base
cos(22.6) = base/hypotenuse=13
cos(22.6)*13 = base
0.9232*13 = base
base = 12cm

Can the sides of a triangle have lengths 7.6, 2.5, and 2.2?
Answer:
No.
Step-by-step explanation:
Given the following question:
[tex]7.6, 2.5, 2.2[/tex]
In order for any given sides to form a triangle it has to pass the triangle inequality theorem, which is the sum of any two given sides of the triangle has to be greater than the third side in order for it to be a triangle.
In this case...
[tex]7.6, 2.5, 2.2[/tex]
[tex]7.6 + 2.5 = 10.1[/tex]
[tex]10.1 > 2.2[/tex]
[tex]2.5+2.2=4.7[/tex]
[tex]4.7 < 7.6[/tex]
[tex]7.6 +2.2=9.8[/tex]
[tex]9.8 > 7.8[/tex]
Therefore, your answer is "no" the following sides do not form a triangle.

A store sells two brands of applesauce.
Which brand provides more servings?
brand A: 24 1/2 ounces 2/3 cup per serving
brand B: 30 2/3 ounces 3/4 cup per serving
Alternative text
A.
Brand A because it provides 4 19/32 servings.
B.
Brand A because it provides 16 1/3 servings.
C.
Brand B because it provides 5 1/9 servings.
D.
Brand B because it provides 23 servings.
This problem is a dog of a bear because of the units.
It tells us how many ounces are in a jar, but how many cups are in a serving.
So in order to figure out how many servings are in a jar, we have to either change the jar from ounces to cups, or else change the serving from cups to ounces.
And of course, in order to do either of those things, we need to know how many ounces make 1 cup ! Hint: 1 cup = 8 ounces .
AND PLUS trying to work with all the fractions is gonna be ridiculous too.
Jar-A: (24 1/2 ounces) / (8 ounces/cup) = 3 1/16 cups
How many servings is that ?
(3 1/16 cups) / (2/3 cup/serving) = 4 19/32 servings
Jar-B: (30 2/3 ounces) / (8 ounces/cup) = 3 5/6 cups
How many servings is that ?
(3 5/6 cups) / (3/4 cup/serving) = 5 1/9 servings
(5 1/9) is more than (4 19/32). So Jar-B provides more servings than Jar-A.
Choice - C
Note: Both brands are great for people who are on a diet, because they have to work off so many calories working out the stupid fractions, and it takes so long that they never get around to eating the applesauce.
Answer:
ar-B provides more servings than Jar-A. Choice - C
