Answer:
78 ants are red
Step-by-step explanation:
To solve this find out that percentage of the ants that are red. To do this divide 10 by 24. This gives you 0.42 when rounded to the nearest hundredth. 0.42 is also 42%. Take the total 186 ants and multiply it by 0.42. This gives you 78.12. Since you can't have part an ant round it down to 78.
Each one is multiplied by -2...
PROOF
-5 * 10 = -20
-20 * -2 = 40
And so on.
So we need two more numbers so do 40 * -2...
40 * -2 = -80
And then...
-80 * -2 = 160
So the first 6 numbers are...
-5, 10, -20, 40, -80, 160.
We need to find the SUM, which is all the numbers added together.
-5 + 10 - 20 + 40 - 80 + 160 = 105
105 is your answer.

7x = 21*4
7x = 84
x = 84/7
