Step-by-step explanation:
Let Jack's present age be x
Hence, his fathers present age=4x
Jacks age after 5 years= (x+5)
Jacks Fathers age after 5 years= (4x+5)
We know.. that the difference between their ages fives years later is 10.. hence
4x+5-(x+5)=10
4x+5-x-5=10
3x = 10
x= 3.3 years old...
Hence,
Jacks present age = 3.3 years
Fathers present age= 13.2 years...
Hope it helps .. I know that the answer comes in decimals... but the questions' like that..
The value of a is 8 and b is 2
Answer:
20. Which of the following is the correct first step to solve 5x2 – 20x = -15 by completing the square?
O Divide all terms by 5. this is the answer
O Divide all terms by -5.
Add 15 to both sides.
Add 100 to both sides.

Step-by-step explanation:
Answer:
Work out the Area of the figure, then multiply that answer by $25.
(60 times 4 ) plus (25 times 2)
60•4=240 in^
25•2=50in^
Surface of it all is
240 in^ + 50 in^ = 290 in ^
