$\frac{26}{52}\cdot\frac{25}{51}\cdot\frac{24}{50}=\\
\frac{1}{2}\cdot\frac{25}{51}\cdot\frac{12}{25}=\\
\frac{12}{102}=\\
\frac{2}{17} \Rightarrow B$

PLS HELP ME ASAP FOR ALL 6!! (MUST SHOW WORK!!!) +LOTS LOTS OF POINTS!!!

Sedaia [141]

1. -4a-6=-12
add 6 to both sides
-4a-6+6=-12+6
-4a=-6
Divide by -4
$a= \frac{6}{4} = 1 \frac{1}{2}$

2. $\frac{3}{5} z- \frac{1}{4} = \frac{17}{20}$
add $\frac{1}{4}$ to both sides but you will need to make a common denominator on the right
$\frac{3}{5} z- \frac{1}{4} + \frac{1}{4} = \frac{17}{20} + \frac{5}{20}$
$\frac{3}{5}z= \frac{11}{10}$
Divide by $\frac{3}{5}$ which means multiply by the <span>reciprocal</span>.
$\frac{3}{5}* \frac{5}{3} z= \frac{11}{10} * \frac{5}{3}$
$z= \frac{55}{30} =1 \frac{5}{6}$

3. $2 \frac{1}{2}(e-1 \frac{3}{4})=5 \frac{1}{2}$
Distribute
$2 \frac{1}{2} e-4 \frac{3}{8} =5 \frac{1}{2}$
Subtract
$2 \frac{1}{2} e=1 \frac{1}{8}$
Divide
$e= \frac{9}{20}$

4. 3w+7=20
Subtract
3w=13
Divide
$w= \frac{13}{3} = 4 \frac{1}{3}$

5. -.2p+.4=-1.2
Subtract
-.2p=-1.6
Divide
p=8

6. $\frac{y}{4} - \frac{3}{5} = \frac{18}{20}$
Add, made sure you change to common denominator first
$\frac{y}{4} = 1 \frac{1}{4}$
Multiply by 4
y=5

Hope that helps
