Answer:
252 bags of maize
Step-by-step explanation:
From the question, we are told that a farmer harvested maize
In the year 2012 = 144 bags of maize
In the year 2013(following year) the harvest decreased in the ratio 3:4
This means
3:4 = 2013: 2012.
Where number of bags harvested in 2013 = unknown = x
3/4 = x/ 144
Cross multiply 4x = 3 × 144
x = 3 × 144/ 4
× = 108
This means 108 bags of maize was harvested in 2013
The total number of bags harvested is = 108 + 144
= 252 bags of maize.
Answer:
3 
Step-by-step explanation:
change 1
to an improper fraction
1
=
, thus
×
=
= 3
or 3.57 ( to 2 dec. places )
2(x + 3) = x - 4
distribute
2x + 6 = x - 4
either subtract 6 from both sides or add 4. i will be subtracting 6.
2x = x - 10
subtract x from both sides
x = -10
Answer:

Step-by-step explanation:
So we have:

This is the same as:

Separate:

Replace the second term with i:

The square root of 66 cannot be simplified.
So, this is our answer :)
