Answer:x=2
Step-by-step explanation:
3(x-2)=6x-12
3x-6=6x-12
Collect like terms
6x-3x=12-6
3x=6
Divide both sides by 3
3x/3=6/3
x=2
Answer:
-5 = -5.4n
Step-by-step explanation:
- 2.4n -3 = -7.8n+2
add 2.4 to both sides

Answer:
Step-by-step explanation:
a) Percentage of potato filling = 100 - (30 + 25) = 100 - 55 = 45 %
b) Let the number of pies sold = x
45% of x = 90
Number of pies = 200
c) Number of cheese filling = 30% of 200
Number of beef pies = 25% of 200
Difference = 60 - 50 = 10
There are 10 more cheese pies than beef pies.
