Answer 1

Answer:

Dalai have 45 marbles.

Step-by-step explanation:

Consider the provided information.

Dalai bought a few swirl marbles and divided it equally among four of her friends and her brother, Jake. while playing, Jake lost two marbles and has only 7 marbles at present.

Let x is the number of marbles Dalai have.

She divide x number of marbles into 5 equal part (Four of friend and her brother)

That means each of them have $\frac{x}{5}$ marbles.

Jake lost two marbles out of $\frac{x}{5}$ and now he has only 7 marbles,

This can be represented as:

$\frac{x}{5}-2=7$

Solve the equation for x.

$\frac{x}{5}=7+2$

$\frac{x}{5}=9$

$x=45$

Hence, Dalai have 45 marbles.

Answer 2

45?

9 marbles x 5 (four of her friends plus jake)
