I am not sure ...but I tried solving it
The answer is 7x-3 if you add like terms which are 4x, 2x, and x then take 2, 3, -2 and subtract from each other
Answer:
2
Step-by-step explanation:
Answer: X = 7√2
Step-by-step explanation:
Let first Consider triangle BDC,
Cos C = adjacent/ hypothenus
Cos C = 7 / x ...... (1)
Also, let consider triangle ABC
Cos C = adjacent / hypothenus
Cos C = x / 14 ....... (2)
Since angle C is the same, equate equation 1 to 2
7/ x = x / 14
Cross multiply
X^2 = 98
Make x the subject of formula
X = sqrt (98)
X = sqrt ( 49 × 2 )
X = sqrt (49) × sqrt (2)
X = 7 sqrt(2)
X = 7√2
Regarding this question it can said that there is nothing special about it. Only thing is converting the word one fifth into the number 1/5 and then multiplying it with the total number of 12000.
One fifth of 12000 = (1/5) * 12000
= 12000/5
= 2400
So 2400 is the one fifth of 12000. Care should be taken while dividing. I hope this is the answer you were looking for and the procedure is perfectly clear to you. In future you can attempt such problems on your own without requiring any kind of outside help. I am glad to have helped you.
