Factorisation is basically where you have to find everything in common between 2, 3 or 4 terms.
In factorization, you take out the like-terms. eg.
12x-6y
6(2x-y)
We have to find the HCF of 6 and 12 which is 6.
Here, the 6 is common (goes outside the bracket) and the other numbers (which are in the bracket) are uncommon.
Always remember in factorisation that:
+ and + = –
– and – = +
– and + = –
+ and – = –
Slope intercept: y = mx + b
Subtract 8x
-4y = 20 - 8x
Divide by -4
Y = -5 + 2x
Switch around
Solution: y = 2x - 5
Well, If she takes 15 minutes to pick 135 berries, 30 minutes total would be 270 berries, so if you take another 15 minutes picking berries it would be a total of 405 berries but you still need 81 more. so if she can pick 405 in 45 minutes, it would be around a hour and something.
Hope I helped or at least made you think about it
7.75+1.25x= 32.75
32.75-7.75=25
1.25x= 25
25 divided by 1.25
X= 20
That expression can be written as this:
7x - 6 2/3+ 3x - 4 3/4. When you add like terms:
10x - 11 5/12.
So the answer is:
10x-11 5/12
