Answer:
Step-by-step explanation:
50 can be also written as and the reciprocal means the inverse or to flip the fraction.
I would put the equation into two fractions to make a proportion.
30/24 = 20/x
From there, you'd cross multiply to get:
30x = 480
x = 16
So, if there are 20 children currently in the elevator, 16 adults can still enter.
Given : (5x + 8 - 6x) (4 + 2x - 7)
The given question can be written as : (8 - x) (2x - 3)
⇒ 8(2x - 3) - x(2x - 3)
⇒ 16x - 24 - 2x² + 3x
⇒ -2x² + 19x - 24
<u>Answer</u> : Option D
Answer:
17
Step 1: rerrange the data
8 , 10, 12, 14, 17, 19, 19, 22, 24
Q2 is the median
see that the middle number is 17
282 I believe its a really long answer but to simplify just do the the brackets first so 64. Do all the multiplication next so 8x6 is 48, 4x7 is 28 and 4x64 is 256. Next do addition and subtraction. 48-3+256+9-28
