Answer:
40
Step-by-step explanation:
52= 1/2(64 + x)
52 = 32 + 0.5x
52-32= 32-32 + .5x
20=.5x
Divide both sides by .5x
X = 40.
Answer:
544 miles
Step-by-step explanation:
this problem is a multiplication problem, if one inch is 32 mile, and San Antonio to El Paso is 17 inches you have to multiply 17 and 32 to get 544 miles
Step 1. Apply FOIL method. bb+b*2+8b+8*2
Step 2. bb+2b+8b+8*2
Step 3. Add similar elements. bb+10b+8*2
Step 4. Apply exponent rule. b^2+10b+8*2
Step 5. Multiply the numbers. b^2+10b+16
b^2+10b+16 is your answer.
The second person must be 20 years old, since that is the median of the ages.
If the mean is 22 years, then the sum when all three added together is 66.
That means, the youngest and the oldest add up to 46 years old.
Let the oldest be x + 16, then the youngest must be x.
x + 16 + x = 46
2x + 16 = 46
2x = 30
x = 15
Since the youngest person is 15, the oldest must be 31.
Hence, the ages, from youngest to oldest, are: 15, 20, 31
