Jackson has 1 3/8 of fertilizer he used some to fertilize a flower bed and he had 2/3 kg left how much fertilizer was used in the flower bed

Jackson used 17/24 kg of fertilizers on the flower bed.

To determine the amount of fertilizers that were used in the flower bed = the amount of the fertilizers used – the amount of fertilizers he has left.

= – 2/3, can also be expressed as 11/8,

= 11/8 – 2/3

= (11 x 3) – (8 x 2) / 24 (24 is the smallest number that can divide the denominator)

= (33) – (16) / 24

= 33 – 16 / 24

= 17/24

Therefore, the amount of fertilizers that Jackson used on the flower bed is 17/24 kg

You can solve this type of mathematical problem using BODMAS because the question deals with fractions. If you come across a mixed fraction in any given question, you should convert it to a proper fraction so that it can be easily solved.

Also in case you have to find the lowest common denominator of large numbers, you can multiply the numerators and reduce it if necessary. The smallest number that can divide the denominator is also known as the LCD

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
