Answer:

14 (exactly 500) or 15 (over 500)

Step-by-step explanation:

We know that Alexis has already bought 50 stamps.

50 + 30 = 80

We need to subtract to see how many stamps she needs.

500 - 80 = 420

We divide by 30 to see about how many weeks it would take.

420 / 30 = 14

We can add 1 more week because she wants to have more than 500 stamps.

hope this helps :)

Rani is making rice pudding. She uses
Goryan [66]

Rani will use 3/2 cups of white rice for 3 cups of milk.

<h3>What is termed as unitary method?</h3>

"It is a method in which we obtain the value of a single unit by subtracting the value of multiple units and thus the value of multiple units by subtracting the value of a single unit."

  • The value of several things is given in the unitary method, and we must either figure out the significance of more or lesser things.
  • To do so, we must first determine the value of one item by division and then determine the value of ever more or fewer items by multiplication.

Now, for the given question;

1 cup of white rice is required for every 2 cups of milk by Rani.

Thus,

2 cups of milk ------> 1 cup of white rice.

So, using unitary method. Divide both side by 2.

1 cups of milk ------> 1/2 cup of white rice.

Now, calculate for the 3 cups of milk.

multiplying both side by 3.

3 cups of milk ------> 3/2 cup of white rice.

Therefore, the 3/2 cups of white rice required for the 3 cups of milk.

What is the answer for 2(a+b)=
Rainbow [258]
<h3>It is equivalent to 2a+2b</h3>

We use the distributive property.

Multiply the outer term 2 by each term inside ('a' and b)

2 times a = 2a

2 times b = 2b

We add those results to get 2a+2b. We cannot combine these terms as they are not like terms.
