Answer: 24 and 37
Step-by-step explanation:
Let the numbers be x and y . Also let us pick x as the larger number.
From the first statement :
x + y = 61 ............................ equation 1
From the second statement :
x = y + 13 ............................equation 2
Solving the resulting linear equations by substitution method, substitute x = y + 13 into equation 1, then
x + y = 61 becomes
y + 13 + y = 61
2y + 13 = 61
2y = 48
y = 24
Substitute y = 24 into equation 2 , then
x = y + 3 becomes
x = 24 + 13
x = 37
Therefore the numbers are 24 and 37
Answer:
9 years
Step-by-step explanation:
You want to find t such that y=10.
10 = 7.67(1.03)^t
10/7.67 = 1.03^t . . . . . divide by 7.67
log(10/7.67) = t·log(1.03) . . . . . . take logs
log(10/7.67)/log(1.03) = t ≈ 8.9743 . . . . . years
After about 9 years, the employee will be earning $10 per hour.

Answer:
50
Step-by-step explanation:
25 ----------- 1/2 h (half and hour)
x ------------- 1 h
---------------------------------
25 * 1h = x * 1/2h
25 = x/2
50 = x
he can solve 50 problems in 1 hour
