Answer:
x : y = 5 : 2
Step-by-step explanation:
Given
[tex]\frac{x+3y}{5x+4y}[/tex] = [tex]\frac{1}{3}[/tex] ( cross- multiply )
5x + 4y = 3(x + 3y)
5x + 4y = 3x + 9y ( subtract 3x from both sides )
2x + 4y = 9y ( subtract 4y from both sides )
2x = 5y ( divide both sides by 2 )
x = [tex]\frac{5}{2}[/tex] y ( divide both sides by y )
[tex]\frac{x}{y}[/tex] = [tex]\frac{5}{2}[/tex] , that is
x : y = 5 : 2
Answer:
x/y = 5/2
Step-by-step explanation:
hello :
(x+3y) /( 5x+4y)= 1/3 means : 5x+4y = 3(x+3y)
5x+4y = 3x+9y
5x-3x = 9y - 4y
2x = 5y
now divid by y : 2x/y = 5y/y
2x/y = 5 so : x/y = 5/2

What is the vertex of f(x) = |x + 8| – 3?
(-8,-3)
(-8,3)
(8,-3)
(8,3)
The vertex of the function f(x) = |x + 8| - 3 is (-8, -3).
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given is an absolute value function,
f(x) = |x + 8| – 3
For a function of the form,
f(X) = a |x - h| + k, the vertex of the function is the point (h, k).
Comparing the equation with the given one,
f(x) = |x + 8| – 3
f(x) = |x - (-8)| + (-3)
So we get, h = -8 and k = -3.
So vertex is (-8, -3).
Hence the vertex is (-8, -3).

The drama club sells tickets to their spring play. They sell 180 tickets for a
total of $2,248. Adult tickets cost $14 each. Student tickets cost $10 each.
How many adult tickets and how many student tickets do they sell?
Show your work.
The number of adult and student tickets are 112 and 68 respectively
How to determine the number of adult and student tickets?Word problems are sentences describing a 'real-life' situation where a problem needs to be solved by way of a mathematical calculation.
Set up equations to represent the problem.
Let the A and S represent the numbers of adult and student ticket respectively. So we can write:
A + S = 180 --- (1)
14A + 10S = 2248 --- (2)
From (1):
A = 180 - S ----(3)
Put (3) in (2):
14A + 10S = 2248
14(180 - S) + 10S = 2248
2520 - 14S + 10S = 2248
2520 - 4S = 2248
4S = 2520 - 2248
4S = 272
S = 272/4
S = 68
Put S = 68 in (3):
A = 180 - S
A = 180 - 68
A = 112

If y varies directly as z and inversely as x and y = –18 and z = 3 when x = 6, find y when x = 5 and z = –5.
36
18
9
64
Answer:
y = 36
Step-by-step explanation:
Given y varies directly as z and inversely as x then the equation relating them is
y = [tex]\frac{kz}{x}[/tex] ← k is the constant of variation
To find k use the condition y = - 18, z = 3 when x = 6 , then
- 18 = [tex]\frac{3k}{6}[/tex] ( multiply both sides by 6 )
- 108 = 3k ( divide both sides by 3 )
- 36 = k
y = [tex]\frac{-36z}{x}[/tex] ← equation of variation
When x = 5 and z = - 5, then
y = [tex]\frac{-36(-5)}{5}[/tex] = [tex]\frac{180}{5}[/tex] = 36

what is 10 x 567 divded by 2 x 45
Answer:
63
Step-by-step explanation:
Answer: 63
Step-by-step explanation: First, you would do 10 x 567.
10 x 500 = 5000
10 x 60 = 600
10 x 7 = 70
5000 + 600 + 70 = 5670
Next, you find out 2 x 45.
2 x 45 is equivalent to 45 + 45.
45 + 45 = 90
Finally, you divide the product by the product - 5670 divided by 90.
The answer to that is 63.
