Four friends were born in consecutive years. The sum of their ages is 94. What is the age of the oldest friend?
Savatey [412]
Hello,

We don't need algebra to solve this.

I suppose the ages are 1,2,3,4
Their sum is 1+2+3+4=10.
To obtain 94 we must add 94-10=84 for 4 persons =>84/4=21 to each

Ages are
1+21=22
2+21=23
3+21=24
4+21=25

But if really want an algebric resolution:

Let's x the age of the youngest
x+1,x+2,x+3 the others.

x+(x+1)+(x+2)+(x+3)=94
==>4x+6=94
==>4x=88
==>x=22
Ages are 22,23,24,25.

The oldest friend is 25 years old.

If a car can travel 250 miles on 10 gallons of fuel , how many gallons are requiered to travel 1325 miles
kupik [55]

Answer:

53 gallons of fuel

Step-by-step explanation:

Step 1: Set up a fraction given the data (Let "x" represent the distance in miles.)

\frac{10}{250} = \frac{x}{1325}

Step 2: Divide the given values (The given values are 10 over 250. We are doing this because we need to know the difference between those two figures.) (Trick: For this case, all you need to do is cancel both zeros and the answer is 0.04 once divided)

\frac{10}{250}\\\\10 \div 250\\\\=  0.04

Step 3: Multiply the result to the last value (Since we've found the difference between them by division, we will have to do the <em>opposite operation </em>in order to find the answer.)

1325 \times 0.04\\\\= 53

Therefore, 53 is the amount of gallons of fuel needed.
