Eight burgers and three orders of fries cost $79.49. Six orders of fries and twelve burgers cost $125.82.Find the price of one burger and one order of fries .
Answer:
Burgers - $8.29 and fries - $4.39Step-by-step explanation:
Let burgers - b, fries - f
8b + 3f = 79.4912b + 6f = 125.82Double the first equation and subtract the second equation:
16b + 6f - 12b - 6f = 2(79.49) - 125.824b = 33.16b = 33.16/4b = 8.29Find f:
8(8.29) + 3f = 79.493f = 79.49 - 66.323f = 13.17f = 13.17/3f = 4.39if theres 20 desks in 5 classes,What does it equal?

Find the area and perimeter of a rectangle that has a length of (x + 24) and (x + 16). Show all work for full credit.
Answer:
Perimeter of rectangle = 4x + 80
Area = x² + 40x + 384
Step-by-step explanation:
Perimeter of rectangle = 2*(length + width)
= 2* (x + 24 + x + 16)
= 2*( x +x + 24 + 16) {Combine like terms}
= 2* (2x + 40)
Use Distributive property : a*(b +c) = a *b + a*c
= 2*2x + 2*40
= 4x + 80
Area of rectangle = length * width
= (x + 24) (x + 16) {use FOIL method}
= x*x + x*16 + 24*x + 24*16
= x² + 16x + 24x + 384 {Combine like terms}
= x² + 40x + 384

Answer:
11259.5Step-by-step explanation:
25 × 386 + 3219 ÷ 2 = 9650 + 1609.5 = 11259.5Answer:
11259.5
Step-by-step explanation:
25×386+3219÷2
Multiply 25 and 386 to get 9650.
9650+3219/2
Convert 9650 to fraction 19300/2.
19300/2+3219/2
Since 19300/2 and 3219/2 have the same denominator, add them by adding their numerators.
19300+3219/2
Add 19300 and 3219 to get 22519.
22519/2
Divide 22519 by 2 to get 11259.5.
11259.5

A worker work for just 3 days in a one month and his 1 month salary is 4380 what is the 3 days pay ?
Answer:
$505.385
Step-by-step explanation:
Given that:
Worker's one month salary is 4380
The number of working days in the month is not given ; However the average number of working days in a month usually range from 22 to about 26 days
Lets assume the number of working days for the firm in question is 26 days
Daily salary will be calculated as :
Monthly salary / number of working days
4380 / 26
= 168.46153
3 days salary :
168.46153 * 3
= $505.385
The graphs of linear functions f and g are shown on the grid below.

Mary is buying a case of water. She spends $7.99 for a case of 24 bottles. What is the unit rate? (Cost for 1 bottle) *
Answer:
so I'm not 100% sure but in these types of questions you are supposed to divide
so you have a pack of 24 bottles for 7.99
so you would do 7.99÷24 = 0.33
then to check it you can multiply
0.33× 24 bottles and it gives you 7.93 which is super close to 7.99 anyway I hope this helps ...
A telecommunications company in a small town had 450 phone subscribers before they introduced a plan for newly joining members. The company recorded an approximate 50% increase each month in the number of new phone subscribers, where they had one new subscriber at the start of the plan. The number of phone subscribers x months after the plan was launched is modeled by the function below.
Answer:
450 x (1 + 0.5) ^ X = Phone subscribers
Step-by-step explanation:
Since a telecommunications company in a small town had 450 phone subscribers before they introduced a plan for newly joining members, and the company recorded an approximate 50% increase each month in the number of new phone subscribers, where they had one new subscriber at the start of the plan, to determine the number of phone subscribers x months after the plan was launched, the following function must be considered and solved:
450 x (1 + 0.5) ^ X = Phone subscribers
So, for example, in 3 months, the number of subscribers would be the following:
450 x (1 + 0.5) ^ 3 = 1,518.75
Thus, in 3 months, the company would have 1,518 subscribers.

(x + 2)x____= x² - 4
O x² – 4
OX-2
O x + 2
O x²-2
Answer:
x-2
Step-by-step explanation:
(x+2)× ___=(x+2)(x-2)
___=(x+2)(x-2)/(x+2)
___=x-2
The polynomial which should be filled in the blank is (x - 2).
What are Polynomials?Polynomials are mathematical expressions which consist of one or more terms involving variables and coefficients connected with operations like multiplication, subtraction, addition and natural number powers of variables.
Given that,
x² - 4 = (x + 2) (x - 2).
We have to find the blank space.
By commutative property, the other side is also equal.
That is,
(x + 2) (x - 2) = x² - 4
Hence the correct option is (x - 2).

Write an equation of the line that passes through (-4 , 2) and is parallel to the line
y = 1/4 + 1
SOLVE MY QUESTION PLEASE!!
I’LL PUT YOU IN BRAINLEST!!
Answer:
y=1/4x + 3
Step-by-step explanation:
We know that the beginning of the equation has to be 1/4x since the line has to be parallel. So what I did was start at -4,2 then go up 1 and over 4, which led me to 3 as the y intercept.
