Find the length of the missing side. If necessary, round to the nearest tenth.

1 answer:

4 0

The correct answer would be A. 21.5
a^2 + b^2 = c^2

so....
100 + 361 = c^2
The square root of 461 is 21.4709106 but you would round to 21.5

In the given system of equations, the value of x is 7.334 and the value of y is 7.714

<h3>Solving system of linear equations</h3>

From the question, we are to solve the given system of linear equations

The given system of linear equations is

3x + 7y = 76 ------------ (1)

9y + 5y = 108 ------------ (2)

From equation (2), solve for y

9y+ 5y = 108

14y = 108

y = 108/14

y = 7.714

Substitute the value of x into equation (1), to determine the value of x

3x + 7y = 76

3x + 7(7.714) = 76

3x + 53.998 = 76

Subtract 53.998 from both sides of the equation

3x + 53.998 - 53.998 = 76 - 53.998

3x = 22.002

Divide both sides of the equation by 3

3x/3 = 22.002/3

x = 7.334

Therefore,

x = 7.334 and y = 7.714

boyakko [2]

X => -8 -6 -8 3
y => 33 31 39 33
is not a function because the x value -8 results to two different y-values 33 and 39.

What is the correct first step to solve this system of equations by elimination?

storchak [24]

$\bold{\huge{\pink{\underline{ Solution }}}}$

$\bold{\underline{ Given }}$

We have given two linear equations that is 2x - 3y = -6 and x + 3y = 12 .

$\bold{\underline{ To \: Find }}$

We have to find the value of x and y by elimination method.

$\bold{\underline{ Let's \: Begin }}$

$\sf{ 2x - 3y = -6 ...eq(1)}$

$\sf{ x + 3y = 12 ...eq(2)}$

Multiply eq( 2 ) by 2 :-

$\sf{ 2( x + 3y = 12 )}$

$\sf{ 2x + 6y = 24 }$

Subtract eq(1) from eq(2) :-

$\sf{ 2x + 6y -( 2x - 3y) = 24 -(-6)}$

$\sf{ 2x + 6y - 2x + 3y = 24 + 6 }$

$\sf{ 9y = 30 }$

$\sf{ y = 30/9}$

$\sf{\red{ y = 10/3}}$

Now, Subsitute the value of y in eq( 1 ):-

$\sf{ 2x - 3(10/3) = -6 }$

$\sf{ 2x - 10 = -6 }$

$\sf{ 2x = -6 + 10}$

$\sf{ x = 4/2}$

$\sf{\red{ x = 2}}$

Hence, The value of x and y is 2 and 10/3
