Mathematics
2 answers:
madreJ [45]3 years ago

Answer:

The value of y is 4

Step-by-step explanation:

If the some of the counters in each box are the same, then A = B

If A is 8y + 1 and B is 6y + 9

Since A = B, we can say

8y + 1 = 6y + 9

Collecting like terms, we will have

8y - 6y = 9 - 1

2y = 8

Dividing both sides by 2, we will have

y = 8/2

y = 4

2y=8-Take one over by -1

y=4-Divide 8 by 2 to get y=4

gavmur [86]

Answer:

2\frac{4}{5}\ \ or \ 2.8 \ \ cups

Step-by-step explanation:

-The total portion fed to the dog is 7/10 cup
