A 12-pound bag weighs more than a 200-ounce bag. True or false?
Question 9 options:
True
False

Answers

Answer:

False. A 200-ounce bag would weigh more than a 12-pound bag.

Hope this helps!

The statement "A 12-pound bag weighs more than a 200-ounce bag." is True.

What is Unit Conversion?

The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.

Given:

A 12-pound bag weighs more than a 200-ounce bag.

As, we know

1 pound = 16 ounce

So, the weight of bag in ounces

=12 pound

= 12 x 16

= 192 ounce

So, the statement is True.

Answers

Answer:

well your right the answer is -8

Step-by-step explanation:

here's what you should do

1) Simplify both sides of the equation.

3+4(x−3)=5−2(−3x−1)

3+(4)(x)+(4)(−3)=5+(−2)(−3x)+(−2)(−1)(Distribute)

3+4x+−12=5+6x+2

(4x)+(3+−12)=(6x)+(5+2)(Combine Like Terms)

4x+−9=6x+7

4x−9=6x+7

2) Subtract 6x from both sides.

4x−9−6x=6x+7−6x

−2x−9=7

3) Add 9 to both sides.

−2x−9+9=7+9

−2x=16

4)  Divide both sides by -2.
