Answer:

B. c= -c+2

Step-by-step explanation:

A. ...................

c+2=c+2
c-c= 2-2
0=0

It has infinitely many solutions as the equation is correct for any value of c.

B. ...................

c= -c+2
c+c= 2
2c = 2
c = 2/2
c= 1

It has one solution only

C. ...................

c+2=c-2
c-c= -2 - 2
0 = -4

It has no solution as this equation is incorrect

D. ...................

c-c=2
0 = 2

It has no solution as this equation is incorrect

Daryl's Oreo factory is able to produce 3/4 tons of Oreos in 1 1/2 weeks. At this rate, how long will it take to produce 2

dolphi86 [110]

$\bf \begin{array}{ccll} tons&weeks\\ \cline{1-2}\\ \frac{3}{4}&1\frac{1}{2}\\\\ 2&x \end{array}\implies \cfrac{~~\frac{3}{4}~~}{2}=\cfrac{~~1\frac{1}{2}~~}{x}\implies \cfrac{~~\frac{3}{4}~~}{2}=\cfrac{~~\frac{3}{2}~~}{x}\implies \cfrac{~~\frac{3}{4}~~}{\frac{2}{1}}=\cfrac{~~\frac{3}{2}~~}{\frac{x}{1}} \\\\\\ \cfrac{3}{4}\cdot \cfrac{1}{2}=\cfrac{3}{2}\cdot \cfrac{1}{x}\implies \cfrac{3}{8}=\cfrac{3}{2x}\implies 6x=24\implies x=\cfrac{24}{6}\implies x=4$
