Answer:

It the 3rd one it's correct cuz i worked it out

Can i have a brainliest please!!:)

Step-by-step explanation:

solve your system by substitution.

c+3d=8;c=4d−6

Rewrite equations:

c=4d−6;c+3d=8

Step: Solve c=4d−6for c:

c=4d−6

Step: Substitute4d−6forcinc+3d=8:

c+3d=8

4d−6+3d=8

7d−6=8(Simplify both sides of the equation)

7d−6+6=8+6(Add 6 to both sides)

7d=14

(Divide both sides by 7)

d=2

Step: Substitute2fordinc=4d−6:

c=4d−6

c=(4)(2)−6

c=2(Simplify both sides of the equation)

Answer:

c=2 and d=2

Divide and write in simplest form.

Answer:

1. $\frac{3}{17}$ (3/17)

2. $\frac{3}{7}$ (3/7)

3. $\frac{45}{184}$ (45/184)

Step-by-step explanation:

1. $\frac{\frac{3}{5} }{3\frac{2}{5}}$ = $\frac{\frac{3}{5} }{\frac{17}{5}}$ = $\frac{\frac{3}{1} }{\frac{17}{1}}$ = $\frac{3}{17}$

2. $\frac{2}{4\frac{2}{3}}$ = $\frac{\frac{2}{1} }{\frac{14}{3}}$ = $\frac{2}{1} /\frac{14}{3}$ = $\frac{2}{1} *\frac{3}{14}$ = $\frac{6}{14}$ = $\frac{3}{7}$

3. $\frac{\frac{5}{4} }{5\frac{1}{9} }$ = $\frac{\frac{5}{4} }{\frac{46}{9}}$ = $\frac{5}{4}/\frac{46}{9}$ = $\frac{5}{2}/\frac{23}{9}$ = $\frac{5}{2}*\frac{9}{23}$ = $\frac{45}{184}$
