17. 187 divided by 11 equals 17.
Answer:
Keeping in mind the 'x' is in numerator, i got the answer to be 6.
Step-by-step explanation:
2/7x + 1/2x = 40/7 - 1/6x
2/7x + 1/2x + 1/6x = 40/7
2/7x + (3+1)/6x = 40/7
2/7x + 4/6x = 40/7
2/7x + 2/3x = 40/7
(2*3)+(2*7) / (7*3)x = 40/7
(6+14) / 21x = 40/7
20/21x = 40/7
20x = 40*21/7
20x = 40*3
x = 40*3 /20
x = 2*3
x=6
Answer:
A
Step-by-step explanation:
let the number be x, then
the difference of x and 6 is x - 6 and
5 times the sum of x and 2 is 5(x + 2)
Equate both expressions
5(x + 2) = x - 6 ← distribute left side
5x + 10 = x - 6 ( subtract x from both sides )
4x + 10 = - 6 ( subtract 10 from both sides )
4x = - 16 ( divide both sides by 4 )
x = - 4 → A
