Hi there!!
If you need X to be solved then the answer is X=Y over 5+3 and if your looking for the answer for Y then the answer is Y=5x−15
When you are solving for X you will need to use the distributive property so you can multiply 5 by X-3.
Y=5x-15. Once you've done that then you need to swap sides so all of the variables are on the same side as each other (they need to be on the left side) 5x-15=Y.
Then you need to add 15 to both of the sides to make it look like this ->5x=Y+15
When that's done you then need to divide both sides by 5 so it then looks like this when done.
5x over 5= Y+15 over 5
When you divide this by 5, it then undoes the multiplication by 5.
X= Y+15 over 5
Finally, you need to divide Y+15 by 5
X=Y over 5 plus 3
When solving for Y, all you will need to do is use the distributive property to multiply 5 by X-3.

A toy shop has stuffed Ana I’m als originally priced at $25 each. There is now a 20% discount on the stuffed animals. What is the sale price of each stuffed animal?
Answer:
$20 for each stuffed animal
Step-by-step explanation:
[] The original price is $25, but it is 20% off.
100% - 20% = 80%
[] Now we can find 80% of $25.
-> First, 80% divided by 100 becomes 0.8, a decimal we can work with
25 * 0.8 = 20
Have a nice day!

Tiana is 25 years old. She lives with a roommate and a dog. She has worked at a fancy restaurant for 6 months. She works 40 hours per week and makes $2.13 per hour. She usually serves 45 tables per week. The average bill at the restaurant is $130 per table, and she typically receives a 20% tip. How much does she make in a typical week?
Answer:
$1,255.5 dollars per week
Step-by-step explanation:
40Hr * $2.13 = $85.2 per week from hours alone
$130 * 0.20 = $26 tip per table
$26 * 45 tables = $1,170 in tips
$85.2 + $1,170 = $1,255.2 per typical week

Is (4,2) a solution to this system of equations?
y = -x + 6
y = 2x - 4
Answer:
No
Step-by-step explanation:
substitute the x- coordinate of the point into both equations and if the value obtained is equal to the y- coordinate then the point is a solution.
y = - 4 + 6 = 2 ← true
y = 2(4) - 4 = 8 - 4 = 4 ≠ 2 ← false
Thus the point is not a solution to the system
Seventy percent of what number is 35?
Seventy percent of fifty (50) is 35
What is the percentage?The percent or percentage of a number is the division of the number with 100.
From the given information, we are being told that 70% of a number is 35.
Let's assume that the unknown number is: (x)It means that:
70% of x = 35
[tex]\mathbf{(\dfrac{70}{100})x = 35}[/tex]
0.7x = 35
Divide both sides by 0.7
x = 35/0.7
x = 50

A mathematics test has 15 items. In how many ways can a student answer the exam with 9 correct answers and 6 wrong answers?
a. 15
b. 30
c. 90
d. 5,005
Answer:
Surprisingly the answer is 5,005.
Basically this is asking "in how many ways can you choose 9 things from a set of 15 things".
You will need to use the formula found at the top of this page:
https://www.1728.org/combinat.htm
Filling in the formula in which 'r' = 9 and n = '15'
combinations = n! / (r! * (n-r))!
combinations = 15*14*13*12*11*10 * 9! / (9! * 6!)
combinations = 15*14*13*12*11*10 / 6*5*4*3*2*1
combinations = 14 * 13 * 11 * 10 / 4
= 14 * 13 * 11 * 2.5
= 5,005

How many workers should be added to complete the work in 16 days ?Solution :-
According to the question ,
→ In 20days 12 workers can do a piece of work.
→ In 1day 12*20 workers can do that work
( Less days , more workers )
→ In 16 days 12*20/16 = 15 workers can do the work.
So 15 -12 = 3 workers should be added to complete the work.

// Solve equation [2] for the variable x
[2] x = 2y + 4
// Plug this in for variable x in equation [1]
[1] (2y+4) - y = 1
[1] y = -3
// Solve equation [1] for the variable y
[1] y = - 3
// By now we know this much :
x = 2y+4
y = -3
// Use the y value to solve for x
x = 2(-3)+4 = -2

Answer:
Step-by-step explanation:
a) y = -1/4x --------------(I)
x + 2y = 4 -----------------(II)
Substitute y = (-1/4)x in equation (I)
[tex]x + 2*\dfrac{-1}{4}x=4\\\\\\x -\dfrac{1}{2}x=4\\\\Multiply \ the \ entire \ equation \ by \ 2 \\\\2x -x = 8\\\\x=8[/tex]
[tex]Substitute \ x = 8 \ in \ equation \ (I)\\\\y=\dfrac{-1}{4}*8\\\\\\y = -2[/tex]
Answer: x = 8 ; y = -2
b) y = -x - 2 --------------(i)
3x + 3y = 6 -----------(ii)
Divide equation (ii) by m
x + y = 2
y = -x + 2 ----(iii)
From (i) and (iii), it shows that these lines have same slope. So, they are parallel lines
Answer: No solution
3) -8x + 2y =4
2y = 8x + 4
Divide the entire equation by 2
y = 4x + 2 -------------(i)
y = 4x + 2 ----------------(ii)
From (i) and (ii), we come to know that these lines coincide.So, they have infinite solutions.

Signs of trig functions:
Answer:
Step-by-step explanation:
Each one of the trig functions is plus in two quadrants.
The sin(theta) is plus in 2
The Tan(theta) is plus in 3
The cos(theta) is plus in 4
Rule: if the trig function is not plus, then it is minus.
So if Tan (theta) is minus it means theta is in quad 2 or quad 4
So in this case theta is either in quad 2 or quad 4.
The sin is plus, that means that theta is in quad 2.

Answer: the top right
Step-by-step explanation:
What is the domain of the function y = StartRoot x 6 EndRoot minus 7?.
A function is a mapping from domain to range. The domain of the function [tex]y = \sqrt{x+6} - 7[/tex] is given as: [tex]x \geq -6[/tex] or [tex]x \in [-6, \infty)[/tex] (both are same)
What is domain and range of a function?Domain is the set of values for which the given function is defined.Range is the set of all values which the given function can output.One method of finding the domain of a function is to start by finding the values for which it isn't defined.
Assuming that the function [tex]y = \sqrt{x+6} - 7[/tex] is defined for only real numbers, then, as we know that:
[tex]\sqrt{x}[/tex] exists only if x is non-negative, which means for [tex]\sqrt{x+6}[/tex] to be defined, we need
[tex]x + 6 \geq 0\\x \geq -6[/tex]
No other way is there for the function to be non-existing.
Thus, the values on which the function is defined is all real numbers bigger or equal to -6. This is the domain of the given function.
Thus, the domain of the function [tex]y = \sqrt{x+6} - 7[/tex] is given as: [tex]x \geq -6[/tex] or [tex]x \in [-6, \infty)[/tex] (both are same)

an employee earns $31.20 after four hours and $54.60 after seven hours. What is the employees hourly rate of pay?
Answer:
$7.80 an hour
Step-by-step explanation:
$31.20/4 = 7.8
$54.60/7 = 7.8
Answer:
$7.80 per hour
Step-by-step explanation:
I know this equation might seem a bit complicated, but it's actually really simple. Just divide.
$31.20/4 = $7.80
Now we just have to make sure the second one matches.
$54.60/7 = $7.80
Since they both match, the hourly rate of pay is $7.80.
