how do i solve Solve 4/9=x/45.

Answers

You multiply 45 on both sides and get x=20

Answer:

x = 20

Step-by-step explanation:

I would say that there are two ways to solve this.

First way:

You could simply this equation be cross multiplying.

4/9 = x/45 → 180 = 9x

Next, divide 180 by 9.

20 = x → x = 20

Second way:

Considering that fraction bars mean division, you could cancel out x/45 by multiplying both fractions by 45.

4/9 = x/45 → 20 = x → x = 20

Answers

Answer:

A is the correct answer

Step-by-step explanation:

Because the dot on -1 means -1,2 and the dot on -5 means -5,2 I hope this helps

The number line can be used to find the distance between (–1, 2) and (–5, 2) is of option A; A number line going from negative 7 to positive 3 in increments of 1. Points are at negative 5 and negative 1.

What is a number line?

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.

Given;

we have number line that can be used to find the distance between (–1, 2) and (–5, 2)

The y-coordinates of the points are the same, therefore the distance between those points will be the difference of the x-coordinates. The first number line shows those x-coordinates plotted properly which can be used can be used to find the difference between them.

Therefore the correct answer is option A

There are 2 mixtures of light purple paint. Mixture A is made with 5 cups of purple paint and 2 cups of white paint. Mixture B is made with 15 cups of purple paint and 8 cups of white paint. Which mixture is a lighter shade of purple? Explain your reasoning. *

Answers

Answer:

Mixture B

Step-by-step explanation:

The mixture with more white paint would have a lighter shade of purple.

Mixture A is 2/7 white paint while Mixture B is 8/23 white paint.

2/7 is approximately 0.286

8/23 is approximately 0.348

0.348 > 0.286 so Mixture B is made of more white paint than Mixture A and therefore is a lighter shade of purple.

Answer:

mixture B :D

not mixture A

The Taco Hut sells 2 tacos for $2.18, 3 tacos for 3.00, 4 tacos for 3.82, 5 taocs for 4.64. if this patern goes on, how much wound 8 tacos.

Answers

Answer: $7.10

(2,2.18) (3,3) (4,3.82) (5,4.64)

First find the rate of change using y1-y2/x1-x2

3-2.18/ 3-2

=0.82

Next, find the y-intercept or the flat rate

Use the formula y-y1=m(x-x1)

y-3=0.82(x-3)

y-3=0.82x-2.46

y=0.82x+0.54

Next, replace x with 8 for 8 tacos

y=0.82(8)+0.54

y=7.1

Answers

Answer:

Step-by-step explanation:

Answer:

X (Blank) = 15

Step-by-step explanation:

To get started: You must subtitude the blank with X/variables, to get solving.

23+15=x+23

Step 1: Simplify both sides of the equation.

23+15=x+23

(23+15)=x+23(Combine Like Terms)

38=x+23

Step 2: Flip the equation.

x+23=38

Step 3: Subtract 23 from both sides.

x+23−23=38−23

x=15 (Final answer)

4.) Write the equation of the line shown below? SHOW WORK!

Answers

Answer: y=1/5x-3/5

Explanation:

Use points (3,0) and (-1,-1) to find the slope and y-intercept.

Use y1-y2/x1-x2 to find slope

-1-0/-1-4
=-1/-5
=1/5

So the slope is 1/5

Then use y-y1=m(x-x1) to find the y-intercept.

y-0=1/5(x-3)

y-0=1/5x-3/5

So the equation is y=1/5x-3/5

Choose the correct set of y-values for the function y = -2x when x = -2, 0, 2.

What is a function?

"A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B. A relation f from a set A (the domain of the function) to another set B (the co-domain of the function) is called a function in math. f = {(a, b)| for all a ∈ A, b ∈ B}

A relation is said to be a function if every element of set A has one and only one image in set B.

Here, the given function is y = - 2x.

When the value of 'x' is - 2, the value of 'y' is

= - 2(- 2) = 4.

When the value of 'x' is - 2, the value of 'y' is

= - 2(0) = 0.

When the value of 'x' is 2, the value of 'y' is

= - 2(2) = - 4.

Therefore, the set of values of for the given function are (- 2, 4), (0, 0), (2, -4).
