Answer:

x = 19

Step-by-step explanation:

These are vertical angles, which means that the angle measurements are going to be the same. Set the two angle measurements equal to each other:

3x - 3 = 6(x - 10)

Simplify. First, distribute 6 to all terms within the parenthesis:

3x - 3 = 6(x - 10)

3x - 3 = 6(x) - 6(10)

3x - 3 = 6x - 60

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 3 and subtract 6x from both sides:

3x (-6x) - 3 (+3) = 6x (-6x) - 60 (+3)

3x - 6x = -60 + 3

-3x = -57

Isolate the variable, x. Divide -3 from both sides:

(-3x)/-3 = (-57)/-3

x = -57/-3 = 57/3 = 19

x = 19 is your answer.

Answer:

not

Step-by-step explanation:

$\left[\begin{array}{ccc}-2&4\\1&3\end{array}\right] *\left[\begin{array}{ccc}-2&1\\3&7\end{array}\right]=$

First is A and Second is B

Let's find A*B

$\left[\begin{array}{ccc}-2(-2)+4*3&-2*1+4*7\\1(-2)+3*3&1*1+3*7\end{array}\right] =\left[\begin{array}{ccc}16&26\\7&22\end{array}\right]$

$\left[\begin{array}{ccc}-2&1\\3&7\end{array}\right] \left[\begin{array}{ccc}-2&4\\1&3\end{array}\right] =$

Now let's find B*A

$\left[\begin{array}{ccc}-2(-2)+1*1&-2*4+1*3\\3(-2)+7*1&3*4+7*3\end{array}\right] =\left[\begin{array}{ccc}5&-5\\1&23\end{array}\right]$

-3x -4y = 20 x - 10y =16 if (x, y) is the solution to the system of equations above what is the value of x?

balu736 [363]

Multiply first equation by -5 and 2nd by 2, add them

15x+20y=-100
<u>2x-20y=32 +</u>
17x+0y=-68

17x=-68
divide both sides by 17
x=-4

the x value is -4
