Answer:
x=8/7
Step-by-step explanation:
2/3=x/4+x/3
3x/12+4x/12=8/12
7x/12=8/12
x=(8/12)/(7/12)
x=(8/12)(12/7)
x=8/7
Answer: n-4(32.5) > 300;n > 430tep-by-step explanation:
Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is
Profit > $300
the profit he makes is equal to the amount he is paid - the cost of supplies. The cost of supplies is $32.50 for each room. That is
n - 32.5 and
P + 32.5 × 4
Where 4 = number of rooms
P + 130
n-4(32.5) > 300;n > 430tep-by-step explanation:
given that Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is
Profit > $300
Then, the profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is $32.50 for each room. That is
n - 32.5 and
P + 32.5 × 4
Where 4 = number of rooms
P + 130
The minimum profit = 300 + 130 = $430
n-4(32.5) > 300;n > 430 430
Answer:
4
Step-by-step explanation:
8/2 = 4
8/4 = 2
8/0 = 0
8/8 = 1
8/1 = 8
6/144=d/720
d=6*720/144
d=30 defective units
