If the answer is D. the equation to represent the ages of students is:
n + n+1 + n+2 = 45
it is showing that n is the age of one student and the other student has age one year more than the first one and third students has age of 2 years more than first student and one year greater than the second student. if we solve this equation for the value of n, we get;
3n + 3 = 45
3n = 45 -3
3n = 42
n = 14
so the age of one student is 14, second student 15 and third student 16 years.
and if we add there ages, 14 + 15 + 16 = 45
Answer:
8
Step-by-step explanation:
6(6)-20-32(1/4)
36-20-8
16-8

Okay so 3/25 (OF) 140 you'd have to do 140 divided by 25 then times that answer by 3. 140 divided by 25 = 5.6. 5.6 x 3 = 16.8. You can't have 16.8 people so you round it which makes it 17 people.
Answer:
0.80
Step-by-step explanation:
The garden area is 120 ft^2 and the yard area 150 ft^2.
The probability that a single seed will land in the garden is thus:
120 ft^2
------------ = 4/5 = 0.80
150 ft^2
