Firstly we are looking for two variables x,y so that we need two formulas .
the second formula is missing
Answer:
40
Step-by-step explanation:
Answer:
Let Craigs age = x
Therefore Dianes age = 25 + x ( since she's 25 years older)
Dianes + Craigs age = (25 + x) + x = 105 (They said both of their ages sums up to 105)
25 + 2x = 105
2x = 80
x = 40
Craigs age is 40 years old.
Dianes age is 65 years old.
Order of operations
5/8 = 0.625
1/4 = 0.25
0.25*2 = 0.5
0.625-0.5 = 0.125
so the final answer is 0.125
