1 answer:
RSB [31]3 years ago
5 0

Answer:

x - 2y = 32

Step-by-step explanation:

Start with y + 7 = (1/2)(x - 18).

Clear out the fractions by mult. both sides by 2:

2y + 14 = x - 18

Subtract 2y + 14 from both sides, obtaining:

0 = x - 2y - 14 - 18, or

0 = x - 2y - 32

Then x - 2y = 32.  This is in standard form.

How do you do this? Please help
PtichkaEL [24]

Answer:

PO=86.2\\ OM=23.8\\

Step-by-step explanation:

To preface, your figure is going to be a line segment, with O as your midpoint, in between points P & M.

With that being said:

PO+OM=PM

Identify your values:

PO=7y+12\\OM=3y-8\\PM=110

Substitute the values into the first equation:

7y+12+3y-8=110

Combine like terms:

10y+4=110

Subtract 4 from both sides of the equation:

10y=106

Divide by the coefficient of y, which is 10:

y=10.6

Substitute 10.6 for y in segments PO & OM:

PO=7(10.6)+12

OM=3(10.6)-8

PO=74.2+12

OM=31.8-8

Solve:

PO=86.2

OM=23.8

Check your answers by substituting:

PO+OM=PM

86.2+23.8=110
