Mathematics

stellarik [79]3 years ago

Answer:

x = 4

Step-by-step explanation:

Firstly we have to distribute: 2x + 4x + 6x -2x - 6 = 34

Collect like terms: 10x - 6 = 34

We have to isolate x to get it's value: Add 6 to both sides

10x = 40

Divide both sided by 10: x = 4

Remember to do PEMDAS so your answer is not correct, since you multiplied before doing the parentheses/exponents.

Explanation:
3(3)^2- 5(4)

Articles of clothing that the store received last Thursday is 84

<u>Solution:</u>

Given that  

A clothing donation store received numerous articles of clothing on Thursday of last week.

The number of articles of clothing that the store received last Thursday is represented by the following expression:

4 (3x − 1) − 2 (6 + 2x)

Need to calculate articles of clothing that the store received last Thursday when x = 12.5

As on Thursday x = 12.5, need to substitute x = 12.5 in above equation to get number of articles received on Thursday.

On substituting x = 12.5, we get

4 ( (3 x 12.5 ) – 1 ) – 2 ( 6 + ( 2 x 12.5 ) )

=> 4 (37.5 – 1) – 2 (6 + 25)

=> 146 – 62 = 84

On substituting x = 12.5 , we are getting value of expression as 84.

Hence articles of clothing that the store received last Thursday is 84
