Answer:
x = 25
Step-by-step explanation:
x + 25 + 2x - 10 + 90 = 180
3x + 105 = 180
3x = 75
x = 25
3:1 is a common example, or even like 4:3
Answer:
ln(3) + 5 - 3ln(x) or 6.0986 - 3ln(x)
Step-by-step explanation:

=
, since ln(x/y) = ln(x)-ln(y)
= ln(3) +
, since ln(xy) = ln(x) + ln(y)
= ln(3) + 
=
, since ln(
) = yln(x)
= ln(3) + 5 -3ln(x) , since ln(e)=1
if needed further simplification,
ln(3) = 1.0986
ln(e) = 1
= 6.0986 - 3ln(x)
Answer:
D
Step-by-step explanation:
The following options are missing:
A. The value 88 should have been rounded to 8×10²
B. The volume of the shampoo bottle is not 88 in³
C. The volume of the suitcase is not about 10,368 in³
D. The value 10,368 should have been rounded to 1×10^4
Volume of the shampoo bottle: π*radius²
*height = π*2²*7 = 88 in³. Which was rounded to 8×10^1 = 80
Volume of the rectangular prism: length*width*height = 3*2*1 = 6 ft³ or 10368 inches³. Which was rounded to 1×10^5 = 100,000. This is incorrect, it should have been rounded to 1×10^4 = 10,000
