Answer:
8.5
Step-by-step explanation:
This is a simple similar triangles problem
Since 15/7.5 = 2, we know that the ratio between the triangles is 2
This means that 17/x = 2, which means x = 8.5
When you trying to write the decimal value of 4 5/8 then you will get 4+ 5/8. If you know how much 5/8 value in decimal form then you don't need to divide 5 with 8. You just need to convert it separately, make it become 4+0.625 = 4.625.
Since you are skipping a stage it definitely helps and making you write the decimal faster.

Step-by-step explanation:
Observe that 85 is an odd number. That means, one of the prime numbers must be even to have an odd sum with another odd number. As we know, the only even prime number is 2. Hence, the other number is 83.
So, the product of these two prime numbers is 83 x 2 = 166.
Thus, the answer is 166<span>. </span>
