Question

Help me find the answer

Answer 1

I think it would be 20.
H(n-2) times h(n-1)=
H(3-2) times h(3-1)=
H(1) times h(2) which we are told are...
-10(-2)=20

Answer 2

38.5

Explanation:

Lets say, first number = x

Second number = 3x+7

Total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 38.5

Hope this helps!!
