Answer:
96 = x
Step-by-step explanation:
I'm going to use cents instead of dollars because I find decimals and fractions to be cumbersome. I assume you meant $.005 instead of 4.005.
Let x denote the price (in cents) of the 12-ounce can. Then the price of the 16-ounce can is (x + 16) cents, and the price of the 24-ounce can is ((x + 16) + 68), or (x + 84) cents.
The unit price (cents per ounce) of the 12-oz can is x/12
The unit price of the 16-oz can is (x + 16)/16
The unit price of the 24-oz can is (x + 84)/24
You are told that, in terms of x,
(x + 84)/24 = x/12 - 0.5
Multiply both sides by 24:
x + 84 = 2x - 12
Solve for x:
96 = x
So the unit prices (in cents per ounce) are:
12 oz: 96/12 = 8 cents/oz
16 oz: 112/16 = 7 cents/oz
24 oz: 180/24 = 7.5 cents/oz
So the 16 ounce can is the best buy based on lowest unit price.
In this exercise we have to use the knowledge of finance to calculate the best price to be offered, in this way:
[tex]12 oz: 96/12 = 8 cents/oz\\16 oz: 112/16 = 7 cents/oz\\24 oz: 180/24 = 7.5 cents/oz[/tex]
Some values should be simplified as they were informed in the statement:
The unit price (cents per ounce) of the 12-oz can is x/12The unit price of the 16-oz can is (x + 16)/16The unit price of the 24-oz can is (x + 84)/24So putting together an equation with these values and terms informed we find that:
[tex](X + 84)/24 = X/12 - 0.5\\X + 84 = 2X - 12\\X=96[/tex]
So with the value of X found it is only necessary to use the previous equations and replace this value.

victor are 60 de lei si merge la florarie pentru a-i cumpara mamei sale un buchet de flori. daca ar cumpara 9 garoafe si 4 trandafiri, ar plati 47 de lei. daca ar cumpara doar trandafiri, toti banii i-ar ajunge pentru 12 bucati. insa el cumpara 13 flori (garoafe si trandafiri) si ramane cu 5 lei rest, cate garoafe si cati trandafiri a cumparat victor?
Answer:
Număr de trandafiri = x = 5 trandafiri
Numărul este garoafe = y = 8 garoafe
Step-by-step explanation:
Pasul 1
Să reprezentăm:
Costul garoafelor = c
Costul trandafirilor = r
Victor are 60 de lei și merge la florărie să-i cumpere mamei sale un buchet de flori.
Dacă ar cumpăra 9 garoafe și 4 trandafiri, ar plăti 47 de lei.
Prin urmare,
9c + 4r = 47 ..... Ecuația 1
Dacă ar cumpăra doar trandafiri, toți banii ar fi suficienți pentru 12 bucăți.
Prin urmare,
12 trandafiri = 60 lei
1 trandafir = r lei
Cross Multiply
12r = 60 lei
r = 60 lei / 12
r = 5 lei
1 trandafir costă 5 lei
Înlocuim 5 cu r în ecuația 1
9c + 4 × 5 = 47
9c + 20 = 47
Colectează ca termeni
9c = 47 - 20
9c = 27
c = 27/9
c = 3 lei
Costul unei garoafe este de 3 lei
Pasul 2
Dar cumpără 13 flori (garoafe și trandafiri) și rămâne cu 5 lei rămași,
60 lei - 5 lei = 55 lei
Asta înseamnă că a cheltuit 55 de lei pe 13 flori.
Lasă
Număr de trandafiri = x
Numărul este garoafe = y
x + y = 13 ......... Ecuația 1
x = 13 - y
Din moment ce, Costul unei garoafe = 3 lei și 1 trandafir = 5 lei
3x + 5y = 55 ...... Ecuația 2
Înlocuim 13 - y cu x în ecuația 2
3x + 5y = 55
3 (13 - y) + 5y = 55
39 - 3y + 5y = 55
Colectează ca termeni
- 3y + 5y = 55 - 39
2y = 16
y = 16/2
y = 8
Rezolvarea pentru x
x = 13 - y
x = 13 - 8
x = 5
Prin urmare:
Număr de trandafiri = x = 5 trandafiri
Numărul este garoafe = y = 8 garoafe

What is mArc SU?
49°
77°
98°
161°
Answer:
77°
Step-by-step explanation:
By the property of intersecting tangent and secant outside of a circle:
[tex]21 \degree = \frac{1}{2} ( 119 \degree - \widehat{SU} ) \\ \\ 42 \degree = 119 \degree - \widehat{SU} \\ \\ \widehat{SU} =119 \degree - 42 \degree \\ \\ \widehat{SU} =77\degree \\ \\ [/tex]
The mArc SU is option (B) 77 degrees
What is Tangent?A straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.
What is secant ?A secant is a line that intersects a circle in exactly two points.
Here,
By the property of intersecting tangent and secant outside of a circle:
[tex]T=\frac{1}{2}(RU-SU)[/tex]
Here
T= 21 degrees
RU is the mArc RU = 119 degrees
Then,
[tex]21 =\frac{1}{2}(119-SU)\\ 42=119-SU\\SU=119-42[/tex]
SU = 77 degrees
Hence, the mArc SU is option (B) 77 degrees

Answer:
Number of terms.
A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.
A binomial has two terms. For example: 5x2 -4x
A trinomial has three terms. For example: 3y2+5y-2
Any polynomial with four or more terms is just called a polynomial. For example: 2y5+ 7y3- 5y2+9y-2

Answer:
The fourth choice, Pink, is the correct answer.
Step-by-step explanation:
The first two options intersect, therefore the intersection is the solution. The third set of lines may seem like one line, however since we are dealing with two linear equations, it can be presumed that those are two lines on top of one another, therefore it has infinite solutions. The last option remaining is Pink, in which the lines are parallel and therefore will never intersect, making them have no solution.

63/4 ÷ 7
9/4

Answer:
2 1/4 pounds each
Step-by-step explanation:
Convert 15 1/4 into a decimal (15.75) then divide by seven (15.75 ÷ 7 = 2.25)
