The temperature at 8: 00 a. m. was −6 degrees f and the temperature at 3: 00 p. m. was 11 degrees f. the equation −6 + c = 11 can be used to find c, the change in temperature. use the inverse property of addition to solve the equation. show your work.

c = 17

Step-by-step explanation:

Add 6 to both sides, obtaining c = 6+ 11  =  17.  So, c = 17.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
