Using Imperial Measurements
Answer:
Square your height in inches. For example if you are 70 inches tall, then multiply 70 by 70. The answer would be 4,900.
Divide weight by height. If you weigh 180 pounds, then divide 180 by 4,900. The answer is 0.03673.
Multiply your last answer by 703. This equals 25.82 so your BMI in this example would be 25.8.
The equation is simply (height^2), (weight/height^2), (Answer*703) = BMI.

Answer:
9/22
Step-by-step explanation:
First:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
−9/4 ÷ −11/2
Applying the fractions formula for division,
=−9×2 divided by 4×−11
=−18/−44
Simplifying -18/-44, the answer is
=9/22
Your answer would be 1, or 72+25.
What is happening in this case is a negative number is being subtracted from a positive. This means you are taking away a negative. The two negatives cancel each other out, and then it becomes you are adding a positive.
Another way I like to think about this is the two minus symbols combine together to form a plus sign.
Hope this helped!
-5y + 8 = -3y + 10
We need to get y on one side.
Add 3y to both sides.
-2y + 8 = 10
We need to get 2y by itself.
Subtract 8 from both sides.
-2y = 2
Divide both sides by -2 to solve for y.
y = -1
I hope this helps!
