The 30.6 ounce because it would be less money for more as if you bought 3 11.5 once packages trying to spend less you would end up spending more
Answer:
sum=17
Step-by-step explanation:
(a+b)*(a-b)=85
let a=11 and b=6
(11+6)*(11-6)=85
85=85
so the two whole numbers are 11 and 6
and, their sum is : 11+6= 17.
Did you make a mistake because none of these ordered pairs are a solution.
Answer:
The answer is below
Step-by-step explanation:
Let us assume that the age of Greg's brother (Gabe) is x years, and let Greg's age by y years. Since Greg is 10 years older than his brother gabe, then:
y = x + 10 (1)
Also. Greg is 3 times as old as Gabe, hence:
y = 3x (2)
From equation 1 and equation 2:
y = x + 10 = 3x
Hence:
3x = x + 10
Subtracting x from both sides gives:
3x - x = x + 10 - x
2x = 10
Dividing by 2:
2x/2 = 10/2
x = 5 years
y = x + 10 = 5 + 10 = 15 years
Therefore Gabe is 5 years old and Greg is 15 years old
