Answer:

Correct choice is C

Step-by-step explanation:

Let x be unknown number.

Three times a number x is $3\cdot x=3x.$

Three times a number is no less than negative six means that the number $3x$ can be equal to -6, can be greater than -6, but cannot be less than -6.

Thus, the inequality that could be used to solve the problem is

$3x\ge -6.$

A 13?-foot board is cut into two pieces. The longer piece is 7.5 feet longer than the shorter piece. What is the length of each?

chubhunter [2.5K]

Answer:

The smaller board would be 2.75 feet and the longer one would be 10.25 feet.

Step-by-step explanation:

In order to find this, assume the shorter board is equal to x. Next, we would know that the longer board would be equal to x + 7.5. Using these two assumptions, we can add the lengths together, set equal to 13 and then solve for x.

x + (x + 7.5) = 13

2x + 7.5 = 13

2x = 5.5

x = 2.75

Now that we have the length of the shorter board, we can add 7.5 to it to get the larger one.

2.75 + 7.5 = 10.25

Subtract 9 from both sides.

6x < 54

Divide 6 by both sides.

x < 9

A can of crushed tomatoes holds 40 fluid ounces. How can a label designer name the same volume using metric units? Complete the

inn [45]

The metric unit of a quantity is simply the unit of measurement of the quantity

The volumes of the crashed tomato cans are 1184 milliliters and 1.184 liters

The volume of the crushed tomato can is given as:

$\mathbf{Volume = 40oz}$

From the question, we have the following conversion ratio

$\mathbf{1oz \approx 29.6mL}$

So, the volume in milliliters becomes

$\mathbf{Volume = 40 \times 29.6mL}$

Multiply

$\mathbf{Volume = 1184mL}$

To convert the unit to liters, we simply divide the volume by 1000.

So, we have:

$\mathbf{Volume = 1184L \div 1000}$

$\mathbf{Volume = 1.184L}$

Hence, the equivalent volumes are 1184 milliliters and 1.184 liters
