Answer:
x = 9
Step-by-step explanation:
set a proportion: 8/12 = 6/x => 8x = 72 => x = 9
Answer:
the farmer planned to have the work done in 6 days, and the area of the farm field is 120 times 6 = 720 hectares.
(5x)^2 + x^2 = c^2
25x^2 + x^2 =c^2
sqrt 26 x ^ 2 = sqrt c^2
x sqrt 26= c
so answer is 6x + x sqrt 26

Answer:
A = 4, B = 3
Step-by-step explanation:
You require that ...
0.30 × A = 0.40 × B
Then ...
B = (3/4)A . . . . . divide by 0.40
Any pair of numbers that satisfies this equation will be possible values of A and B. One such pair is (A, B) = (4, 3).
