Steps:

Sam = m years old

Sum of their ages means we add them up

m+(m+5) = m+m+5 = (m+m)+5 = 2m+5

True or false? All irrational numbers have some repeating pattern which can

alexgriva [62]

Answer:

Given statement is false.

Step-by-step explanation:

Given that,

All irrational numbers have some repeating pattern which can be used to compare them to rational numbers.

We know that,

Rational number :

A rational number is defined such a number which can be written as a ratio.

It means we can write a rational number as a fraction.

For example : 2, 3/2 and 4/2... etc.

In the fraction, both number are4 whole number.

So, we can say that, a number which can be define as a fraction it is called rational number.

Irrational number :

An irrational number is defined such a number which can not be written as a ratio.

For example : √5, √10 and √15...etc

So, we can say that, a number which can not be define as a fraction it is called irrational number.

We need to find all irrational numbers have some repeating pattern which can be used to compare them to rational numbers

According to rational number and irrational number

This statement is false.

Suppose, √2 is irrational but not repeating.

So, we can't write √2 as rational number.

Hence, Given statement is false.

The equations that could represent the quantities and constraints in this situation are:

m = 12(15) ⇒ answer a

4n = c ⇒ answer c

b = 2(3) + 3(4.50) ⇒ answer e

Step-by-step explanation:

Jada plans to serve milk and healthy cookies for a book club meeting

She is preparing 12 ounces of milk and 4 cookies per person
There are 15 people in the club
A package of cookies contains 24 cookies and costs $4.50
A 1-gallon jug of milk contains 128 ounces and costs $3

n represents number of people in the club,

m represents the ounces of milk

c represents the number of cookies

b represents Jada's budget in dollars

∵ m represents the ounces of milk

∵ She is preparing 12 ounces of milk

∵ There are 15 person in the club

∴ m = 12(15)

∵ She is preparing 4 cookies per person

∵ c represents the number of cookies

∵ n represents the number of people in the club

∴ 4n = c

∵ A package of cookies contains 24 cookies

∵ She needs = 15 × 4 = 60 cookies

∵ 60 ÷ 24 = 2.5

∴ She needs to buy 3 packages of cookies

∵ She needs = 15 × 12 = 180 ounces of milk

∵ A 1-gallon jug of milk contains 128 ounces

∵ 180 ÷ 128 = 1.406

∴ She needs to buy 2 A 1-gallon jug of milk

∵ The cost of each jug of milk is $3

∵ The cost of each package of cookies is $4.50

∵ b represents Jada's budget in dollars

∴ b = 2(3) + 3(4.50)

The equations that could represent the quantities and constraints in this situation are:

m = 12(15) ⇒ answer a

4n = c ⇒ answer c

b = 2(3) + 3(4.50) ⇒ answer e
