An algebraic expression that has no like terms and no parentheses is in this form (two Words)

The number of pictures which Karli and her friend can paint in a full hour is equal to 4 pictures.

What is algebra ?

Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.

It is given that Karli and her friend can paint 6/7 of a picture in 3/14 of an hour.

Let's assume they can paint x number of pictures in a full hour.

So , the fraction by dividing 6/7 by 3/14 can be written equal to x .

i.e.,

= x

We need to do the cross product here :

× x =

or

x = () ÷ ()

We know that when dividing two fractions we need to change the division sign to multiplication sign by inverse the fraction value right to the division sign i.e.,

x = () × ()

x = 84 / 21

x = 4

Therefore , the number of pictures which Karli and her friend can paint in a full hour is equal to 4 pictures.

Answer:

4 pictures

Step-by-step explanation:

(6/7)/(3/14)=x/1

cross product

3/14*x=6/7*1

3/14x=6/7

x=(6/7)/(3/14)

x=(6/7)(14/3)

x=(6/1)(2/3)

x=12/3

x=4

Answer:

There exist no rational number between the number 0.4 repeat and 4/9.

Step-by-step explanation:

Consider the provided number.

0.4 repeat and 4/9

This can be written as:

and

Convert the number 4/9 into decimal form.

Here, both the numbers are same so there exist no rational number between the number 0.4 repeat and 4/9.

No, there is no rationalnumber between the number 0.4 repeat and 4/9.

Any number that can be represented as the ratio of two integers and where the denominator is not zero is referred to as rational.

The provided numbers are:

0.4 repeat and 4/9

We can write 0.4 repeat as

Let's convert number 4/9 into decimal:

On dividing 4 by 9 we get 0.444444

Here we see that 4 keeps repeating.

So 4/9 can also be written as

Since, both the given values are same, there can not be existed any rational number between them.

Hence, there is no rational number between 0.4 repeat and 4/9.

Answer:

x = -4 ±√23.

Step-by-step explanation:

x^2 + 8x = 7

(x + 4)^2 - 16 = 7

(x + 4)^2 = 23

x + 4 = ±√23

x = -4 ±√23.

Answer: The correct answer is C.

Step-by-step explanation:

⇒

⇒ which is also,

⇒ So, is a square root of 23.

⇒ Then, it could be positive or negative one:

So that's why the answer would be C.
