Six times a number is at least four less than eight times the number. If x represents the number, which will help find the numbe

jeyben [28]

Answer:

The inequation 6x ≥ 8x - 4 can be used to find the solution.

The solution is x ≤ 2

Step-by-step explanation:

If x represents the number then six times a number is the multiplication of x by 6, and four less than eight times the number can be written as: 8x -4

6x ≥ 8x - 4

Solving the inequation;

Subtracting 6x each side:

0 ≥ 8x - 6x -4

Summing 4 each side

4 ≥ 2x

Dividing by 2 each side

2 ≥ x

2 greater or equal than x is the same as:

x ≤ 2

Which one is bigger 30% or 4 /15 ???

Nikolay [14]

I believe 30% is bigger than $\frac{4}{15}$ .

To find the answer, you'd have to convert both the fraction and the percent into decimal form to see which one is truly bigger. Converting the percent is fairly easy. 30% would become 0.30 is decimal form. To find the fraction in decimal form, you'd have to divide the numerator by the denominator, which would be 4 ÷ 15, which makes : 2.6666666666666666666666667.

Now you compare easily. Which one is bigger? 2.666666666666666666666667 or 0.30?

0.30 is bigger. So 30% is bigger out of both of them.
