Step-by-step explanation:
option C is correct
as,
4x is a common magnification for scanning objectives and, when combined with the magnification power of a 10x eyepiece lens, a 4x scanning objective lens gives a total magnification of 40x.

You would take 3.5(15) to get $52.50 as your final answer.
Let x = miles traveled by car
Let y = miles traveled by truck.
Because the total distance is 305 miles,
x + y = 305 (1)
Let t = hours of travel by truck. Because the truck speed is 55 mph,
55*t = y
or
t = y/55 (2)
The car has an hour head start, therefore it travels for (t + 1) hours.
Because the car travels at 65 mph,
65*(t + 1) = x
Substitute (2) to obtain
65*(y/55 + 1) = x
or
1.1818y + 65 = x (3)
From (1), obtain
1.1818y + 65 = 305 - y
2.1818y = 240
y = 110
x = 305 - y = 195
From (2),
t = 110/55 = 2 hours
The two vehicles pass each other at 2:00 pm + 2 hours = 4:00 pm
Answer: 4:00 pm
Answer: yes
Step-by-step explanation:
convert 3/4 so the denominator is the same for both fractions. you would just double the fraction : 6/8
now compare 7/8 and 6/8
7/8 is closer to a whole so yes it is greater x
Here are the four solutions:
(3) (x)
(3) (-x)
(-3) (x)
(-3) (-x)
