Find 3 consecutive odd integers whose sum is 225, explain please
aleksklad [387]
3 odd integers have a property that they average up to the middle large one. Let's say we have 3, 5, and 7. 3 is 2 less than 5 and 7 is 2 more than 5. so when you add them it equals 2 times 5. 
After we know that, the sum of 3 odd integers is just 3 times the middle number. ex. 3+5+7 = 3 times 5 = 15
Then we know the some number times three = 225. we find out that the middle number is 75, so the other two are 73 and 77

Use order of operations, or PEMDAS which stands for Parenthesis, Exponent, Division, Addition, and Subtraction.

Do those operations in that order. Can you try?

#19 please I’m literally failing math
ankoles [38]

Answer:

$51.12

Step-by-step explanation:

Hello there!

In number 19, we want to find the total price of a sweatshirt that costs $48 dollars but has 6.5% sales tax

Sales tax is a small percentage of the cost of an item that is added to items when they are being sold.

In this problem, 6.5% of the cost of the sweatshirt will be added to the cost of the sweatshirt in the form of sales tax. The price of the sweatshirt plus the amount in sales tax will be the total cost of the sweatshirt.

Translating that as an equation,

48 + 48*6.5%=total cost

You can calculate 48*6.5% as \frac{48*6.5}{100}, which is equal to 3.12

So that means that $3.12 will be added to the cost of the sweatshirt.

Therefore,

48 + 3.12=<u>$51.12</u>, which will be the total cost of the sweatshirt, including sales tax

Hope this helps!
