We have 48 meters.
We need to increase it by 20%.
That means we have 48 and then we increase it by 20%.
That can be expressed as:
48 + (48 * 20%)
Now, another way to write that would be:
48 * 120%
Now, 120% is nothing but 120/100. This can even be simplified to 1.2.
48 * 120%
= 48 * 1.2
= 57.6
48m increased by 20% is 57.6m.
so 2 is the remainder of 4
<span> 1/3 (4 - 5x - 1)
= </span><span> 1/3 (3 - 5x)
= 1 - 5/3 x
= - 5/3 x + 1
answer
</span> - 5/3 x + 1
( p.s you put answer choices on a and b the same)
