For the first question, you will write a ratio of 1/2 oz:10 pounds. Please see the attached picture. There are 9 groups of 10 oz in 90 oz, so you will need 9 groups of the amount of medicine too!
For the second question, you need to understand that the exponent (2^3) must be evaluated first because all forms of multiplication/ groupings comes first before adding or subtracting.
Exponents are a way of showing repeated multiplication, so it is done first.
Answer:
A. 3m² + 4m + 1 = 0
3m² + 3m + m + 1 = 0
3m (m + 1) + 1 (m + 1) = 0
( 3m + 1 ) (m + 1) = 0
B. 16n - 25
16n = 25
n = 25/16
Factored form: (x-5)(7x+5) ☺
In getting the x, you must first convert the said data in to a slope intercept form and the formula for it is y = mx+b so the slope is 7/16 while the y is 3.5. In that data its self you can came up with the equation of 3.5 = 7/16x + 0 and the value of X would be 8. I hope you are satisfied with my answer
