You are baking cupcakes for your class. There are 30 total students in your class and you have baked 15 cupcakes. Write andsolve an equation to find the additional number of cupcakes you need to bake in order to have 3 cupcakes for each student.
Write your equation so that the units on each side of the equation are cupcakes per student.
Equation:
= 3
Number of cupcakes: x=

Answers

Answer 1

Answer:

The equation is 3=(x+15)/30 and the number of additonal cupcakes to be made is 75.

What is equation?

An equation is a relationship between the variables and constants representing how they are related to each other. It includes equal to "=" sign.

It is known that each student will have 3 cupcakes. So, right side of the equation will be 3.

After 15 cupcakes, x more cupcakes are needed. So, the total number of cupcakes is x+15.

Since there are 30 students, the number of cupcakes per student will be (x+15)/30

Determine the equation and solve it.

(x+15)/30=3

x+15=90

x=75

So, 75 more cupcakes are needed to be baked.

draw an array to show how to arrange 20 chairs into 5 equal rows. Explain what each part of the array represents.

Answers

Since there are 20 chairs and should be arrange into 5 equal rows. So the number of chairs in each row is equal to 20 / 5 which equal to 4. so let x represent a chair in the array. so the drawing should be like:
x x x x
x x x x
x x x x
x x x x

A bag contains 2 white marbles and 7 purple marbles. Two marbles are drawn at random. One marble is drawn and not replaced. Then a second marble is drawn. What is the probability of selecting a purple marble and then a white marble? What is the probability of selecting two white marbles? Is there a greater chance of selecting two white marbles in a row or two purple marbles in a row? Show your work.

Answers

1. The probability of selecting a purple marble and then a white marble:
P ( P + W ) = 7/9 * 2/8 = 7/36
2. The probability of selecting two white marbles:
P( W + W ) = 2/9 * 1/8 = 1/36
3. P ( P +P ) = 7/9 * 6/8 = 21/36 = 7/12
The probability of selecting 2 purple marbles in a row is much greater than selecting two white marbles.

The probability of selecting a purple marble and then a white marble is 0.19.

The probability of selecting two white marbles is 0.03.

The probability of picking two purple marbles is greater.

What are the probabilities?

Probability is used to determine the likelihood that an event would occur.

The probability of selecting a purple marble and then a white marble = (number of purple marbles / total number of marbles) x (number of white marbles / total number of marbles- 1)

7/9 x 2/8 = 0.19

The probability of selecting two white marbles = (number of white marbles / total number of marbles) X (number of white marbles / total number of marbles- 1)

2/9 X 1/8 = 0.03

The probability of selecting two purple marbles = 7/9 x 6/8 = 0.58
