2p/9 + 5p/18 - 5/6 = 2/3 + p/12 + 1/6

mezya [45]

$\frac{2p}{9}+\frac{5p}{18}-\frac{5}{6}=\frac{2}{3}+\frac{p}{12}+\frac{1}{6}\ \ \ |Multiply\ by\ 36\\\\
4*2p+2*5p-5*6=12*2+3*p+6*1\\\\
8p+10p-30=24+3p+6\\\\
18p-30=3p+30\ \ \ |Subtract\ 3p\\\\
15p-30=30\ \ \ |Add\ 30\\\\
15p=60\ \ \ |Divide\ by\ 15\\\\
\boxed{p=4}$

My house is 20 miles from yours, but on the map it is only 4 mm away. What is the scale of the map? O A Imm = 5 mi B. I mm = 20

dlinn [17]

$\huge \bf༆ Answer ༄$

Let's use Unitary method to solve the question ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:4 \: mm \rightarrow20 \: miles$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:1 \: mm \rightarrow(20 \div 4) \: miles$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:1 \: mm \rightarrow5 \: miles$

Therefore, 1 mm corresponds to 5 mile according to the map.

so, correct choice is ~

$\overbrace{ \underbrace{\underline{ \boxed{ \sf A }}}}$
