Answer:

x=9

Step-by-step explanation:

2(x-3)=12

First you use the distributive property

so you do 2 times x then 2 times -3

rewrite it as 2x-6=12

add 6 on both sides

2x=18

divide 2 from both sides and you get x=9

Please help I don't understand

17) The line that is John is closer to certain but not exactly on certain so I'd say it's "likely"

18) Using that same example as the one above, if 0 means impossible, then 1 means certain. I'd place your label for Sara at 1. 

19) Let s = sides of the square. There are 4 sides and all sides are equal so we can set up the equation 4s = 64. Divide both sides by 4. s =  16. Now add 2 to this. 16 + 2 = 18. The length of each side of the original square was 18.

20) If the scale is 1 cm : 1 meter and the height of the model is 16 cm, then the actual plane must be 16 meters. 

21) 2x and 100 are supplementary angles meaning together they must add up to 180.

2x + 100 = 180
2x = 180 - 100
2x = 80
Divide both sides by 2
x = 40

22) Assuming 3x is supposed to be the right angle, right angles are 90 degrees. 

3x = 90
Divide by 3 on both sides
x = 30.

Mariah makes bead necklaces. Beads are packaged in bags of 50 and bags of 200. Mariah bought 4 bags of 50 beads and 3 bags of 20
nalin [4]
Since she bought 4 bags of 50 beads and 3 bags of 200 beads you only need to use two operations: multiply and add. 4 x 50 is 200 3 x 200 is 600 600 + 200 = 800 Mariah purchase 800 beads in total.
