6. L A machine can make 56 parts in 4 hours. It
can also make 70 parts in 5 hours. Write an
equation that relates the number of parts
the machine can make and the time in
hours. Predict how many parts the machine
can make in 9 hours, 30 minutes.

133

Step-by-step explanation:

56/4=14 and 70/5=14. 14 x 9 = 126

30 mins is half of an hour which means you need to divide 14 by 2 which gives you 7.

126 + 7 = 133

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
