Answer:

x = 6, y = 45

Step-by-step explanation:

$scale \: factor = \frac{13}{32.5} \\ = \frac{2}{5} \\ \\ \frac{x}{15} = \frac{18}{y} = \frac{2}{5} \\ \\ \implies \frac{x}{15} = \frac{2}{5} \\ \\ x = \frac{2 \times 15}{5} \\ \\ x = 6 \\ \\ \frac{18}{y} = \frac{2}{5} \\ \\ y = \frac{5 \times 18}{2} \\ \\ y = 45$

Rearrange like terms in this polynomial so like terms are next to each other

mixer [17]

Answer:

4x^2 - 6x^2 -6x + 3x +3 - 4

Step-by-step explanation:

The terms here involve x^0, x, x^2.

Write the x^2 terms first: 4x^2 - 6x^2;

then write the x terms: -6x + 3x; and

then write the constants: 3 - 4

and so we have, in descending powers of x,

4x^2 - 6x^2 -6x + 3x +3 - 4

Which of these equations, when solved, gives a different value of x than the other three? 9.1 = -0.2x + 10 10 = 9.1 + 0.2x 10 –

garik1379 [7]

Given:

Different equations are given.

Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining.

To find:

The equation which gives a different value of x than the other three.

To find the equations that could you use to find the price of one tire patch.

Solution:

In option A,

$9.1 = -0.2x + 10$

$0.2x= 10-9.1$

$0.2x= 0.9$

Divide both sides by 0.2.

$x=\dfrac{0.9}{0.2}$

$x=4.5$

Similarly,

In option B,

$10 = 9.1 + 0.2x$

$0.9= 0.2x$

$4.5=x$

In option C,

$10-0.2x = 9.1$

$-0.2x = -0.9$

$x = 4.5$

In option D,

$9.1 – 10 = 0.2x$

$-0.9 = 0.2x$

$-4.5 = x$

Since option D has difference solution, therefore the correct option is D.

Let price of one tire patch be x.

So, price of 4 tire patches = 4x

Remaining amount in Rhyan's gift card = $1.90

Total amount = $22.20

Price of 4 tire patches + Remaining amount in gift card = Total amount

$4x+1.9=22.2$

It can be written as

$4x-22.2=-1.9,1.9=22.2-4x,22.2-4x=1.9$

Therefore, the correct options are C and E.

Find the area of an equilateral triangle if a side is 8*sqrt(3) m. Round to the nearest whole number.

gavmur [86]

Hello,

8*√3 is the side.
The height is √((8√3)²-(4√3)²)=√(64*3-16*3)=12

Area of the triangle=8*√3*12/2=48√3≈83

WILL GIVE BRAINLIEST

leonid [27]

Set up a system of equations and say green route is x and blue route is y

This will give you
Monday 6x + 5y= 52
Tuesday 12x + 13y = 119

Solve by multiplying the top equation by two to get
12x + 10y= 104

Since you have 12x in both equations, these cancel out when you subtract the bottom from the top. This leaves you with

-3y=-15
Y=5

The blue route is 5 miles, but they want to know the green route. Fill in the y value in either one of your equations. Let’s use the one from Tuesday

12x + 13 (5) = 119
12x= 54
X= 4.5

This means that the answer is B, 4.5 miles
