8/7
Step-by-step explanation:
1. flip the numbers
2.loo

Server to cook ratio is 5 : 2......added = 7
this means that 5/7 of the cooks and servers are servers and 2/7 of the cooks and servers are cooks
so if the total cooks and servers is 42..
5/7 * 42 = 210/7 = 30 of them are servers <===
2/7 * 42 = 84/7 = 12 of them are cooks
Answer:
x = 2
Step-by-step explanation:
5(2x-6) +20 =10
Open up the brackets.
10x - 30 +20 =10
10x - 10 =10
Add 10 to both sides.
10x - 10 (+10) = 10 (+10)
10x = 20
Divide both sides by 10
10x/10 = 20/10
x = 2
