Answer:

5x+1

Step-by-step explanation:

the perimeter is the outside values of the shape, and we know all the values, so we just have to add them all up.

(x+4) + (2x-1) + (3x-2) = perimeter

since it's all subtraction and addition we can remove the parentheses

x+4+2x-1+3x-2 = perimeter

now let's put all the x's on one side and the numbers on the other side to make it easier

x+2x+3x+4-1-2= perimeter

5x+1

Answer:

Perimeter of the triangle is :---

$(x + 4) + (3x - 2) + (2x + 1) \\ = x + 4 + 3x - 2 + 2x + 1 \\ = \boxed{(6x + 3 )\: ft }$

<h3><u>(6x+3) ft</u> is the right answer.</h3>

Answer:

x = $25.8^{o}$ and y = $51.4^{o}$

Step-by-step explanation:

Known that he sum of angles on a straight line is $180^{o}$ . From the diagram;

2y + x + y = $180^{o}$

x + 3y = $180^{o}$ ................ 1

Also,

2x + x + 2y = $180^{o}$

3x + 2y = $180^{o}$ .............. 2

Using the elimination method, multiply equation 1 by 3 and equation 2 by 1

3x + 9y = 540 ............ 3

3x + 2y = $180^{o}$ ............. 4

7y = 360

y = $\frac{360}{7}$

y = $51.4^{o}$

substitute the value of y in equation 1,

x + 3y = $180^{o}$

x + 3(51.4) = $180^{o}$

x + 154.2 = $180^{o}$

x = $180^{o}$ - 154.2

x = $25.8^{o}$

Thus, x = $25.8^{o}$ and y = $51.4^{o}$

What is the answer for 0.2/n = 0.4/0.6

LenaWriter [7]

Answer:

n=0.3

Step-by-step explanation:

divide the numbers

0.2/n=0.4/0.6

0.2/n=.066666

then you multiply by the same dominator to both sides

n*.02/n=n*.066666

Cancel multiplied terms that are in the denominator

0 . 2 =
