Sure but wheres the picture?
I'm not sure what side is missing but you could use the proportions
A/B=X/Y or B/C=Y/Z or CA/=ZX. it also works if you reverse this for example B/A=Y/X
B)7:8 is the answer because:
16 total - 7 green = 8 and so
the ratio of GREEN to RED is
7:8
7 green 8 red
For a) it would be 1:2 as it is 16:8 and simplified would make it 1:2
Heyy there, i couldnt find the line
Answer:
(143/74, -65/148)
Step-by-step explanation:
We have the equations:
4x - 12y = 13
14x + 32y = 13
Let's use elimination, so multiply the first equation by 8 and the second equation by 3:
8 * (4x - 12y = 13) ⇒ 32x - 96y = 104
3 * (14x + 32y = 13) ⇒ 42x + 96y = 39
Add those two equations:
32x - 96y = 104
+ 42x + 96y = 39
________________
74x + 0y = 143
Divide both sides by 74:
x = 143/74
Plug this into an equation to find y:
4x - 12y = 13
4 * (143/74) - 12y = 13
12y = 572/74 - 13 = -390/74
y = -65/148
The answer is (143/74, -65/148).
