Answer:
See below in Bold.
Step-by-step explanation:
If he scored 76 points he must have answered 76/4 = 19 questions correctly.
If the total number of questions is q then our equation is q = 10 + 76/4
= 10 + 19 = 29 questions.
Answer: Choice D. P = i/rt
This is the same as saying P = i/(rt). The parenthesis are preferred in my opinion to indicate we have rt in the denominator and not just r.
======================================
Explanation:
In the original equation, prt is the same as p*r*t. So we multiply p, r and t to get prt.
This can be thought of as p*(rt). To isolate p, we undo the multiplication done to the variable p. We will divide both sides by rt to get
i = prt
i = p*(rt)
i/(rt) = p*(rt)/(rt) ... dividing both sides by rt
i/(rt) = p
p = i/(rt)
Answer:
divide each term by two and simplify.
