The correct answer is:  [C]:  " -5 ΙxΙ = 25 " .
______________________________________________
In this answer choice, when you divide each side by "-5" ; 

 you get:  " ΙxΙ = -5 ;

If x = 5, the result is "5" ; NOT "-5" .

If x = -5, the result is "5" ; NOT "-5" .

The "absolute value" of a value is always "zero" or greater.

Answer choice:  [C]: has no solution.

A survey found that 78% of students do their homework before 10:00 predict how many students out 975 do their homework before 10
GenaCL600 [577]
Hi Zahra, I've found a very simple and effective way of calculating percentages. 78% refers to 78 out of every 100, which can also be written as "0.78". Now, we can simply multiply 0.78 by your number (975) to get 760.5 students. Obviously, there isn't a half a student, so we round that number up to 761. So 761 out of 975 students do their homework before 10:00.

Given the Arithmetic series A 1 + A 2 + A 3 + A 4 A1+A2+A3+A4 14 + 18 + 22 + 26 + . . . + 86 What is the value of sum?
postnew [5]

Answer:

950

Step-by-step explanation:

The common difference is 4, so the general term can be written:

... an = 14 + 4(n -1)

The value of n for the last term is ...

... 86 = 14 + 4(n -1) . . . . . the computation for the last term, 86

... 72 = 4(n -1) . . . . . . . . . subtract 14

... 18 = n -1 . . . . . . . . . . . divide by 4

... 19 = n . . . . . . . . . . . . . add 1

Your series has 19 terms. The first term is 14 and the last is 86, so the average term is (14+86)/2 = 50. Since there are 19 terms, the sum of them is ...

... 19×50 = 950
