5y + 2(11 - 4y) = 82 + y
Help Needed Asap
Answers
Answer:
y=−15
Hope this helps! Please mark Brainliest!
Answer:
y = -15
Step-by-step explanation:
5y + 2(11 - 4y) = 82 + y
open parenthesis
5y + 22 - 8y = 82 + y
-3y + 22 = 82 + y
add 3y to both sides of the equation
-3y + 22 + 3y = 82 + y + 3y
22 = 82 + 4y
subtract 82 from both sides of the equation
22 - 82 = 82 + 4y - 82
-60 = 4y
divide both sides by 4
-60/4 = 4y/4
-15 = y
Juan chooses 4 items for his main course, 1 drink, and 1 dessert in a restaurant. The total cost of the meal is $9.80. Each main course item costs $1.10 and the dessert costs 50¢ more than the drink.
Let d represent Juan's dessert and r represent his drink.
Select True or False for each statement
Answers
Answers:
A) TrueB) FalseC) FalseD) TrueE) True===========================================
Explanation:
The two items given
"Juan choses 4 items for his main course""each main course item costs $1.10"tells us that he spends 4*1.10 dollars on just the main course items. So that's why choice A is true.
-----------
From part A, we know that Juan spends 4*1.10 = 4.40 dollars on just the main course items. We also know the total cost of the meal is $9.80
This leaves 9.80 - 4.40 = 5.40 left over
Meaning that $5.40 is spent on dessert and drinks
The equation in part B is close, but the 4.40 should be 5.40 instead.
Choice B is false
-----------
"The dessert costs 50 cents more than the drink" means
r = d+0.50
Whatever the drink costs (d), we add on 50 cents or $0.50 to get the cost of the dessert (r). This is why choice C is false.
-----------
The system of equations we have so far is
[tex]\begin{cases}5.40 = d+r\\r = d+0.50\end{cases}[/tex]
Start with the first equation, plug in r = d+0.50, and solve for d
5.40 = d+r
5.40 = d+d+0.50
5.40 = 2d+0.50
2d+0.50 = 5.40
2d = 5.40-0.50
2d = 4.90
d = 4.90/2
d = 2.45
Each drink costs $2.45, so choice D is true because Juan only bought one drink.
-----------
Lets use this value of d to find r
r = d+0.50
r = 2.45+0.50
r = 2.95
Each dessert costs $2.95, making choice E true as well (since he only bought one dessert).

What is Angles?
When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.
In algebra, two lines can be represented as
a and b are constants in y=ax+ b.
(x,y)
on the Cartesian plane, are points.
Let's say two lines are depicted as
y1 = a1 (x + b1) and y2 = a2 (x + b2)
If and only if, the two lines are parallel.
As any line can be parallel to itself, either b1 is not equal to b2 or b1=b2 and a1=a2.
The characteristic of two simultaneous linear equations that have either no solution or an infinite number of solutions, but not exactly one solution, is another approach to define the term "parallel."
The final definition of the attribute of two lines being "Parallel" states that it is only possible for the X and Y axes to not be parallel to one another. It does not demand for the X and Y axes to be orthogonal to one another or that there be any particular angle between them.
This also applies to the situation of N axes.
Additionally, it is not necessary for Space to be Euclidean or for the 'lines' to be rectilinear.
