Answer:
The answer is B.
Step-by-step explanation:
r- (-12.4) = -15.8
r + 12.4 = -15.8
-12.4 -12.4
r = -28.2

It would still be 7:2 because when tripled, you triple both numbers, so you get 21: 6, which is the same thing as 7:2, but you just use more. And for ratios, they usually want them to be in simplest form, so it is d) 7:2. The ratio does not change when you triple both sides.
The sequence is by "multiply by 2"
Answer:
length is 7.5 and width is 4.5
Step-by-step explanation:
Its given that perimeter of the triangle is 24 units.
The condition is that length is 3 units more than the width.
l=w+3;
Formula for perimeter is 2(l+w).
so ,
2(w+w+3)=24,
2w+3=12,
w=4.5,
l=w+3=7.5
Hence for the given conditions length is 7.5 and width is 4.5.
