Find three consecutive odd integers such as the sum of the smallest number and middle number is 27 less than 3 times the largest number
Answer:
17, 19 and 21Step-by-step explanation:
x - an integer
then: 2x is an even number and 2x+1 is an odd number
consecutive odd numbers increase by 2 (even numbers too)
so the next odd number (the middle number) is:
2x+1+2 = 2x+3
and the third (the largest) consecutive is:
2x+3+2 = 2x+5
the sum of the smallest and the middle numbers is:
2x + 1 + 2x + 3
3 times the largest number is:
3(2x + 5)
the sum of the smallest number and middle number is 27 less than 3 times the largest number, so:
2x + 1 + 2x + 3 = 3(2x + 5) - 27
4x + 4 = 6x + 15 - 27
-6x -6x
-2x + 4 = -12
-4 -4
-2x = -16
÷(-2) ÷(-2)
x = 8
2x+1 = 2•8+1 = 17
2x+3 = 2•8+3 = 19
2x+5 = 2•8+5 = 21
Check:
2x+1+2x+3 = 16+1+16+3 = 36
36+27 = 63
63:3 = 21 = 2x+5

Vladimir buys 1.20 pounds of Skittles, 7/2 pounds of M&Ms, and 5.2 pounds of pretzels. If the candy cost $1.20 a pound and the pretzels cost $1.10 a pound, how much did Vladimir spend?
Answer:
$11.36
Step-by-step explanation:
1.20 x 1.20= 1.44
7/2 x 1.20= 4.2
1.44 + 4.2= 5.64
5.2 x 1.10= 5.72
5.64 + 5.72= 11.36

Miki has 104 nickels and 88 dimes. She wants to divide her coins into groups where each group has the same number of nickels and the same number of dimes. What is the largest number of groups she can have?
Given :
Miki has 104 nickels and 88 dimes.
She wants to divide her coins into groups where each group has the same number of nickels and the same number of dimes.
To Find :
Largest number of groups she can have .
Solution :
In the given question we need to find the largest number of groups she can have i.e we have to find the LCM of 104 and 88 .
Now , factorizing both of them , we get :
[tex]104=1\times 2\times 2\times 2\times 13[/tex]
[tex]88=1\times 2\times 2\times 2\times 11[/tex]
Form above , we can say that common factors are :
[tex]HCF=2\times 2\times 2=8[/tex]
Therefore , the largest number of groups she can have is 8 .
Hence , this is the required solution .

Lupe had $100 to buy party supplies for her little sister's birthday. She bought 12 bags of party favors and 15 party hats. Each bag of party favors cost $5.30, and each party hat cost $1.95. How much money did Lupe have left after her purchases? $7.15 $20.50 $36.40 $65.75
Answer:
He had 7.15 dollars left over
Step-by-step explanation:
12 x 5.3 = 63.6
15 x 1.95 = 29.25
63.6 + 29.25 = 92.85
100 - 92.85 = 7.15
hope this helps you :)
pls mark brainlest ;)
The money left with Lupe after her purchase is $7.15.
Given,
Lupe had $100 to buy party supplies for her little sister's birthday.
She bought 12 bags of party favors and 15 party hats.
Each bag of party favors costs $5.30.
Each party hat cost $1.95.
We need to find how much money Lupe has left after her purchases.
How do we find the amount left after spending from the total amount?We will subtract the amount spent from the total amount given.
The number of spending may depend on the number of items bought and the cost of each item.
If one item cost = $a
And number of items bought = 2
The total amount spent = 2 x $a = $2a
Find the amount Lupe has.
= $100
Find the cost of one party bag.
= $5.30
Find the cost of one party hat.
= $1.95
Find the number of the party bags.
= 12
Find the number of the party hats.
= 15
Find the cost of 12 party bags.
= 12 x $5.30
= $63.6
Find the cost of 15 party hats.
= 15 x $1.95
= $29.25
Find the money left.
= $100 - ($63.6 + $29.25)
= $100 - $92.85
= $7.15
Thus the money left with Lupe after her purchase is $7.15.

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To determine which of the options is a factor of x² + 8x - 48,
We can use either factoring or the quadratic formula.
First, let's try factoring:
x² + 8x - 48 = 0
We need to find two numbers that multiply to -48 and add to 8.
One possible pair of numbers is 12 and -4:
(x + 12)(x - 4) = 0
Now we can see that x = -12 or x = 4 are the solutions to the equation. None of the options given match these solutions.

The factors of the expression are:
(x + 12) and (x - 4).

Linda just turned 15 and is planning to go to college. She has researched her favorite Texas university and discovered the tuition there is around $14,000 per year. From her 15th birthday, Linda received a $5000 gift that she will use for her first year of college tuition. Linda will begin her new part time job soon and wants to save money every month for the next 3 years to also contribute to her first year of college. What is the minimum amount of money Linda needs to save in order to completely pay for her first year of college tuition?
Answer:
Linda needs to raise a minimum of $9,000 to completely pay for her tuition fee for the first year, that is, $250 per month
Step-by-step explanation:
Tuition fee = $14,000 per year
Linda received a $5000 gift that she will use for her first year of college tuition during her 15th birthday
Amount remaining = Tuition fee - gift money received
= $14,000 - $5,000
= $9,000
Linda needs to raise $9,000 in the next three years to contribute to her first year of college tuition
The minimum amount Linda needs to save each month in the next three years to raise $9,000
= Remaining tuition / 3 years
= $9,000 / 3 * 12 months
= $9,000 / 36 months
= $250 per month
