Answer:
9/12
Step-by-step explanation:
3/4 times 3 = 9/12
3/4 is equivalent to 9/12 so those would be the two anwsers
Answer:
to a function is increasing we have to find the slope of the function
the higher the slope the faster the growth
Step-by-step explanation:
- slope = 5/2. which is 2.5
- slope 2 = -1/2 which is -0.5
- slope 3 = 3/2 which is 1.5
- slope 4 = 1/2 which is 0.5
- slope 5= 4/3 which is 1.33
- slope 6 = 3/4 which is 0.75
so the function in increasing order
y= -1/2x + 1/2
y= 1/2x - 2
y=3/4x - 10
y=4/3x -7/3
y=3/2x-11/2
y=5/2x +10
In order to solve this we need to make on part of both statements equal.
Since 12 is divisible by 6 lets do that.
Multiply everything in the second package by 2.
It then becomes 6 pairs for $12.
So now have have 6 or 8 pairs for $12.
You are getting a different amount for the same price therefore they are not proportional.
16 is the answer. I think
Answer: the rate of speed for train A is 66 miles per hour.
Step-by-step explanation:
Let x represent the speed of train B.
2 trains leave the station at the same time. Train A is traveling 16 miles per hour slower than train B. This means that the speed of train A would be x - 16 miles per hour.
The two trains are 720 miles apart after 4 hours. It means that both trains traveled a total distance of 720 miles in 4 hours.
Distance = speed × time
Distance travelled by train A after 4 hours is
4(x - 16) = 4x - 64
Distance travelled by train B after 4 hours is
4 × x = 4x
Since the total distance travelled by both trains is 720 miles, then
4x - 64 + 4x = 720
8x = 720 - 64 = 656
x = 656/8 = 82 miles per hour
The speed of train A would be
82 - 16 = 66 miles per hour.
