Alex has a box of pens and pencils. Of all his pens and pencils,
drek231 [11]

Answer:

a. p = n + m

where: n is the number of pens, and m is the number of pencils

b. p = 71

Step-by-step explanation:

Let the number of pens  and pencils that Alex has be represented by n and m respectively.

But,

number of pens, n = 14

number of pencils, m = 57

Then,

total number of pens and pencils, p = number of pens + number of pencils

i.e p = n + m

p = 14 + 57

p = 71

The total number of pens and pencils that Alex has is 71.

From a mountain side 418 meters above sea level, Jess took off in his helicopter and descended 88 meters before climbing 120 met
Igoryamba

He started at 418 above sea level. descended means he moved down so subtract 88 from 418:

418 - 88 = 330 feet.

He then climbed 120, so now add that to the 330:

330 + 120 = 450


He is now at 450 feet above sea level.
