A bag contains 40 marbles, some white some red. The ratio of white marblesto red ones is 1:7. How many red marbles are there?

1 answer:

7 0

The ratio is 1:7. This means there are 8 total parts. Start by dividing 40 by 8. This equals 5. Each part equals five, so the white marbles are 5. However, question asks for the number of RED. 7 of the 8 parts are red. 7*5 is 35 so there are 35 red marbles.

Answer:

y=29

Step-by-step explanation:

Since the angles are across a vertex from one another, they are congruent and equal. You can also see this by reflecting or folding it in half through the vertex. They will be the same. This means we can write the following equation and solve using inverse operations:

4y-8=79+y

4y-y-8=79+y-y

3y-8=79

3y-8+8=79+8

3y=87

y=29
