Simipfly (2 3/5) divided by (-3 and 3/4)

Answers

Answer 1

Answer:

-0.533

Step-by-step explanation:

Answer 2

Let's rewrite this question a bit.

[tex]2\frac{3}{5}=\frac{13}{5} \\[/tex]

So, if we want to divide [tex]\frac{3}{5}[/tex] by [tex]-3[/tex], we can write it like this,

[tex]\frac{3}{5} \div -3=\frac{3}{5} \times -\frac{1}{3}= -\frac{1}{5}[/tex]

Now, we are also asked to divide [tex]\frac{3}{5}[/tex] by [tex]\frac{3}{4}[/tex].

[tex]\frac{3}{5} \div \frac{3}{4}=\frac{3}{5} \times \frac{4}{3}= -\frac{4}{5}[/tex]

Hope this helps! :)

A small thing I would like to mention -> In case this wasn't clear or you didn't know, when dividing fractions, we take the reciprocal of the 2nd fraction and then multiply into the first.

So a general formula would look like this:

Let [tex]a,b[/tex] be fractions, then if we want to divide we do,

[tex]a \div b = a \times \frac{1}{b}[/tex]

400 divided by 5. what is the answer

Answers

Answer:

400/5=80

Your answer would be 80

When we divide 400 by 5 we get a quotient of 80.

What are some alternative names for arithmetic operations?

Addition is also known as the sum, subtraction is also known as the difference, multiplication is also known as the product, and division is also known as the factor.

Given, The number 400 is divided by the number 5.

Now, 40 is completely divisible by 5 as 5×8 = 40.

Therefore, 400 divided by 5 would be 80.

We can also write this as N = DQ + R.

#SPJ1

red paint is 1 and blue paint is 3 how much red is there for each blue? Im low on points so u sadly only get 10

Answers

Answer:

1 quart blue + 1 1/2 quart red

Given:

Ratio of blue paint : red paint = 1/3 : 1/2

simplifying this ratio into whole numbers by multiplying both sides by 2 and 3, we get:

(1/3) x (3x2) : (1/2) x (3x2)

2 : 3

From this we can determine the fractions of red and blue paint used in any total purple mix

fraction of blue paint = 2/(2+3) = 2/5 of purple mix

fraction of red paint = 3/(2+3) = 3/5 of purple mix

we are given that we want to make 2 1/2 (= 5/2) quarts of purple paint

hence

amount of blue paint

= fraction of blue paint in purple mix x total amount of purple paint

= (2/5) x (5/2) = 1 quart

amount of red paint

= fraction of redpaint in purple mix x total amount of purple paint

= (3 /5) x (5/2) = 3/2 quart = 1 1/2 quart

Step-by-step explanation:

4.5 liters of red paint

For the temperature one, it is y=7x+42 since it was already 42 degrees and is raising 7 degrees each time. The point-slope one is y-5=7(x+8) since point slope is y-y1=M(x-x1) it gives you the coordinate point and the slope so you just fill it in. For the graph all you need to do is go to -1 on the x axis and draw a line going up and down because that would keep it at -1 but still be a line.

$50 a month

Step-by-step explanation:

X= amount per month

(725-125) /12= x

600/12=x

50=x

Answer:

725= 125+ 12x (equation) 50$ (answer). x (variable)

Step-by-step explanation:

725 = 125+ 12x

-125. -125

600 = 12x

12x = 600

divide 12, both sides

x = 50

So $50 dollars each month.

There's a 12 because there's 12 months in a year and it's asking for "each month"

x is the variable and it stands for how much money $ new members pay each month.
