Question

The number of yellow marbles in a bag is 10 more than 2 times the number of blue marbles. The table shows how the number of yellow marbles, y, depends on the number of blue marbles, b. Choose the equation which represents the rule.

A) y = 2b − 2
B) y = 10 − 2b
C) y = 2b − 10
D) y = 2b + 10

Answer 1

D.

`y = 2b + 10`

Answer 2

Answer: D)
`y=2b+10`

Explanation:

Let b be the number of blue marbles.

Given statement: The number of yellow marbles in a bag is 10 more than 2 times the number of blue marbles.

Here, 2 times of blue marbles =
`2* b =2b`

Then according to the given rule , the equation to represent the number of yellow marbles 'y' is given by :-

`y=2b+10`
