Answer: lil is 13 jack is 39
Step-by-step explanation: 52 divided by 4 is 13 (lil) and 13 times 3 is 39 (jack) so, 13 plus 39 equals 52
It would be 30 because when you add 5z to a -5z those cancel out so what you have left would be 20+10 and you would add those together and get 30.
4x = y - 1 ⇒ 4x + y = -1 ⇒ 12x + 3y = -3
6x - 2y = -3 ⇒ 6x - 2y = -3 ⇒ <u>12x - 4y = -6</u>
<u>7y</u> = <u>3</u>
7 7
y = 3/7
12x + 3(3/7) = -3
12x + 1 3/7 = -3
<u> -1 2/7 -1 2/7</u>
<u>12x</u> = <u>-4 2/7</u>
12 12
x = -5/14
(x, y) = (-5/14, 3/7)
Does this means like 1.5 meter is equal to 30cm in for example in an miniature build?
if in real life you measure 1.5 meter in total, you can transfer this into a miniture build which makes it 30cm in your build. If you measure the length of a car by 3m, and you want to make a miniature build of it, you can do 30cm x 2 ( because 3m is 2x 1.5 ) and in a miniature build you have to make you build 60cm in length
I hope this makes it clear for you.
