Answer: 1 1/6
Step-by-step explanation:
Let the amount of students that a bottle of juice can cater for be x. Therefore,
2/3 × x = 12
2x/3= 12
2x = 12 × 3
2x = 36
x = 36/2
x = 18
Since Mrs. Williams gave juice to 21 students, the number of bottles of juice that was used will be:
= 21/18
= 1 3/18
= 1 1/6
From 20 tons to 99 tons? Increase or decrease?
Answer:
increase in weight
Step-by-step explanation:
Answer:
Increase.
Step-by-step explanation:
20 is larger than 99. if one ton is 2000 pounds then 20 tons are 40,000 pounds. So 99 times 2000 is 198,000 pounds, which is larger than 40,000.
Summary: 20 tons (40,000 pounds) < 99 tons (198,000) pounds

Answer:
So for each point's numbers you have the x and the y. The first is the x, 2nd y in the parenthesis.
On the graph you start with the x axis, x in the middle is 0 to the left is the negative #'s and on the right: positive. Y axis is top positive, bottom negative! Now put the numbers on the axis' and then plot the points!

What is the slope of the line y= -121x + 200 ??
Answer:
Slope = - 121
Step-by-step explanation:
Step 1:
y = mx + b Slope Intercept Form
Step 2:
m = Slope
Step 3:
y = - 121x + 200 Equation
Answer:
Slope = - 121
Hope This Helps :)
Answer:
-121X
Step-by-step explanation:
In an equation, x= the slope, and the number that comes after is the y intercept. So 200 would be where the line starts, and would have a negative slope of -121x
I hope this helps! :)

Answer:
where a is in the equation put 6.05 and where b is put 3.611
Step-by-step explanation:
-6.05 + (-3.611)
-6.05 - 3.611
-9.661
Answer:
-9.661
Step-by-step explanation:
First of you want to plug in a and b making the equation
-6.05 + (-3.611)
or
-6.05 - 3.611
*I hope your teacher will allow you to use a calculator because of the decimals
Then you will add -6.05 + (-3.611) together
to get a negative answer of...
-9.661
Michael is buying a new pair of headphones from an electronics store. The headphones cost $15.50, but Michael has a coupon that will reduce the cost by $4.00. He must pay 6% sales tax on the discounted price of the headphones. How much will Michael pay in total for the headphones, including tax?
Answer: Michael pays $12.19 for the headphones including the tax.
Step-by-step explanation:
The initial price of the headphones was $15.50
When Michael uses his coupon, the price is decreased by $4, then the new price will be:
$15.50 - $4 = $11.50
Now Michael must pay 6% for taxes (on the discounted price), then he must pay:
$11.50 + (6%/100%)*$11.50
$11.50 + 0.06*$11.50
$11.50*1.06 = $12.19
Then Michael pays $12.19 for the headphones including tax.

Answer: 2.)non function 3.)non function 4.) function 5.)non function 6.) non function 7.)function 8.)non function PART B 1.)non function 2.)function 3.) function
Step-by-step explanation: a function is when the domain (x) all each have one answer like (-2.6)(7,4)(8,6) there can be repeating ranges (y) just not domains.
A non function is when one domain (x) has multiple ranges(y) like (7,2)(-9,6)(7,9) the 7 repeats twice giving it two ranges, which causes it to be non functional. hope that helped :))
You are planning a skating party at a rink that charges a basic fee of
$10.00 and $6.00 per person for catered parties. You don't want to spend
more than $52.00. Write and solve an inequality to find the number of
friends you can invite.
a. 6x + 10 < 52; x< 7
6. 6x + 10 > 52; <> 7
C. 6% + 10 > 52; 2 >7
d. 6x + 10 < 52; x < 7
Answer:
y = 6.50x + 6 or 71 = 6.50x + 6
10 people are the max you can invite
Step-by-step explanation:
We have the simple equation
y = 6.50x + 6
6.50x because it it per person
6 because it is a flat one time charge
We want the max to be 71 so that will be our y
71 = 6.50x + 6
We are now going to solve for x
65 = 6.5x
x = 10
Hope it helps! (:

Jing just got a new job. She started at a pay rate of $12.50 per hour and will get a $0.50 raise each year. Max started a job where is salary is found by the equation y=x+10, where x is the number of years. What is the initial value for Jing?
Answer:
initial value for Jing is $12.50.
Step-by-step explanation:
It is given that Jing started at a pay rate of $12.50 per hour and will get $0.50 per year. So, 0.50 is slope and y intercept is 12.50 for this equation.
The y intercept represents the initial value for the Jing.
So, initial value is $12.50.

Solve for x
Please show the steps
The answer is 10
Answer:
x = 10
Step-by-step explanation:
Since ΔCDE ~ ΔQRS, we can find the actual length of x + 8 first before finding the value of x.
Length of x + 8 = [tex]\frac{12}{20}[/tex] × 30
= 18
x + 8 = 18
x = 18 - 8
x = 10

Answer:
Agriculture
Step-by-step explanation:
Quadratic equations are also used in agriculture. One of these uses is in finding out the optimal arrangement of boundaries to produce the biggest fields and pens given the materials on hand. Area is the length of a surface multiplied by its width. This turns calculations involving areas into quadratic equations.

Answer:
x = 23
Step-by-step explanation:
Eliminate parentheses, separate the variables and the constants, divide by the coefficient of the variable.
7(x +4) = 9(x -2) . . . . . given
7x +28 = 9x -18 . . . . . eliminate parentheses using the distributive property
28 = 2x -18 . . . . . . . . . subtract 7x*
46 = 2x . . . . . . . . . . . . add 18
23 = x . . . . . . . . . . . . . divide by 2
The solution is x = 23.
Check
7(23+4) = 9(23-2) ⇒ 7·27 = 9·21 . . . true (=189)
__
* We choose to subtract 7x instead of 9x so that the resulting x-term has a positive coefficient.
_____
Additional comments
The properties of equality tell you that you can do anything you like to an equation, as long as you do the same thing to both sides of the equation. So, when we say "subtract 7x", we mean that value is subtracted from both sides of the equation. Subtracting a value, or adding its opposite, is a way to remove a term from a place in the equation where you don't want it.
Here, the smaller x-coefficient is on the left, so we choose that term to subtract. That leaves the remaining x-term on the right (with a positive coefficient). We don't want any constants there, so we add the opposite of that constant. (The opposite of -18 is 18, so that is what we add--to both sides.)
__
Sometimes you will be told differently. You will be told to "put that over there and change its sign" or "cross-multiply". These instructions are based on appearance. The fundamental, always-applicable rule is "do the same thing to both sides of the equation." With practice and understanding, you can begin to think in terms of these shortcut suggestions.
