Mark and don are planning to sell each of their marble collections at a garage sale. if don has 2 more than 4 times the number o

Sonbull [250]

If the total number of marbles is 102, Mark has 20 marbles while Don has 82 marbles.

To answer this word problem, read and understand first the problem.

"Don has 2 more than 4 times the number of marbles Mark has."

Out of this statement, we can come up with the expression,

Don = 2 + (4 x Mark) (equation 1)

Next, the total number of marbles they have is 102.

Don + Mark = 102 (equation 2)

From this expression, if we subtract the number of marbles Mark has from the total number, we can get the number of marbles Don has.

Don = 102 - Mark (equation 3)

Equating the 1st and 3rd equation,

Don = 2 + (4 x Mark) = 102 - Mark

2 + (4 x Mark) = 102 - Mark

let x = Mark's

2 + (4x) = 102 - x

4x + x = 102 - 2

5x = 100

x = 20

Mark has 20 marbles.

Meanwhile, use either the 1st or 3rd equation to know the number of marbles Don has.

Don = 102 - Mark (equation 3)

Don = 102 - 20

Don = 82

A container of coffee is 1/6 full. That container contains 2/3 of a pound of coffee write a division expression that represents

Marizza181 [45]

Let us assume total capacity of the container = x pounds.

Container contains 1/6th coffee of total x pounds, that is x/6 pounds.

We also given that 1/6th part is equal to 2/3 of a pound.

So, we could setup an equation now.

x/6 pounds equals 2/3 of a pound.

$\frac{x}{6} = \frac{2}{3}$

Dividing both sides by 1/6, we get

$\frac{x}{6}$ ÷ $\frac{1}{6}$ = $\frac{2}{3}$ ÷ $\frac{1}{6}$ .

Therefore, x = $\frac{2}{3}$ ÷ $\frac{1}{6}$

Division expression that represents the capacity of the container = 2/3 ÷ 1/6.

Ben ran 3/10 of a mile. Shelly ran 8/10 of a mile. How many more miles did Shelly run than Ben? A) 11/10 B) 11/20 C) 5/0 D) 5/10

attashe74 [19]

Hello there! Shelly ran D) 5/10 more miles than Ben.

To find the difference between the two runner's distances, subtract the smaller distance from the greater distance.

8/10 - 3/10 = 5/10

Since there is a difference of 5/10, this means Shelly ran 5/1 more miles.

I hope this helps, & have a great rest of your day! :)
