______________________________
1.) Fill in the given variables into a new equation: [tex]r=2[/tex][tex]t=-7[/tex][tex]u=-5[/tex][tex]3(2+(-5))[/tex]- We do this since it gives us the missing variables, which makes it so we can solve it like any regular equation.
Equation at the end of Step 1:
[tex]3(2+(-5))[/tex]2.) Subtract 5 from 2:[tex]2-5=-3[/tex]- We do this because we need 1 number, not 2 at the end.
Equation at the end of Step 2:
[tex]3(-3)[/tex]3.) Multiply 3 and −3:[tex]3[/tex] × [tex]-3=-9[/tex]______________________________

At a grocery store you can purchase loose lemons at 2 for $0.99. You can also buy a bag of 6 lemons for $2.50. Which is the better buy? Be sure to show the unit cost for each
Answer:
Bag of lemon
Step-by-step explanation:
Given that:
Cost of loose lemon = $0.99 for 2
Cost of bag of lemon = $2.50 for 6
Calculating the cost per 1 for loose and bag of lemon (unit cost) ;
Loose lemon :
$0.99 /2 = $0.495
Bagged lemon :
$2.50 / 6 = $0.4167
Hence, since the unit cost of bagged lemon is lesser than loose lemon, then purchasing a bag of lemon is better

Solve the compound inequality: n+1<=-3 or -4n<-8
Answer:
-4n<-8 the answer for this is (n>2)
n+1<=-3 the answer for this is (n<=-4)
The value of n is less than equal to negative 4 and greater than 2. n ≤ –4 and n > 2.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The inequalities are given below.
n + 1 ≤ –3 …1
–4n < –8 …2
On solving equation 1, we have
n + 1 ≤ –3

HELP WILL MARK BRAINLIEST PLEASE ANSWER ALL THREE
Step-by-step explanation:
8. ∠COB and ∠AOD are vertical angles or C
9. Vertical angles are equivalent to each other so 4x-16 = 112°
4x - 16 = 112°
4x - 16 + 16 = 112 + 16
4x = 128
4x/4 = 128/4
x= 32° or D
10. ∠AOC is vertical to ∠DOB therefore the 2 angles are congruent
You can do 360 - (112 + 112) = 2AOC
360 - 224 = 2AOC
136 = 2AOC
AOC = 68°or A
OR
You could just do 180 -112
Since ∠AOD and ∠AOC are supplementary angles, they both add up to 180°
We already know the measure of ∠AOD, it's 112°
So all you would need to do is subtract 112 from 180
And you get 68° or A

How much vanilla extract will be needed to make 2 frozen cookies? Show your work.
If you only want to make 9 cookies ( 0.75 of a dozen ) how much quick cooking oats do you need?
How many cups of flour would you need to make 3 dozen cookies?
Answer:
2 teaspoons for the two frozen cookies
3/4 a cup for the cooking oats
2 cups for the flour
Step-by-step explanation:
First Question
The recipe makes 18 cookies. Divide the cookies by 9, half of the batch, to get 2. Now all you have to do is devide the amount of vanilla extract by 9, it will give you two teaspoons.
Second Question1 and 1/2 devided by two since you're devidng the recpie by two to get 9 cookies. A cup is four so 3/4 plus 3/4 equals 6/4. Simplified it'd be 1 and 1/2 or 1 and 2/4.
Third QuestionThe recipe already calls for 1 and 1/2 a dozen. All you're doing is multiplying the recipe b two to get 3 dozen cookies. Now focusing our attention to the flour, there is 1 cup for 1 and 1/2. Multiply 1 by 2 since there is already half of the recipe here. 1 and 1/2 + 1 and 1/2 is 3 so there'd be 2 cups. Basically just double the recipe.

For the expression StartFraction 15 x cubed + 25 x squared + 5 x + 2 Over (5 x squared + 1) squared EndFraction, which sum represents the correct form of the partial fraction decomposition?
Answer:
StartFraction 15 x cubed + 25 x squared + 5 x + 2 Over (5 x squared + 1) squared EndFraction, can be written in mathematical form as
Let y = [tex]\frac{15 x^3 + 25x^2 +5x+2}{({5x^2+1})^2}[/tex]
on expanding [tex]{({5x^2+1})^2 = 25x^4 +1 + 10x^2[/tex]

Solve The Equation
1/7 (63n - 77) = -11 + 9n
A. No Solution
B. n = 0
C. Infinite Solutions
D. n = 11/9
E. n = -11/9
Answer:
C. Infinite Solutions
Step-by-step explanation:
In order to solve this we fist have to simplify the equation so we do the following:
[tex]\frac{1}{7}(63n -77) = -11 + 9n\\\\(\frac{1}{7})(7)(63n - 77) = (7)(-11 + 9n) \\\\63n - 77 = -77 + 63n\\63n - 77 = 63n - 77[/tex]
From here we know that any value of n is the solution of this equation so the answer is option C.
Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah, a total of 10 people took the trip. She was able to purchase coach tickets for $320 and first-class tickets for $960. She used her total budget for airfare for the trip, which was $4480. How many first-class tickets did she buy? How many coach tickets did she buy?
Answer:
she bought 8 coach, 2 first-class
Step-by-step explanation:
let x = number of coach tickets
equation I used: 320x + 960(10 - x) = 4480
320x + 9600 - 960x = 4480
-640x = -5120
x = 8
In a candy store in California using a 6% tax sale, three jars of candy are labeled $35.00 after tax. What is the sale price of each jar of candy after tax?
Answer:
Step-by-step explanation:
You first have to find 6% of 35. Which is 2.1 and so you then multiply 2.1×3 which is 6.3 and then subtract 6.3 from 35. 35-6.3 which is 28.7 and then divide that by 3. Which is essentially 9.6 if you round up the decimal. Otherwise it'd just be 9.566667. So, I'd say each is 9.6 or 10 if you're rounding for the nearest whole number.

Step-by-step explanation:
Will give brainliest!!! The MTC Theater holds 250 people, and last night’s performance sold out! Students under the age of 16 paid $2.50 per ticket, while everyone else paid $4.00 per ticket. Last night’s show brought in $910.
Write a system to represent the given equations.
How many adult tickets were sold?
How many under the age of 16 tickets sold
Answer:
Student's tickets: 60
Adult's tickets: 190
I think this is right
Step-by-step explanation:
"Let x represent the number of tickets sold to students under the age of 16. Let y represent those over the age of 16.
Equation 1, number of tickets sold:
The total number of tickets sold to students under the age of 16 plus the number of tickets sold to students over 16 must equal 250 (since the theater was sold out). The equation becomes:
x + y = 250
Equation 2, revenue from tickets sold.
The total revenue was $910. The cost of tickets under 16 is $2.50 and the cost of tickets over 16 is $4.00. The equation becomes:
2.50 * x + 4.00 * y = 910.00
The system of equations to solve is:
x + y = 250
2.50 * x + 4.00 * y = 910.00 "

C= 2 x 3.14 x 12.5
C= 78.5in
Answer:
78.5
Step-by-step explanation:
To find circumference, you need to multiply radius (r) times pi (3.14 or 22/7) times 2. So, you would do 12.5 times 2 times 3.14. You would get 78.5.
