Answer:
Step-by-step explanation:
3y+2x=30
3y = 30-2x
y=30/3 - 2/3x
y=10-2/3x
now plug in the options
1) 0,10 and 15,0
y=10-2/3*0 where x is 0 and thus y equals y=10-0 --> y =10
For (15,0), y=10-2/3*15 which becomes y=0 so the (15,0) pair works
Which mean line joining 0,10 and 15,0 fits the equation. Now since we want to stay below the $30, area below it is what will get them to stay within budget
Answer:
x < -3
Step-by-step explanation:
This is simply an inequality. This should be fairly easy, but since it has a variable, you need to find the domain. Since -6(1) + 3 = -3, we can't do that. So what can we do? What if we use -1 for x instead? We get 9, so still no. We need to determine when the statement starts becoming true. At this point, -3 for x makes the expression equal to 21. This leads us to our answer.

2. 12 pieces of Candy that need to be separated
Answer:
116
Step-by-step explanation:
82 brownies sold for $1 each is $82 in total
140-82=58
each cookie is sold at $0.5 so we need to multiply the rest of the cash by 2
58×2=116
so he needs to sell 116 more cookies to reach his goal
Answer:
X =1/39
Step-by-step explanation:
1/2+ 6X = 5/6 - 7X Transposing terms
6X + 7X =5/6 - 1/2
13X = 5/6 - 3/6
13X = 2/6 simplifying
13X = 1/3
and transposing 13:
X =1 / (13x3) reducing
X= 1/39
