Identify the solution of the system -2x-4y=1 12y=-6x-3

1 answer:

6 0

-2x - 4y = 1
12y = -6x - 3
12 12
 y = -0.5x - 0.25

-2x - 4(-0.5x - 0.25) = 1
-2x + 2x + 1 = 1
0x + 1 = 1
 - 1 - 1
 0x = 0
 0 0
 x = 0
-2(0) - 4y = 1
0 - 4y = 1
-4y = 1
-4 -4
 y = -0.25
(x, y) = (0,-0.25)

Lisa has 12 more stickers than John, and together they have 60 stickers. What is the ratio of the number of Lisa’s stickers to t

Andru [333]

You can work this several ways. One way is to figure out how many stickers each has, then write their relationship as a ratio.

Here, Lisa will have 12/2 = 6 more than half the total number of stickers, hence 36. John will have the remaining 24. Their ratio is
Lisa's stickers : John's stickers = 36 : 24 = 3 : 2

Another way to look at this is to realize 12 divides 60 into 5 equal parts. The ratio that will total 5 parts with one number being 1 larger than the other is 3 : 2.
Lisa's stickers : John's stickers = 3 : 2
