There are several information's already given in the question. Based on those information's, the answer can be easily deduced.
The equation given in the question is
x = 0.8x + 72
x - 0.8x = 72
0.2x = 72
x = 360
Now
Number of people that became
member of the site = (80/100) * 360
= 288 people
From the above deduction, it can concluded that the correct option among all the options that are given in the question is 288.
Answer:
.15 dollars per minute.
Step-by-step explanation:
We could do it with algebra. But we can also do it the long way, which is
shorter than the algebraic way.
The digit in the tens place is 3 times the digit in the units place.
So the number MUST be
31, or
62, or
93 .
It can't be anything else.
Now here they are again, with the reverse of each one:
31 . . . 13 The new number is 18 less.
62 . . . 26 The new number is 36 less.
93 . . . 39 The new number is 54 less.
Obviously, the original number is 62.
Answer:
-5 and 6
Step-by-step explanation:
-5 * 6 = -30
-5 + 6 = 1
The equation for the area of a triangle is ½bh or base time height decided by two. So you plug those numbers in: ½18 x 11 = ½198 = 99. The area of the triangle is 99cm².
I hoped this helped
