Answer:

Solving the inequality 3x -2 < 4 we get \mathbf{x

Option D is correct option.

Step-by-step explanation:

We need to solve the inequality 3x -2 < 4 and find value of x

Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.

3x -2 < 4

Adding 2 on both sides

3x -2+2 < 4+2\\3x < 6

Now, we will divide 3 on both sides

\frac{3x}{3}

So, we get x < 2

Solving the inequality 3x -2 < 4 we get \mathbf{x

Option D is correct option.

You first need to know how much miles it takes on the trail. Then you look 20 x 3 is one hour. And if the 3 group said it takes 2 hours waking for them its like this, the first group takes one hour to go thru the trail, but the second group takes and hour and half the 3 group takes 2 hours.

I wish this helps. :)

The ratio of Dawn to Mandy's savings is 6 : 7. The ratio of Mandy to Belle's savings is 2 : 3. Find the ratio of Dawn to Belle's
Mila [183]

The savings are illustrations of ratio, and the ratio of Dawn to Belle's savings in the simplest ratio is 4 : 7

<h3>How to determine the ratio?</h3>

The given ratios are:

Dawn : Mandy = 6 : 7

Mandy : Belle = 2 : 3

Multiply the second ratio by 3.5.

So, we have:

Mandy : Belle = 2 * 3.5 : 3 * 3.5

Evaluate

Mandy : Belle = 7 : 10.5

So, we have:

Dawn : Mandy = 6 : 7

Mandy : Belle = 7 : 10.5

Mandy's ratios in both equation are the same.

So, we have:

Dawn : Mandy : Belle = 6 : 7 : 10.5

Remove Mandy's ratio

Dawn : Belle = 6 : 10.5

Simplify

Dawn : Belle = 4 : 7

Hence, the ratio of Dawn to Belle's savings is 4 : 7
