Answer:
62 newspapers
Step-by-step explanation:
Let s represent the number of Sunday papers sold. Then s/2 is the number of Friday papers sold. The total revenue is ...
1.50s + 0.75(s/2) = 116.25
1.875s = 116.25 . . . . simplify
s = 116.25/1.875 = 62 . . . . . divide by the coefficient of s
62 Sunday papers were sold.
E. 8x+7(325)=15(325)
It would include the 8 hrs. of x miles per hour and the 7 hrs. of 325 miles per hour, giving the total miles. Then, as you eliminate, you can find out what (x) is.
Its the additive identity prosulate
Turn them all into decimals so you can clearly see the difference between them
8 1/9 = 8.11
8.117
8.28
163/20 = 8.15
8 1/9, 8.117, 163/20, 8.28 is your answer
Answer:
x ≈ - 6.74, 0.74
Step-by-step explanation:
x² + 6x - 5 = 0 ( add 5 to both sides )
x² + 6x = 5
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 5 + 9
(x + 3)² = 14 ( take square root of both sides )
x + 3 = ± 
( subtract 3 from both sides )
x = - 3 ±
Then
x = - 3 - ≈ - 6.74 ( to the nearest hundredth )
x = - 3 + ≈ 0.74 ( to the nearest hundredth )
