Read the following sentence using mathematical symbols . twice the difference of x and 2, is -22

2(x - 2) = -22

Step-by-step explanation:

* Lets explain how to solve the problem

- There are some words we can change it by mathematics symbols

  like the sum means (+), the difference means (-), the product

  means (×), the quotient means (÷) , one half means 1/2 , triple

  means (×3) and so one

- So we can change any word expression to a mathematical

  expression

* Lets solve the problem

- The sentence is ⇒Twice the difference of X and 2 is -22

- This sentence represents an equation

∵ Twice means Multiply by two

∵ Difference means subtract

∵ is means equal

- Lets explain the parts of the sentence

∵ Twice the difference

- That means we will make the difference at first and then

  multiply the result by 2

∴ Twice the difference of X and 2 means we will subtract 2 from x

and then multiply this difference by 2

∴ Twice the difference of X and 2 represented by 2(x - 2)

∵ Twice the difference of X and 2, is -22 means when we

   subtract 2 from x and multiply the result by 2 the answer

   will be -22

∴ Twice the difference of X and 2 =  -22

∴ 2(x - 2) = -22

* The mathematical symbols of Twice the difference of X and 2,

  is -22 is 2(x - 2) = -22

b.an increase in a causes b to decrease

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
