It’s times 2 hopefully this helps you got this!!!
X=6 and 2/3
the proportion is also 3:5
Answer:
LK = 7
Step-by-step explanation:
We are using segment addition
NM + ML + LK = NK
x-6 + 9 + 2x-19 = 23
Combine like terms
x+2x -6+9-19 = 23
3x -16 = 23
Add 16 to each side
3x-16+16 = 23+16
3x = 39
Divide each side by 3
3x/3 = 39/3
x = 13
We want to find the value of LK
LK = 2x-19
=2(13) -19
= 26 -19
= 7
Nr of chocolates = c
nr of bags of 5 = a
nr of bags of 7 = b
50<c<70
c=5*a+2
c= 7*b-1 therefore b can be max 10 (if b=11 then c=76>70 can't do)
let's say b=10 then c=69 but in this case a=13.4 not integer (also can't do)
let's say b=9 then c=62 then a = 12 wich is ok
solution 1 c=62
let's also try for b=8 wich means c=55 and a=10.6, not integer, not ok again
and also for b=7 wich means c=48 but 48<50 so no go again and also for b<7 wich means c will grow smaller and smaller
so the only solution is c=62
