Answer:

x is equal to 27

Step-by-step explanation:

To find this, start by making a proportion. In order to do so, you need to set it up using the smaller triangle on the right and the larger triangle on the left.

39/x = 65/(x + 18)

Now cross multiply to solve.

65*x = 39(x + 18)

65x = 39x + 702

26x = 702

x = 27

Round 10,386.145 to the nearest tenth

Svetradugi [14.3K]

Rounded to the nearest tenth would be one since the four isn't higher. So the answer would be 10,386.1. You did mean the tenths place right?? because could have also meant tenth(8)

The correct answer is a. In the left-hand column, each number goes up by one. In the right hand column, each number goes up by 1120. Each number on the left can be multiplied by 1120 to get the number on the right.

X + y = -1<br> 4x - 2y = -16

djyliett [7]

Answer:

$x=-3 \\and\\ y=2$

Step-by-step explanation:

$x + y = -1$ Equation:1

$4x - 2y = -16$ Equation:2

Solving Equation:1

$x+y=-1$

Subtracting 'y' from both the sides:

$x+y-y=-1-y\\\\x=-1-y$

Putting 'x' in Equation :2

$4(-1-y)-2y=-16\\\\-4-4y-2y=-16\\\\-4-6y=-16$

Adding '4' both the sides

$-6y=-16+4\\\\-6y=-12\\\\y=-12/-6\\\\y=2$

Putting the value of 'y' in equation:1

$x+y=-1$

$x+(2)=-1\\\\x=-1-2\\\\x=-3\\$

The solution is:

$x=-3 \\and\\ y=2$

80 points! Look at pic attached. I will mark brainiest if you explain your reasoning good. Random answers will be reported.

gregori [183]

Answer: No, your friend is not correct. You cannot use a similarity transformation to turn a square into a rectangle. Here's why:

1) If you used a similarity transformation, the size and position of the shape would change, but the shape itself remains the same.

2) Squares and rectangles are NOT similar.* Referring to the first point I listed, if the shapes are not similar, then a similarity transformation cannot be used to turn one shape into another.

<em>*Similar means that the edges are proportional to one another, such as a square with sides of 4 meters vs a square with sides of 2 meters: the sides are different lengths, but the shape is the same.</em>

I hope this helps! Please feel free to comment below if you need any clarification. Have a good day, and good luck on your assignment. :)
