Divide 275 by 5 which is 55
T = varsta tatalui
f = varsta fiului
anul acesta: t = 4 x f
peste 20 de ani: t+20 = 2 x (f+20)
=> 4 x f +20 = 2 x f + 2 x 20
4 x f - 2 x f = 2 x 20 - 20
2 x f = 20
f = 10
anul acesta fiul are 10 ani
peste 5 ani fiul va avea...
Answer:
The answer to your question is below
Step-by-step explanation:
In Mayan notation there are only 3 symbols
dot . means one
line --- means five
snail means zero
And the are three levels, the lower means x 1
the first means x 20
the second means x 400
the higher means x 8000
Then, 135 is lower than 400, so we must start in the first level and need to divide 135 by 20. 6
20 135
15
Finally place 6 in the fist level and 15 in the lower lever, like this
And 120 + 15 = 135.
Answer:
x = 40
Step-by-step explanation:
In order for m and n to be parallel, the corresponding angles need to be equal. Therefore we get the equation:
3x = 120
Divide both sides by 3 to get:
x = 40
58700 because if you follow the rules of PEMDAS then you would have to exponents 10^4 is 10000 then multiply 5.87 which gives 58700
