1. Point M is on PQ, PM has a length of 7 units, and point N is the midpoint of MQ. If the length of NQ is 4 units, how long is PQ?
PA
A 3 units
B. 11 units
C. 15 units
D. 18 units

C. 15 units

Step-by-step explanation:

PM = 7 units

pMNQ

   7 unit                     4 unit

NQ = 4 units

Given that

N is midpoint of MQ

it means N divides MQ into two equal parts

thus

MN = NQ = 4 units

now

we have to find length of PQ

pMNQ

   7 unit     4 units     4 unit

PQ = PM + MN + NQ

PQ = 7 units + 4 units + 4 units = 15 units

thus, correct answer is option c 15 units

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

the diver is 33 feet below the surface.
