Reduce each ratio to its minimum expression to find if they are equal.
35:28

10:8

Since both ratios reduce to 5:4, they are equivalent.
Another way to check a:b is equivalent to c:d, is that a*d = b*c
In this case, this will be true if 35 times 8 is equal to 10 times 28:

Since both products are equal, then the ratios are equivalent.
Answer:
The base
Step-by-step explanation:
Just did it
We need to now the diameter or radius to find out the circumference.
R times 2 then multiply the product with 3.14
or
D times 3.14
Answer:
just substitute x for 5 and then solve and then substitute x for -1 and solve and subtract the two answers you get
