5+n=10-50

n= -45

Step-by-step explanation:

5+n=10-50

First simplify by solving 10-50:

5+n=-40

Then subtract 5 from both sides:

n=-40-5

Then we have our

n=-45

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
