The steps are to first distribute the 1/3 into (x-9) and then to move the +6 on the left over to the right:
First distribute:
y + 6 = 1/3(x-9) becomes y + 6 = 1/3x-3
Now subtract 6 from both sides:
y = 1/3 x - 3 - 6
y = 1/3 x - 9
Answer:
(1,-1)
Step-by-step explanation:
y = -1
5x+7y = -2
Substitute the first equation into the second
5x + 7(-1) =-2
5x -7 = -2
Add 7 to each side
5x-7+7 = -2+7
5x= 5
Divide by 5
5x/5 = 5/5
x =1
(1,-1)
Answer:
<u>We need to buy 3 cases of juice.</u>
Correct statement and question:
No. of diners = 240 Portions of juice served = 4 oz. per diner Size of juice can = 48 oz. How many cases of juice required if there are 8 cans in a case and you must buy a whole case?
Source:
Previous question that you can search at brainly
Step-by-step explanation:
Let's calculate the number of cases of juice are required this way:
Number of cases required = [(Number of dinners * portion of juice served)/Size of juice can]/Cans in a case
Replacing with the real values, we have:
Number of cases required = [(240 * 4)/48]/8
Number of cases required = [(960)/48]/8
Number of cases required = 20/8
Number of cases required = 2.5
<u>But let's remember that we must buy only whole cases, then we need to buy 3 cases of juice.</u>
