Just replace all of the x’s with 5 and solve using order of operations. I will post what I got for my answer in the comments of the answer if you need it.

Instructions: Find the lengths of the other two sides of the isosceles right triangle below.

Alexandra [31]

Given:

The ratio of 45-45-90 triangle is $x:x:x\sqrt{2}$ .

The hypotenuse of the given isosceles right triangle is $7\sqrt{2}$ .

To find:

The lengths of the other two sides of the given isosceles right triangle.

Solution:

Let $l$ be the lengths of the other two sides of the given isosceles right triangle.

From the given information if is clear that he ratio of equal side and hypotenuse is $x:x\sqrt{2}$ . So,

$\dfrac{x}{x\sqrt{2}}=\dfrac{l}{7\sqrt{2}}$

$\dfrac{1}{\sqrt{2}}=\dfrac{l}{7\sqrt{2}}$

$\dfrac{7\sqrt{2}}{\sqrt{2}}=l$

$7=l$

Therefore, the lengths of the other two sides of the given isosceles right triangle are 7 units.

The quotient of two numbers is 4, and the difference is 3. What are the two numbers

Pie

Answer:

The numbers are 4 and 1

Step-by-step explanation:

Let x and y be the numbers

Quotient is division

x/y = 4

x-y =3

Taking the first equation and multiplying each side by y

x = 4y

Replacing into the second equation

4y -y = 3

3y = 3

Divide by 3

3y/3 = 3/3

y=1

Now we can find x

x -y =3

x-1 =3

Add 1 to each side

x= 4

forsale [732]

Answer:

$Quadrant\ IV = (5, -3)$

$Quadrant\ I = (9, 11)$

$Quadrant\ II = (-1, 3)$

$Quadrant\ III = (-2, -4)$

Step-by-step explanation:

Given

$Quadrant\ IV = (5, -3)$

$Quadrant\ II = (-4, -8)$

$Quadrant\ I = (9, 11)$

$Quadrant\ II = (-1, 3)$

$Quadrant\ III = (-2, -4)$

Required

Determine which coordinate fall in the right quadrant

First, we split the each quadrant into x and y axis

In the first:

x and y is +

In the second:

x is - and y is +

In the third

x and y are -

In the fourth

x is + and y is -

Comparing the given coordinates to their respective quadrants, base on the conditions stated above

$Quadrant\ IV = (5, -3)$ is correct

$Quadrant\ I = (9, 11)$ is correct

$Quadrant\ II = (-1, 3)$ is correct

$Quadrant\ III = (-2, -4)$ is correct

$Quadrant\ II = (-4, -8)$ is incorrect
