Answer:
10, 20
Step-by-step explanation:
x = larger number
y = smaller number
...
x = 10+y
5x=40+6y
...
Substitution of x into the second equation
5(10+y)=40+6y
50 + 5y = 40 + 6y
...
Isolate y
5y - 6y = 40 - 50
-y = -10
Divide both sides by -1
y=10 is the smaller number
...
Rearrange x = 10+y to y = x-10
Substitute into 5x=40+6y
5x = 40 + 6(x-10)
5x = 40 + 6x - 60
...
Isolate x
5x - 6x = 40 - 60
-x = -20
Divide both sides by -1
X=20 is the larger number
2.8 miles.
My Work/Reasoning:
First we find the rate. 7/60 mpm (miles per minutes)
Then we multiply that by 24. 7/60 * 24
Finally, we solve the equation and learn that Chang would run 2.8 miles in 24 minutes.
- ∆ABD is right angled hence area:-
There is only one option containing 6x^2 i.e Option D.
Hence without calculating further
Option D is correct
Answer:
D) 6,191
Step-by-step explanation:
6000 + 100 = 6100
6100 + 90 = 6190
