Let r, g and b represent red, green and blue.
r+g+b = 74
r=g-1
b=r+g
Again, r+g+b = 74. Let's substitutte r+g for b: r+g+(r+g) = 74.
Next, let's eliminate r. Use r=g-1. Then g-1 + g + g-1 + g = 74
Combining the g terms, 4g - 2 = 74 => 4g = 76 => g = 19
Recall that r=g-1
and
b=r+g
Find r. If r=g-1, and g=19, then r = 19-1=18
Find b: b = r+g = 18+19=37
So there are 37 blue candies, 18 red candies and 19 green candies.
Check: 37+18+19=74 ??? Yes.
Answer:
11
Step-by-step explanation:
If we input 11 into the equation, we get: 10 + 5(11) = 65.
5 x 11 = 55
55 + 10 = 65
Therefore x = 11
If you would like to know whether or not what she wrote is accurate, it is.
Hope that helps!
Isolate c by subtracting all sides by 4
Then divide all sides by -5
You should get
5 less than or equal to c less than or equal to 4
Hope this helped :)
