If lr = 12 and pr = 4, find lp. explain. lp = 16 because lr + pr = lp according to the segment addition postulate, and 12 + 4 = 16 using substitution. lp = 8 because lp + pr = lr according to the segment addition postulate, and 8 + 4 = 12 using substitution. lp = 16 because 12 + 4 = 16 according to the addition property of equality. lp = 8 because 12 − 4 = 8 according to the subtraction property of equality.

LP = 8 because LR + PR = LP according to the Segment Addition Postulate, and 8 + 4 = 12 using substitution

From this problem, we know that:

LR = 12

PR = 4

So here we have a Line segment. Recall that a line segment has two endpoints, places where they end or stop and they are named after their endpoints, so the line segment here is LR whose measure is 12. Then, according to Segment Addition Postulate it is true that:

LP + PR = LR

By substituting LR = 12 and PR = 4, we have:

LP + 4 = 12

Subtracting 4 from both sides:

LP + 4 - 4 = 12 - 4

LP + 0 = 8

Finally:

LP = 8

B.LP=8 because 12-4=8 according to the subtraction property of equality

Step-by-step explanation:

We are given that if LR=12 and PR=4

We have to find LP

The points L, P and R are collinear points,because they lie on the same line.

When the points are collinear then

LP+PR=LR

We have LR=12 and PR=4

Substituting the values then we get

LP+4=12

LP=12-4

Using subtraction property of equality

Therefore, by simplification we get

LP=8

B. LP=8 because LP+PR=LR according to the segment addition postulates , and 12+4=16 using substitution.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
