Answer:
From least to greatest, the correct order is: 
; -7.666....; -7.64; and 
.
Step-by-step explanation:
Since is the only positive number, that means that it will be the greatest number on the list. is equivalent to -7.85, which makes it the smallest number. So you can conclude that the correct order is ; -7.666...; -7.64; and .
So first, you get the absolute value to one side:
Next, set up two equations; One where the value inside the absolute value lines is positive, and another where it is negative, and solve both for the variable:
Your answers are
8 and -8, or +-8.
Answer: Approximately 4.7 hours.
Step-by-step explanation:
He rode the bicycle for some time before it broke down and he walked the remaining distance. This means that Jim covered a total of 165 miles by riding at a speed of 35 miles per hour and walking at a speed of 3 miles per hour.
Let x = the distance covered by riding the bicycle.
Let y = the distance covered by walking.
Time = distance /speed
Time he used in riding would be x/35
Time he used in walking would be y/3
Since the entire trip took 7 hours,
x/35 + y/3 = 7
3x + 35y = 735 - - - - - - - - 1
Total miles covered is 165. Therefore,
x + y = 165 - - - - - - - - -- - -2
Substituting x = 165-y into equation 1, it becomes
3(165-y) + 35y = 735
495-3y + 35y = 735
-3y + 135y = 735-495
132y = 240
y = 240/132
y = 1.81m
x = 165 - 1.81 = 163.19
Amount of time that he spent on the bicycle will be
x/35 = 163.19/35
= 4.66
Approximately 4.7 hours.
Is 1500 ml greater than less than or equal to 1.5 l is equal.
Answer:
2.75
Step-by-step explanation:
let x be the number.
0.75 + 2 = x
2.75 = x
