Answer:
D
Step-by-step explanation:
I'll try to be brief
Let's plug in our 'y' variable (2x)
2x + (2x) = 20
4x = 20
x = 5
Now, plug in our 'x' variable to get our 'y' variable:
y = 2(5)
y = 10
So, our answer in (5, 10)
Or, D
Answer:
7.41 hours
Step-by-step explanation:
50/5.75 is 7.41.
Answer:
30 m^2.
Step-by-step explanation:
This is a right-angled triangle because it obeys the Pythagoras theorem
( 13^2 = 12^2 + 5^2).
So its area = 1/2 * base * height
= 1/2 * 5 * 12
= 30 m^2
So what even is this make it shorter and I should be able to answer it
