Answer:B = 18, A = B + 23 = 18+23 = 41.
Step-by-step explanation:Last year . . .
A = 2B + 5 (1)
The number . . .
A = B + 23. (2)
Equations (1) and (2) have the same left sides --- hence, their right sides are equal :
2B + 5 = B + 23.
It implies
2B - B = 23 - 5
B = 18.
ANSWER. B = 18, A = B + 23 = 18+23 = 41.
The experienced window washer can wash all the windows in Mike’s house in 2 hours, which implies that in 1 hour he completes 1/2 of the job.
By the same logic, the new trainee completes 1/7 of the job in one hour.
If they work together, they complete
of the job in one hour, meaning that they complete the job in 14/9 of a hour.
Answer: 10 : 4 : 3
Step-by-step explanation:
According to the question,
For a medicine,
Water used = 1 liter = 1000 ml
Sucrose used = 400 ml
And, Saline used = 300 ml
Thus, the ratio of water, sucrose and saline water for making a medicine,
= 1000 : 400 : 300
= 10 : 4 : 3
Which is the required simplest form of the ratio of water, sucrose and saline water.
