To solve this problem you must apply the proccedure shown  below:

If , you have that:

Because and

Therefore, as you can see, the answer is:

Answer

9

Explanation

a*b ⇒ 2a + b

2*5 ⇒ ?

Comparing a*b and 2*5, we can say that;

a = 2    and

b = 5

So, substituting a with 2 and b with 5 in the equation 2a + b we have,

a*b   ⇒ 2a + b  

2*5  ⇒ 2(2) + 5

        ⇒ (2×2) + 5

      ⇒ 4 + 5

      ⇒ 9

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
