What's the simplified form of 2x + 3 - x + 5?a. 3x + 8
b. x - 8
c. x - 2
d. x + 8

Answers

D.
Because you can combine all like terms. 2x and -x can be solved. That would equal x. +3 and +5 can be combined to make a positive 8. Therefore the answer would be x+8.

Ok so at first this problem may seem confusing but no worries. MATH is like that so our first step is to combine like terms which are the variables in the equation . So we have 2x+3-x+5 so like I said combine like terms is the first step so 2x and 1x are like terms because they have the variable x involved so when we subtract we get a result of 1x now wr have to add the constants which afr the numbers without variables which would equal the final form 1x+8 your answer is d

Write the phrase as an expression. The difference of a number x and 6.4

Answers

The expression that represents the phrase is x - 6.4

The given parameters are:

Number = x

Value = 6.4

In mathematics, difference means subtraction, and it is represented by the "-" sign

So, the difference of a number x and 6.4 is: x - 6.4

$\huge\mathrm{6.4-x}\checkmark$

$\huge\text{Solution:}$

The difference of two or more numbers simply means we subtract these numbers.

For example, the difference of 10 and 7 is 3.

Now, let's write the difference of x and 6.4 as an expression:

Which is longer ; 180 seconds or 3 minutes?

Answers

Both 180 seconds or 3 minutes are equal.

What is division?

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

We have two times,

180 seconds and 3 minutes.

180 seconds in minutes,

= 180/60

= 3 minutes.

Therefore, both are the same.

Answer:

20 ft² - 4ft² = 16 ft²

Step-by-step explanation:

First we solve for the whole rectangle:

Formula: A = ab

side length a = 5 in

side length b = 4 in

diagonal p = q = 6.4031242374328 in

perimeter P = 18 in

area A = 20 in²

Second we deduct the Area of the cutout of the Square

side length a = 2 ft

Area = a² = 4 ft²

Round this number to two significant figures. 8,468

Answers

Answer:

Rounding to two significant figures the number became

$8468=8\bar{5}00$

Step-by-step explanation:

Given : Number 8,468

To find : Round this number to two significant figure ?

Solution :

Rounding to two significant figure we have to estimate or round the values in terms of zeros.

Rounding the number to hundreds value,

As 6 is greater than 5 so 4 rounds to 5 and rest became zero.

i.e. $8468=8\bar{5}00$

bar means the estimated value.

Therefore, Rounding to two significant figures the number became

$8468=8\bar{5}00$

8500

10^3 x 8.5 = 8500
