Let Sarah's age be s and Antonio's age be a.
According to your question,
2a + 3s = 34
s = 5a
substituting the value of s in eq. 1,
2a + 3(5a) = 34
= 2a + 15 a = 34
17a = 34
thus, a = 34/17 = 2
substituting the value of a is s,
s = 5(2)
= 10
Thus, Sarah's age is 10 years and Antonio's age is 2 years.
Answer:
12 units
Step-by-step explanation:
We would need to ignore the 3 first of all. We know that 3 is located at the same place. We then need to see 7 and -5. The distance from zero of each numbers matter, not the ammount. So (-5) is 5 from zero. (7) is 7 from zero. 5 + 7 = 12 units
