Answer:

2x - (3 + 4x) = 12

x = -7.5

y = -27

Step-by-step explanation:

-4x + y = 3 (1)

2x - y = 12 (2)

From (1)

y = 3 + 4x

Substitute y = 3 + 4x into (2)

2x - y = 12 (2)

2x - (3 + 4x) = 12

2x - 3 - 4x = 12

2x - 4x = 12 + 3

-2x = 15

x = 15/-2

x = -7.5

Substitute x = -7.5 into (2)

2x - y = 12 (2)

2(-7.5) - y = 12

-15 - y = 12

-y = 12 + 15

- y = 27

y = -27

Answer:[tex]\frac{17}{35}[/tex]

Step-by-step explanation:

Given

The bag contains 6 orange and 9 lime sweets

For both sweets of the same flavor, Jodi must either choose orange or lime

No. of ways it can be done is [tex]^6C_1\times^5C_1+^9C_1\times^8C_1[/tex]

The total no of ways of selecting two sweets out of 15 is [tex]^{15}C_1\times^{14}C_1[/tex]

The probability that both sweets are the same flavor

[tex]P=\dfrac{^6C_1\times^5C_1+^9C_1\times^8C_1}{^{15}C_1\times^{14}C_1}=\frac{102}{210}=\frac{51}{105}=\frac{17}{35}[/tex]

Answer:

y = 2

Step-by-step explanation:

Given

[tex]\frac{2y-1}{15}[/tex] = [tex]\frac{y}{10}[/tex] ( cross- multiply )

10(2y - 1) = 15y ← distribute left side

20y - 10 = 15y ( subtract 15y from both sides )

5y - 10 = 0 ( add 10 to both sides )

5y = 10 ( divide both sides by 5 )

y = 2

Answer:

2

Step-by-step explanation:

27 = 54,

let's say the value that will make it true is x

So then,

27 * x = 54. If we divide both sides by 27, we have

x = 54 / 27

x = 2

The value that will make it true is multiplying 27 by 2

Answer:

the answer would be 25

Step-by-step explanation:

since if you add all the following numbers up you make 11 and to taht you double the answer and that would give you 22 and then you add the remaining IP to make 25b

56.25

Step-by-step explanation:

6*9=54+2.25= 56.25

Answer:

$56.25

Step-by-step explanation:

So first off we have 6 1/4 hours being worked at the rate of 9 dollars and hour. 6 hours multiplied by 9 dollars will give you 54 dollars. After that all we need to do is get a quarter of 9 dollars, which is $2.25 adding this to our original number of 54, we have $56.25. Hope this helps!

Mia is able to find the height of the students so accurately using the tangent property of trigonometry.

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The base is the adjacent smaller side of the angle θ.

As it can be seen that there are two right triangles, therefore, using the tangent property of the trigonometry, Mia is able to find the height of the students so accurately.

Answer:

x=1 and y= -4

Step-by-step explanation:

step one: plug -4x into y in thi]e first equation.

2x+5(-4)= -18

step two: solve for x

2x-20= -18

(add 20 to both sides to eliminate -20 on the right)

2x=2

(divide both sides by 2 to get x by its self)

x=1

step 3: now that we found the value for x plug it in to either equation and solve for y

y= -4x

y= -4(1)

y= -4

Answer:

129

Step-by-step explanation:

the answer is 129 because you do 0.50 times 86 which is 43 so you do 43 + 86 which is 129 so $129 is your answer

The selling price of an $86 item after a 50% markup will be $129.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

The price of an item is $86 and the price is increased by 50%.

Let 'x' be the selling price. Then the selling price is calculated as,

50% = [(x - 86) / 86] x 100

Simplify the equation, then we have

50% = [(x - $86) / $86] x 100

0.50 = (x - $86) / $86

$43 = x - $86

x = $86 + $43

x = $129

The selling cost of a $86 thing after a half markup will be $129.

Answer:

Step-by-step explanation:

area of square is basically one side times itself

14 times 14 =196m^2

Answer: 196 meters

Step-by-step explanation: To find the area of any square you must do length(vertical side) times the width(horizontal side). It would look like this: length x width. So in this equation, it would be 14x14=the area. Another thing is that when you have a square when you know one side the other side is always as long or wide as the one you know. So 14x14=196 square meters
