if a/3=b/2 what are the following ratios? 3a-3b/a-b
Answer:
[tex]\dfrac{3a-3b}{a-b}=\dfrac{3}{1}[/tex]
Step-by-step explanation:
[tex]\text{Given}\\\\\dfrac{a}{3}=\dfrac{b}{2}\qquad|\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup\cdot\dfrac{a}{3\!\!\!\!\diagup}=3\cdot\dfrac{b}{2}\\\\a=\dfrac{3b}{2}[/tex]
[tex]\text{Substitute to}\ \dfrac{3a-3b}{a-b}:\\\\\dfrac{3\cdot\frac{3b}{2}-3b}{\frac{3b}{2}-b}=\left(\dfrac{9b}{2}-3b\right):\left(\dfrac{3b}{2}-\dfrac{2b}{2}\right)=\left(\dfrac{9b}{2}-\dfrac{6b}{2}\right):\left(\dfrac{3b-2b}{2}\right)\\\\=\left(\dfrac{9b-6b}{2}\right):\dfrac{b}{2}=\dfrac{3b\!\!\!\!\diagup}{2\!\!\!\!\diagup}\cdot\dfrac{2\!\!\!\!\diagup}{b\!\!\!\!\diagup}=\dfrac{3}{1}[/tex]
Other method:
[tex]\dfrac{3a-3b}{a-b}=\dfrac{3(a-b)}{a-b}\qquad|\text{cancel}\ (a-b)\\\\=\dfrac{3}{1}[/tex]

Joseph received a $20 gift card for downloading music. Each downloaded song costs $1.29. Explain how to write and solve an inequality that can be used to determine the number of songs that he can purchase. Interpret the solution.
Answer:
So he can buy 15 + he will have on his card left 0.65$
Step-by-step explanation:
20 / 1.29 = 15 song's
20 - 19.39 = 0.65
So he can buy 15 + he will have on his card left 0.65$
the person above me is correct.

(WILL GIVE BRAINLIEST) Solve for x.
-2(-9x+5)-4x=2(x-5)-4
Simplify your answer as much as possible
Answer:
−2(−9x+5)−4x=2(x−5)−4
Step 1: Simplify both sides of the equation.
−2(−9x+5)−4x=2(x−5)−4
(−2)(−9x)+(−2)(5)+−4x=(2)(x)+(2)(−5)+−4(Distribute)
18x+−10+−4x=2x+−10+−4
(18x+−4x)+(−10)=(2x)+(−10+−4)(Combine Like Terms)
14x+−10=2x+−14
14x−10=2x−14
Step 2: Subtract 2x from both sides.
14x−10−2x=2x−14−2x
12x−10=−14
Step 3: Add 10 to both sides.
12x−10+10=−14+10
12x=−4
Step 4: Divide both sides by 12.
12x

Answer:
The distance between the last water shop and the end of the race is 2.1 miles
Step-by-step explanation:
Keep on adding 2.75 until you get the number 11 or you can just multiply 2.75 by 4 and get 11. Subtract 11 from 13.1 and you will get 2.1 miles.

What is the value of the expression
-1s/20r if r= -1/4 and s= 4/5?
Simplify your answer.
Answer:
[tex]\frac{4}{25}[/tex]
Step-by-step explanation:
Given expression:
[tex]-\frac{1s }{20r}[/tex]
r = [tex]-\frac{1}{4}[/tex] , s = [tex]\frac{4}{5}[/tex]
Now;
[tex]-\frac{1s }{20r}[/tex] = [tex]-\frac{s}{20r}[/tex]
Insert the parameters:
= [tex]-\frac{\frac{4}{5} }{20 x (-\frac{1}{4} )}[/tex]
= - [tex]\frac{\frac{4}{5} }{-5}[/tex]
-x - = +
= [tex]\frac{4}{5}[/tex] x [tex]\frac{1}{5}[/tex]
= [tex]\frac{4}{25}[/tex]

Using the substitution of (y=y) what is y= -3x+5 y= -2x+3 (pls help this is)
Answer:
x = 2 and y = -1
Step-by-step explanation:
y = -3x + 5
y = -2x + 3
-3x + 5 = -2x + 3
Add 2x to both sides;
-x + 5 = 3
Subtract 5 from both sides;
-x = -2
Divide both sides by -1
x = 2
Solve for y;
y = -3x + 5
y = -3(2) + 5
y = -6 + 5
y = -1
Find the slope of the line
Y=1/4x + 2

Which of the following
represents a function?
PLEASE HELP 15 POINTS OR BRAINLIEST JUST ASK PLEASE HELP ME
Answer:
A: represents a function
Explanation:
Every other option, A, has two y for one x.
It can be a function if there is 1x for 1y.
If this was helpful, please mark brainliest. Have a beautiful day!
Choice A is not a function because x = 2 leads to more than one y value (y = 1 and y = 7 at the same time)
Choice B is not a function for similar reasoning. Here we have x = 1 lead to y = 2 and y = 5 simultaneously.
Choice D is also not a function because of the two points (5,2) and (5,4). This tells us we have x = 5 lead to y = 2 and y = 4 at the same time.
A function is only possible if you have any input lead to exactly one output. Choice C shows this. Note how it passes the vertical line test. It is impossible to draw a vertical line through more than two points on the function curve.
Help me pleaseeeeee!!!!!
In math formulas, A and a, always represent the same number.
Answer: False
Step-by-step explanation:
In math formulas, we want to use different symbols to represent different things.
While in linguistics, A and a represent the same thing, the symbols are different, then we can use them to represent different things.
For example, we can define a square of side length a.
And the area of that square will be equal to the square of its side length, we can represent the area with A, such that:
A = a^2.
Here A and a are different numbers (and also represent different measures, a is in units of length and A is in units of surface).
Then the statement is false.
