Answer:
20:64
Step-by-step explanation:
total = 92
red = 8
blue = 20
green = x
20:X
------------
92 - 28 (blue + red) will give you the amount of green, which is 64
so the blue:green ratio is 20:64
Answer:
No
Step-by-step explanation:
substitute -2 for 'x' and 5 for 'y'
2(-2) + 5(5) = 0?
-4 + 25 = 21, not 0
Answer
You can multiply the first equation by 4 and the second equation by 3.
You can multiply the first equation by 4/3.
You can multiply the first equation by 3.
Explanation
When solving a system of equations by elimination, you want to add or subtract the equations to "get rid" of a variable.
To do that, one of the variables in both equations have to have the same coefficient.
The first answer possible gives x the coefficient of 12 for both equations. You would get 12x+4y=52 and 12x-9y=39. You could subtract those equations to get 13y=13.
The second way gives x the coefficient of 4. You would multiply the first equation by 4/3 to get 4x+4/3y=52/3. You can subtract to get one variable, and then solve from there. Although, multiplying for 4/3 is annoying, so it's not suggested.
You can also "get rid" the the y. Multiply the first equation by 3 to get 9x+3y=39. You can add these equations. When you add 9x+3y=39 and 4x-3y=13 you get 13x=52.
Answer:
-22
Step-by-step explanation:
Each line is worth 3 units
-10 - (-16) = 6 units between and there are 2 spaces
6/2 = 3
We are going down so it is negative
-16 -3 =-19
then the dot is on the next line
-19 -3 = -22
