It is rational, because it can be written as a fraction.
Answer:
e = 7.5
Step-by-step explanation:
Hi,
15 = e/0.5
You need to find what e equals. To do that, you need e all by itself. So to get e by itself in this equation, you need to multiply by 1/2 (same thing as 0.5). 15 x 0.5 is equal to 7.5.
To check your work, 7.5/0.5 is equal to 15.
So you know it's correct.
I hope this helps you :)
9(n+3)=7n-3
1) distribute 9 into (n+3)
9n+27=7n-3
2) subtract 7n on both sides
2n+27=-3
3) subtract 27 on both sides
2n=-30
4) divide by 2
n=-15

Answer:
60
Step-by-step explanation:
The small triangle has a perimeter of 7 inches.
So, since you can fit 3 triangles down the left side of the triangle, you would multiply 7 by 3 to get 21.
Then, since the other side is the same length, multiply 21 by 2 to get 42.
Next, you add 18 to 42 because at the bottom of the picture, it says 18 inches.
That's how you get a perimeter of 60 inches.
