Beverly has a bag of marbles that weighs 30 grams. She knows that each marble weighs 1.5 grams and the bag weighs 1.5 grams. Which equation could she use to determine how many marbles are in the bag? Select all that apply.
(1.5)x + 1.5 = 30
30 – x = 2(1.5)
(1.5)(30) = 1.5x
1.5 + x = 30
1.5x = 30 – 1.5
Answers
Answer:
The answer is (1.5)x + 1.5 = 30 and 1.5x = 30 - 1.5
In other words its A and E.
Option-A and option-E are correct that is 1.5x + 1.5 = 30 and 1.5x = 30 - 1.5 are the equation she use to determine.
Given that,
30 grams of marbles are in Beverly's bag. She is aware that both the bag and each stone weigh 1.5 grams.
We have to find which equation could she apply to calculate the quantity of marbles in the bag.
We know that,
What is equation?
A mathematical statement that uses the sign "equal to" between two expressions with equal values is called an equation.
Bag of marbles weight is 30 grams
Weight of a marble is 1.5 grams
Weight of bag is 1.5 grams
There are x marbles in the bag,
Then
1.5x + 1.5 = 30
1.5x = 30 - 1.5
Therefore, 1.5x + 1.5 = 30 and 1.5x = 30 - 1.5 are the equation.
