Find the values of x and y.

a) x = 20, y = 7
b) x = 10, y = 8
c) x = 50, y = 40
d) x = 10, y = 12

Find The Values Of X And Y.a) X = 20, Y = 7b) X = 10, Y = 8c) X = 50, Y = 40d) X = 10, Y = 12

Answers

Answer 1
4x+5x = 90
9x = 90
x = 10

10y + 10 + 5x = 180
10y + 10 +5(10) = 180
10y + 60 = 180
10y = 120
    y = 12

answer
d) x = 10, y = 12
Answer 2
the answer is the letter D, everytime that you see a square between 2 or more angles means that the adition of all the angles is 90

How to solve a=9y+3yx

Answers

Therefore, the equation [tex]y = \frac{a}{9 + 3x}[/tex] represents y as a function of a and x, showing how changes in a and x affect the value of y.

The given equation a = 9y + 3yx is a literal equation, meaning it relates multiple variables (in this case, a and y) with constants. Our goal is to isolate y, which means we want y to be expressed solely in terms of a and x, without any other variables.

To do this, we first factor out the common factor y from the right side of the equation, leaving us with a = y(9 + 3x). This step simplifies the equation and makes it easier to isolate y.

Then, to solve for y, we divide both sides of the equation by (9 + 3x), effectively undoing the multiplication by (9 + 3x) on the right side. This leaves us with [tex]y = \frac{a}{9 + 3x}[/tex].

In this final expression, y is in terms of a and x, indicating that the value of y depends on the values of a and x. As a and x vary, the value of y changes accordingly, following the relationship described by the equation.

Complete Question:

Solve the literal equation for y.

a = 9y + 3yx

Then, simplify so that x is by itself.

(29.25x2)/13 = x
x= 58.5/13
x=4.5 hours
13/2 = 6.5
They charge $6.50 per hour
29.25/6.50 = 2925/650 = 4.5

2. what can Kevin do to fix it

Answers

Part 1
Kevin did not indicate the conversions between years, days, hours, and minutes.

Part 2
The correct calculation for the number of minutes in 2 years is
[tex]2 \, years \\ = (2 \, years)*(365 \, \frac{days}{year})*(24 \, \frac{hours}{day} )*(60 \, \frac{minutes}{hour} ) \\ = 1,051,200 \, minutes[/tex]

Suppose you used the distributive property to get the expression 12x+3y-9. With what expression could you have started?

Please help.

Answers

the answer could be 3(4x+y-3)
Before using the other methods for factoring, this is the first type of factoring you should try. Basically, you’re reversing the distributive property. What you’re doing is finding the greatest common factor for all of the terms.
Examples:

Factor 2x + 4
Greatest common factor for both of the terms is 2.
2x + 4 = 2(x + 2)

Factor 4x2 + 12
Greatest common factor for both terms is 4.
4x2 + 12 = 4(x2 + 3)

Factor 5x2 + 10x + 25
Greatest common factor for all of the terms is 5.
5x2 + 10x + 25 = 5(x2 + 2x + 5)

Find the greatest common factor for 12, 3 and -9.

After playing with the numbers around, I got 3.

3(4x + y - 3)

So, 3(4x + y - 3) is the answer.

a(n+y)=10y+32 solve for y

Answers

we have

[tex]a(n+y)=10y+32[/tex]

Solve for y

[tex]a(n+y)=10y+32\\an+ay=10y+32[/tex]

Group terms that contain the variable y, and move the other terms to the opposite side of the equation

[tex]ay-10y=32-an\\ y(a-10)=32-an[/tex]

Divide by [tex](a-10)[/tex] both sides

[tex]y=\frac{(32-an)}{(a-10)}[/tex]

therefore

the answer is
