Answer:

Variable x in first equation

Step-by-step explanation:

Given system

x = 5y - 1x + 2y = 13

Variables in this system are x and y.

Isolating a variable means rearranging the equation so that a variable of our interest is on its own in one side of the equal sign.

We see variable x is isolated in the first equation.

In the second equation both of the variables are on the same side so they are not isolated.

Answer:

x

Step-by-step explanation:

x=5y-1--(1)

The x variable is isolated here as it's solo on left side

Solve the equations

x+2y=13x=-2y+13--(2)

Equate

5y-1=-2y+137y=14y=2

x=10-1=9

Answer:

Step-by-step explanation:

So there we have it, <A=135° and <B=45°. This should check when you add them together ("<A and <B are supplementary which means that together their angles equal 180°"). Does 135°+45=180°?     YES!

O A. 85°
O B. 105°
O c. 75°
D. 95°

Answers

Answer:

A. 85°

Step-by-step explanation:

By interior angle sum theorem of a triangle.

x = 180° - ( 40° + 55°)

x = 180° - 95°

x = 85°

Answer:

A. 85

Step-by-step explanation:

Youd do 40+55 and that equals 95 and then since a triangle qdds up to 180 degrees, 180-95=85

The expansion of the given logarithm [tex]\mathbf{Log_3 (4x^2)}[/tex] is [tex]\mathbf{= 2log_3(2)+2log_3(x)}[/tex]

What is the expansion of the logarithm?

A Logarithm is an exponent to which a base must be raised in order to result in a given number. The expansion of the logarithm takes a predictable approach and set guidelines.  

Using the set formula for solving logarithms;

[tex]\mathbf{log_a(x^n) = n \ log_a \ x}[/tex]

Let's assume that the correct equation given is:
[tex]\mathbf{=Log_3 (4x^2)}[/tex]

Using the above formula, we have

[tex]\mathbf{= 2 Log_3 (4x)}[/tex]

By expansion;

[tex]\mathbf{= 2log_3(2)+2log_3(x)}[/tex]

Looking at the letter arrangement in the problem B is similar to W

Set those equal to each other and solve.

X + 24 = 2x -2

Subtract x from both sides:

24 = x -2

Add 2 to both sides:

X = 26

Now replace x in the equation for B

2x -2 = 2(26)-2 = 52-2 = 50

B = 50 degrees

Solve the equation 18+a= -50

Answers

18+a=-50
a+18=-50
Subtract 18 from both sides
a=-68

Answer:

-68

Step-by-step explanation:

Subtract 18 from each side of the equation.

a + 18 = -50

    -18    -18

Turn -50 - 18 into -50 + (-18) because you need to add the opposite.

a = -50 + (-18)

a = 68

The angle opposite to a greater side is less than 90° and the sum of the squares are close.

It means all three angles are less than 90°.

With this the triangle is acute.
