Combine like terms 7a+4b-3a-2b

Answers

Answer 1

Answer: Combining like terms:

- Could combine numbers that have the same variable
- Numbers with no variable.

7a - 3a = 4a
4b - 2b = 2b

4a + 2b is the final answer

Answer 2

Answer: Like terms...

Well step 1 is to know what a term is. A term, in regards to math, is basically the things between any operation sign (+, -, *, /). Every time you see one of those signs in a problem, you're beginning a new term.
Step 2 is to locate the different terms in this problem. Remember, everything you see up until an operation sign is part of the term. Your term list, for this problem, is:

7a
4b
-3a
-2b

Got it? Cool. Now, we can find the like terms. a like term is a term whose variable and exponents are the same as another like term. Since none of these have exponents, do you see any terms that have matching variables ( which is the letter following the coefficient, which is the number)? Yep! In fact, there are two sets!

First set of like terms: 7a and -3a
Second set of like terms: 4b and -2b

Now that we have our like terms, we have to combine them! Ignore the variable for now... In the first set of like terms, what is 7-3? 4! For the second set, what is 4-2? 2! Since the first set goes with the variable "a", and the second set goes with the variable "b", you should get, as your final answer, 4a + 2b.

What is the maximum value of the cube root parent function on −27 ≤ x ≤ 0?

Answers

Answer:

Step-by-step explanation:

Given an interval -27≤x≤0, to get the cube root of the maximum value, first we need to know the maximum value in the range. The maximum value between -27 and 0 will be 0 which is the greatest value in that interval.

Since the cube root of 0 is 0, the cube root of the maximum value within that range is 0.

The answer should be B.0.

What is 1/4 as a whole number?

Answers

The whole number of $(1)/(4)$ is $\boxed{0.25}.$

Further explanation:

Always use the PEDMAS rule to solve the grouping of multiplication, addition, subtraction and division.

Here, P is parenthesis, E is exponents, M is multiplication, D is division, A is addition and S is subtraction.

Given:

The number is $(1)/(4).$

Explanation:

The whole numbers is the series of numbers that starts from zero.

The natural numbers are those numbers that start from one.

The place values are only natural numbers.

The base ten systems represent the position of a place value.

The given number is $(1)/(4).$

Consider the number $(1)/(4)$ as $\text{A}$ .

$A = (1)/(4)$

Divide 1 by 4 to obtain the whole of $(1)/(4).$

$\begin{aligned}\text{A}&= (1)/(4)\n&= 0.25\n\end{aligned}$

The decimal expansion of $(1)/(4)$ is $0.25.$

The whole number of $(1)/(4)$ is $\boxed{0.25}.$

Answer:

The value of the $(1)/(4)$ as a whole number is 0 .

Step-by-step explanation:

Definition of whole number

A whole number is an integer that is 0 or greater and there are no fractional or decimal numbers .

As given

$= (1)/(4)$

In the decimal form

= 0.25

(As the whole numbers are not express in the decimal form .)

= 0 (Approx)

Therefore the value of the $(1)/(4)$ as a whole number is 0 .

What is the length of a side of a cube with a volume of 729 m3?

Answers

So, You Need To Find The Length Of One Of The Sides. So, Lets Find It Using The Cubed Method. 10*10*10 = 1000, So It Can't Be 10. 5*5*5 = 125, So It Needs To Be Bigger. 7*7*7 = 343, So Bigger. 8*8*8 = 512, So Bigger. 9*9*9 = 729m^3, So, The Side Length Of The Cube Is 9 Meters. I Hope This Helps!
