5a - 10*3 = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15
To be parallel, gradients are the same!
so the gradient is -5/2.
y=-5/2x +c
substitute the points youve been givrn into this to find c!
7=-5/2 (-6) +c
7=15 +c
c must equal -7
y=-5/2x -7
One of the ways to find the answer is to find how much 1 percent of 150 is. To do that we just have to divide 150 by 100:
150 / 100 = 1.5
Now we can divide 9 by 1.5 to know how much percent of 150 it is:
9 / 1.5 = 6
Let's check it:
150 * 6% = 150 * 6/100 = 15 * 6/10 = 3 * 6/2 = 18/2 = 9
It's correct then :)
Answer:
A mile is equal to 5280 feet
You start off with
200 miles per hour
If you multiply 200 by 5280 you can find the speed in feet per hour
1,056,000 feet per hour
There are 60 minutes in an hour
If you divide 1,056,000 by 60 you can find the speed in feet per minute
So 17,600 feet per minute
Then if you divide that by 60 you can find the speed in feet per seconds
It is 293 1/3 or 293.333 feet per second.
Step-by-step explanation:
7s + 20 = 4s -13
7s - 4s = -13 -20
3s = -33
s = -33/3
s = -11
