Answer:
<em>Isolate the variable by subtracting 7 from all 3 parts of the inequality, and then dividing each part by 2. To solve inequalities like a < x < b, use the addition and multiplication properties of inequality to solve the inequality for x.</em>

Answer:
11 cups of dough
Step-by-step explanation:
1 cup x 11 dumplings = 11 cups of dough needed
Joel = j, Mark = m, Sandra = s
j + m + s = 120
m = 3j
j = 1/2 s --> s = 2j
plug in (substitute) each letter to make it in terms of only j: j + m + s = 120
j + 3j + 2j = 120
6j = 120
6j/6 = 120/6
j = 20
now plug in for the j & s equation:
s = 2j = 2(20) = 40
Therefore Sandra has 40 coins!
We can do this by using either long division or synthetic. I will use synthetic because it saves time. 6x^3-37x^2+32^x+15.
Perpendicular:
(50-1)/6-6= slope=undefined= vertical line
y-17=0(x-14)
y-17=0
y=17
Parallel:
since line 1 is vertical we need another vertical line in order for them to be parallel so the line is x=- 4
