Question

a number multiplied by 8 and divided by four gives 7 more than the number. write an equation of this sentence. thanks

Answer 1

Step-by-step explanation:

To formulate the equation correctly, we must follow the steps given in the exercise.

So the exercise is as follows:

`\begin{gathered} x=a\text{ number} \\ step\text{ 1: (multipl}ied\text{ by 8)} \\ x(8) \\ \text{step 2: }(\text{divided by 4}) \\ (x*8)/(4) \\ \text{step 3:(}result\text{ 7 more than the number)} \\ (x*8)/(4)=7 \\ \text{ANSWER:} \\ the\text{ equation formulated is:} \\ (x(8))/(4)=7 \end{gathered}`

Now to know what the number is, we have to solve the formula formulated.

`\begin{gathered} (x(8))/(4)=7 \\ (8x)/(4)=7 \\ 8x=7(4) \\ 8x=28 \\ x=(28)/(8) \\ x=3.5 \end{gathered}`
