Answer:
Arjun is 20 years old and Shreya is 10 years old.
Step-by-step explanation:
5 YEARS AGO-
Arjun: 2x-5
Shreya: x-5
NOW-
Arjun: 2x
Shreya: x
EQUATION-
2x-5=3(x-5) = 2x-5=3x-15
(add 15 on both sides)
2x+10=3x
(subract 2x from both sides)
x=10
Therefore, Arjun is 20 years old and Shreya is 10 years old :)
Answer:
478
Step-by-step explanation:

102.04/559.45*100
approximately 478
Step-by-step explanation:
192 / 24 = 8

The answer is 8.
Answer:
2.2
Step-by-step explanation:
To find a, you use a formula called the law of cosines:
The law of cosines tells us:
a^2 = b^2 + c^2 - 2bc cosA
So lets plug in the values:
a^2 = 4^2 + 3^2 -2(4)(3)cos(32)
a^2 = 25-24cos32
a^2 is roughly equal to 4.97
therefore a roughly equal to 2.2
Answer:
1/16
Step-by-step explanation:
Since he has a fourth of a pie and he is splitting it into 4 that would make 16 pieces of the whole pie and they are each getting 1/16
