Answer: 40

Step-by-step explanation:

Let the two numbers be a and b.

Therefore,

a - b = 3 ....... i

a + b = 13 ....... ii

From equation I, a = 3 + b

Put a = 3+b into equation ii

a + b = 13

3 + b + b = 13

3 + 2b = 13

2b = 13 - 3

2b = 10

b = 10/2

b = 5

Since a = 3 + b

a = 3 + 5

a = 8

The product of the numbers will be:

= 8 × 5

= 40

PLEASE HELP! Oscar and Kim have $22.00 each to spend at a book fair, where all students receive a 30% discount. They both want t

babymother [125]

Answer:

Both of them correct.

$21.945

They have enough money to purchase the book

Step-by-step explanation:

Oscar takes 30% of the normal price and subtracts it from the normal price. Out of 100% price he takes 30% so the result is: 100-30%= 70% of the normal price. Oscar's first step has the same result as Kim.

Oscar takes 10% of the discounted price (70%) and adds it back. The price will become 70% + 10%*70%= 77% of original price. Kim multiplies the discounted price with 110%, so the price will be: 70% * 110%= 77%. Both also give the same result.

The final price is 77% of the original, it will be: $28.50* 77%= $21.945

Both of them can buy the book

Angelina_Jolie [31]

Answer:

The inequality is $0.75x\geq y$

Step-by-step explanation:

Given : Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. If x is the number of days that Lionel practices and y is the total number of hours he spends practicing.

To find : Which inequality represents this situation?

Solution : He plays trumpet for a minimum of 45 minutes

$45 \text{minutes}=\frac{45}{60}=\frac{3}{4}=0.75\text{hours}$

If x is the number of days that Lionel practices then he practices for at least

$=0.75x$ hours

y is the total number of hours he spends practicing

So, the inequality form is:

$0.75x\geq y$

i.e, 0.75x is greater than y.
