Answer:Corey was travelling at 9 miles per hour and Tom was travelling at 13 miles per hour.
Step-by-step explanation:
Let x represent Corey's speed.
If Tom travels 4 mph faster than Corey, it means that Tom's speed would be (x + 4) mph
Corey is 176 miles from Tom and they are traveling towards each other. If they meet after 8 hours, it means that they travelled a total distance of 176 miles in 8 hours.
Distance = speed × time
Distance travelled by Corey in 8 hours would be
8 × x = 8x miles
Distance travelled by Tom in 8 hours would be
8(x + 4) = (8x + 32) miles
Since the total distance travelled by Tom and Corey is 176 miles, then
8x + 8x + 32 = 176
16x = 176 - 32 = 144
x = 144/16 = 9 miles per hour
Tom's speed would be
9 + 4 = 13 miles per hour
The coordinate would be (-3,4) so the answer is 4
It is important to do the
calculations very carefully. Otherwise there is nothing complicated about this
problem.
Let us assume the unknown number = x
Then
40x/100 = 55
40x = 55 * 100
40x = 5500
x = 5500/40
= 550/4
= 137.5
So
55 is 40% of 137.50. I hope the procedure is clear to you and in future
you can solve such problems on your own without requiring any help from
outside.This is the simplest way of solving such
problems.
Answer: (2,<u>-5</u>)
Step-by-step explanation:
The slope of the line formed by this set of number is 2 (y increases by 2 for every 1 increase in x). The line has the form y = 2x + b. Enter one of the data points to find b.
y = 2x + b for (2,3)
3 = 2*2 + b
b = -1
The equation is y = 2x - 1
The missing value: y =2*(-2) - 1
y = -5
(2,-5)
7 is the same thing as 7/1
we can multiply 7/1 by 5/5
which is 35/5
There are 35 fifths in 7
Hope it helps
