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:
54
Step-by-step explanation:
8(11 - 3) - 2(4 + 1)
11 - 3 = 8
4 + 1 = 5
8(5) - 2(5)
8 * 5 = 64
2 * 5 = 10
64 - 10 = 54
In accordance with Pythagoras theorem ,
7^2 + 13^2 = x^2
49 + 169 = x^2
218 = x^2
√(218) = x
14.764 = x
