Answer:

2/6 or 1/3

Each number has 1 /6 probability. But since you can accept either 3 or 4, the probability is better and is 2/6 or simplified to 1/3.

7p + 8p -12 = 59 cans someone help me on this please

notka56 [123]

Combine like terms
7p+8p-12=59
15p-12=59
add 12 to both sides
15p+12-12=59+12
15p+0=71
15p=71
divide both sides by 15
p=4 and 11/15

Find the length of MN

Strike441 [17]

Answer:

The length of MN is 5 cm

Step-by-step explanation:

Add the segment LX, parallel to QP.

Recall the properties of midsegment:

Midsegment is parallel to side,
Midsegment is half the length of the parallel side.

We have:

Since QL = LR, the point L is midpoint of Q,
Since PN = NL, the point N is midpoint of PL,
Since LX is parallel to QP, LX is midsegment of ΔPRQ.

Find the length of LX:

LX = QP/2 = 20/2 = 10 cm

Since QP ║ LX ║ NM, the segment NM is the midsegment of ΔPLX.

Find the length of NM:

NM = LX/2 = 10/2 = 5 cm
