Which temperature is 15°F colder than 45°F?

A) −15°F
B) 25°F
C) 30°F
D) 55°F

(C) 30°F

Step-by-step explanation: Simply add -15 to 45, which gives you 30. -15 + 45 = 30

Its like subtracting 45-15, which equals 30.

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
