Question

translate the phrase into a mathematical expression and then simplify. Six times a number decreased by four times the same number. Write the corresponding mathematical expression_____
The simplified expression is________

Answer 1

first, give a name (letter) to "a number", then read again the sentence. just this will help.

Answer 2

IM LOST @reemii

Answer 3

for the name of "a number", i choose \(x\).
The sentence becomes: six times "\(x\) decreased by four" times \(x\).
\(x\) decreased by four is \(x-4\). Now continue..

Answer 4

so the answer starts with \(6\times \dots\).
what do you get?

Answer 5

6x-4x

Answer 6

that's right. (i thought the question was "6 times (a number decreased by 4) times the number."
but what you did is better: "6 times a number" - "4 times the same number".
Yes you're right.

Answer 7

so what would be the corresponding mathematical expression? and what would be the simplified expression? @reemii

Answer 8

you wrote 6x-4x. that is the answer to the first question.
simplifying: 2x, isn't it?

Answer 9
