Answer:
x=61 -> Figure A
x=27 -> Figure B
x=12 -> Figure C
Step-by-step explanation:
<u>For A:</u>
<u>x=61</u> because the line going through the shape cuts in angle into 2 congruent angles
<u>For B:</u>
The corner adds up to 90 because it a rectangle, and rectangles only have right angles.
So: 2x+10+x-1=90
Solve.
3x+9=90
3x=81
<u>x=27</u>
<u>For C:</u>
The two given angles should add up to 90.
4x+10+2x+8=90
Solve.
6x+18=90
6x=72
<u>x=12</u>
Answer:
4/52 or 1/13
Step-by-step explanation:
In a standard deck of 52 cards, there are 4 suits and each suit has 13 cards.
There are 4 kings, 4 queens, 4 aces, and 4 jacks.
So the probability of drawing a king would be:
4/52 = 1/13
31. It gives you the equation f(x) = -2x + 4 and asks you to solve for f(12). To solve this you must replace x in the equation -2x + 4 with 12 like so:
-2(12) + 4
Remember that when solving this use your rules of PEMDAS. In this case you will first multiply -2 and 12 then add the product with 4
-24 + 4
f(12) = -20
33. Replace x in the equation x³ - x with 5 like so...
5³ - 5
Again, remember to use the rules of PEMDAS to solve this. First take the cube of 5 then subtract 5 from the answer
125 - 5
g(5) = 120
