Answer:

-6

Step-by-step explanation:

1. Treat the problem like a subtraction problem because -2.5 + (-3.5) can be rewritten as -2.5-3.5

2. When adding or subtracting negative numbers, keep these rules in mind:

Same signs add and keep.

Different signs subtract.

Keep the sign of the higher number.

-2.5 -3.5 have the same sign, so add them up and keep the sign.

And you do get -6.

-9 + p/2= -13 <br> (two step equations, show your work)

malfutka [58]

Answer:

p=−8

Step-by-step explanation:

Regroup terms.

p /2 −9=−13

Add 9 to both sides.

p/2 =−13+9

Simplify -13+9 to −4.

p/2=−4

Multiply both sides by 2.

p=−4×2

Simplify 4×2 to 8
