To keep the balance, add 5 to each side. Example 2. Solve the equation -8 = n - (-4). Solution: After simplifying the right side of theequation, use the subtraction property of equality to subtract 4 from both sides of theequation

Ok, so for example, we have an equation of 4x+5 = 17. To solve for x, we first subtract 5 on both sides. This is called Subtraction Property of Equality.

A drink contains 20% cranberry juice and the rest is apple juice. What is the ratio of cranberry juice to apple juice? A.1:20 B.

yarga [219]

20% of the juice is cranberry
80% of the juice is apple
Our ratio would be 20:80
We can simplify it and it will become
1:4

So your answer would be B. 1:4

I hope this helps :)

A, B, and C are collinear, and B is between A and C. The ratio of AB to AC is 1:2 If A is at (6,3) and B is at (-1,2), what are

Answer:

The coordinates of C is (-8,1)

Step-by-step explanation:

Looking at the attached image, you'd see that, AB is 1 and BC is 1, that's because we are told that ratio of AB to AC is 1:2 meaning, AC is 2 and AB is 1. Therefore for that ratio to be satisfied BC has to be 1 so that AC would be 2.

Now let's assume the coordinates of C is $(x,y)$ .
