Hey there! :)
2x - 3y - z ; When x = -2, y = 3, & z = -2
Since we're given the values of x, y, & z, we can very simply plug everything in!
2(-2) - 3(3) - (-2)
Simplify.
(-4) + (-9) + 2
Get rid of parenthesis.
-4 - 9 + 2
Remember to do PEMDAS!
Parenthesis

So, since adding comes before subtracting, let's add! :)
-4 - 9 + 2
-4 - 7
Simplify.
-11
So, our answer is [A] : -11
~Hope I helped!~

Answer:
A
Step-by-step explanation:
7x/2 = 3
7x = 6
x = 6/7
First, we know that all supplementary angles add to 180°. Then, since the angles are in the ratio 4:5, we can also represent these angles as 4x and 5x respectively. Both angle measures have the same variable (x) because no matter how large the angles are, they must have a common multiple because they are in a ratio. We can then write the formula 4x+5x=180 and solve for x. First, you combine like terms to get 9x=180. The you divide both sides by 9 to get x=20. Then, we can find both angles to be 80 (4*20) and 100 (5*20) by plugging them into 4x and 5x. Since 100 is larger, that is your answer.
I hope this helps.
