X = Bigger number is 5/3
y = Smaller number is 1/3

Solution
x = 5y
x + y = 3 - 3y which is x + 4y = 3

So, then replacing x with 5y in the second equation we get
5y + 4y = 3
So y = 1/3
Then coming back to the first equation
x = 5/3

Check the result with the second equation
5/3 + 1/3 = 3 - 3/3

Find the missing lengths of the sides.
Anarel [89]

Given:

The figure of a right angle triangle.

a=b

Hypotenuse = 9\sqrt{2} in.

To find:

The missing lengths of the sides.

Solution:

In the given right angle triangle both legs a and b are equal, and hypotenuse is 9\sqrt{2} in.

Using Pythagoras theorem, we get

Hyponteuse^2=Base^2+Perpendicular^2

(9\sqrt{2})^2=(a)^2+(b)^2

81(2)=(a)^2+(a)^2                    [\because a=b]

81(2)=2(a)^2

Divide both sides by 2.

81=(a)^2

Taking square root on both sides.

\pm \sqrt{81}=a

\pm 9=a

Side cannot be negative. So,

9=a

Thus, the missing side lengths are a=9 in and b=9 in.

Therefore, the correct option is C.

13 please I have no idea what the steps for this is
Ilya [14]

Answer:

UV=142

Step-by-step explanation:

21x-13=10x+31

+13 +13

21x=10x+44

-10x=-10x

11x=44

÷11 ÷11

x=4

now substitute 4 in place of x (only have to solve one)

21(4)-13= 71

now multiply your answer by 2

71×2=142
