Answer:
X is the same as 14 cm so that means that x = 14 cm
Step-by-step explanation:
Ok so the best way to solve this problem is to simplify it as small as possible so first with the given equation 6(x+7)+3x you need to use the distributive property on 6(x+7)
This should get you 6x + 42
Then you have to add everything with like terms (or everything with the variable x) So add together 6x + 3x and that should get you 9x
So now you are left with
9x + 42 which is C
Hope this helps :D

Answer:
11: 12
Step-by-step explanation:
Let the number of oranges and pears Mr Lynch have initially be x and p respectively.
x -10= ½p
2(x -10)= p
p= 2x -20 -----(1)
Since Mr Lynch did not give any pears away, the number of pears at the end is the initial number of pears.
p= 24
Substitute p= 24 into (1):
2x -20= 24
2x= 24 +20 <em>(</em><em>+</em><em>2</em><em>0</em><em> </em><em>on </em><em>both </em><em>sides</em><em>)</em>
2x= 44
x= 44 ÷2
x= 22


Thus the ratio of orange to pears in the beginning is 11: 12.
