B. two times the difference of x and seven plus ten
Answer: c= 0.79p
Step-by-step explanation:
Divide each cost by the number of pens it have to find the constant change value.
3.95/5 = 0.79
7.90/10= 0 .79
11.85/15 = 0.79
15.80 / 20 = 0.79
Since the constant change is 0.79 which means that for each pen it will cost you $0.79, then the equation will be c= $0.79p where c is the cost and p is the number of pens.
Answer:
6+8t = 46 t=5
Step-by-step explanation:
Answer:
<h2>d = -4</h2>
Step-by-step explanation:
20 = -d + 16 <em>subtract 16 from both sides</em>
20 - 16 = -d + 16 - 16
4 = -d <em>change the signs</em>
-4 = d ⇒ d = -4
So According to this equation
2x + 5 = -1
=> 2x = -1-5 (As when 5 goes to the right side so it sign changes)
=> 2x = -6
=> x = -6/2 (as when 2 goes to the right side it gets divided)
*Ans = x=-3*
