Answer:x=7
y=2 5/6
Step-by-step explanation:
6(x-5)=12
6x-30=12
6x=12+30
6x=42
6x/6=42/6
x=7
6y-5=12
6y=12+5
6y=17
6y/6=17/6
y=2 5/6
Answer:
rates of change, positive or negative
Step-by-step explanation:
Average weight is when you add up all the weight and divide by the number of objects
if you count the number of x's you will see that you have 10 sandwiches
now add up all the weight
1/8 +1/8+ 1/4+1/4+1/4+1/4+ 3/8+ ....
once you have total weight, divide that number by 10
