Answer:
They cost 730 all together.
Step-by-step explanation:
One the surface area of the hall is 310m^2.
so, 310 divided by 25 is 12.4, which means they need 13 tin of paint.
The cost for it is 13*10 which is 130.
For the area of the floor, it is 40*15, which is 600m^2.
Which costs 600.
So, 600+130=730.
x - Ram's age now
Ram is half his father's age now, so his father's age is two times Ram's age:
2x - Ram's father age now
x - 10 - Ram's age ten years ago
2x - 10 - Ram's father age ten years ago
ten years ago he was one third his father's age so his father's age was three times Ram's age:
2x - 10 = 3•(x - 10)
2x - 10 = 3x - 30
-10 + 30 = 3x - 2x
20 = x
2x = 2•20 = 40
Answer:
<u>Ram is 20 years old now, Ram's father is 40 years old now.</u>
Answer: 26
Step-by-step explanation: The order of operations says to divided 8 and 2 first, which gives you 4. 18+4=22. Plus 4 again is 26
8x-5=19
+5 on each side
8x=24
Divide by 8 on each side.
X=3
