Select all the sums that are positive. A. –5 + (–2)
B. 5 + (–2)
C. –3 + 4
D. 0 + (–3)
E. –2 + 4

The positive sums are:

B. 5 + (–2)

C. –3 + 4

E. –2 + 4

Step-by-step explanation:

We can simply observe the sums to conclude that the sum will be positive or negative.

A. –5 + (–2)

We can see that both numbers are negative, the sum of two nu=egative numbers is also negative.

-5+(-2) = -5-2 = -7

B. 5 + (–2)

The number with greater magnitude is positive so the sum will also be positive.

5 + (–2) = 5-2 = 3

C. –3 + 4

The number with greater magnitude is positive so the sum will also be positive.

-3+4 = 1

D. 0 + (–3)

The number with greater magnitude is negative so the sum will also be negative.

= 0-3 = -3

E. –2 + 4

The number with greater magnitude is positive so the sum will also be positive.

-2+4 = 2

Hence,

The positive sums are:

B. 5 + (–2)

C. –3 + 4

E. –2 + 4

Coefficients are numbers that are multiplied or divided by variables. 10 is a coefficient in this problem, and so is 15. A variable is a letter. c or w are variables. A constant is a number that is not multiplied or divided by anything else. 83.50 is a constant.
