Is -9.7 rational or irrational give reasoning

1 answer:

4 0

A rational number is any number that can be expressed as a ratio of two integers (hence the name "rational"). For example, 1.5 is rational since it can be written as 3/2, 6/4, 9/6 or another fraction or two integers. Pi (π) is irrational since it cannot be written as a fraction.

A bakery sold a total of 3028 coffee buns and blueberry buns. 1560 more coffee buns were sold than the blueberry buns. How many

Natali [406]

Answer:

$\large{ \tt{ - \: HEY \: AH~\:♡ }}$

$\large{ \tt{✺ \: SOLUTION}} :$

Provided : Total sold bakery items : 3028 coffee buns and blueberry buns & 1560 more coffee buns were sold than the blueberry buns.

To find : Number of coffee buns the bakery sold

- First , Subtract 1560 from 3028 :

$\large{ \tt{→ \: 3028 - 1560 = 1468}}$

We just subtacted the number of more coffee buns from the number of told items sold which means that the number of coffee buns and the number of blueberry buns sold are equal for now. Now divide 1428 by 2 :

$\large{ \tt{→ \frac{1428}{2} = 734 }}$

Now - Let's get back to the second sentence of the question and add 734 & 1560 :

$\large{ \tt{→ \: 734 + 1560 = \large{ \boxed{2294}}}}$

Hence , The bakery sold 2294 coffee buns.

- Hope this helps , oneesan! ;)

Solve this question a=7+3

mr Goodwill [35]

Answer:

Step-by-step explanation:

The answer is 10 because 7 + 3 equals 10!

This can be proven by adding 7 + 3 or by subtracting in a certain way.

7 + 3 = ?

7 + 1 = 8

7 + 2 = 9

7 + 3 = 10

You can show more work by subtracting your answer or 10 in this case, which means that you subtract 7 by 10 or 3 by 10, either way is ok.

If you subtract 7 by 10, ( 10 - 7 ) then you get 3

If you subtract 3 by 10, ( 10 - 3 ) then you get 7

If the number you subtracted matches the number that you didn't subtract, then your answer is correct.

Hope this helps! <3

Answer:

[2] x = -5y - 4

// Plug this in for variable x in equation [1]

[1] 2•(-5y-4) - 5y = 22

[1] - 15y = 30

// Solve equation [1] for the variable y

[1] 15y = - 30

[1] y = - 2

// By now we know this much :

x = -5y-4

y = -2

// Use the y value to solve for x

x = -5(-2)-4 = 6

Solution :

{x,y} = {6,-2}
