Answer:
x=20
Step-by-step explanation:
7x+2x=180(being straight angle )
9x=180
x=180/9
x=20
Answer:

Step-by-step explanation:

Answer:
1) 4 wild cards
2) 51.5 bones, rounded up to 52 bones
3) 72 blue balls.
Step-by-step explanation:
1) For every 18 cards in the game, there is 1 wild card.
For 72 cards in the game, there are 72/18 * 1 = 4 wild cards.
2) For every 4 bones, 1 is in the feet.
For 206 bones, 206/4 * 1 = 51.5 are in the feet. Though, you can't have half a bone, so I'd round it up to 52 bones in the feet.
3) For every 6 + 5 = 11 balls, there are 6 blue and 5 red.
For every 132 balls, there are 132/11 * 6 = 72 blue and 132/11 * 5 = 60 red.
There are 72 blue balls.
1/6th because he used half of a whole part. You just multiply the fraction by 2 and count how many parts are flowers in the whole garden afterward :)
Drawing it out helps too! Good luck!
4×+7y=-12 __ -4x-y=-12 ________ 0x+6y=-24 , so you eleminated by it self 6y/6=-24/6 , you get : y=-4 and then you plug in 4x+7(-4)=-12 , that's your answer 4x-28 =-12 , you divided in both side 4x=-12+28 , 4x=16 , and then x=16/4 =4 , so x=4
