Answer:
Its the 2nd one
Step-by-step explanation:
Simplify the exponents and then multiply
The difference between the highest and lowest temperature is 85°F.
The answer is -1/16 or -0.0625, do you need to see work?
(1/7) Multiplied By x is 1/7x And (1/7) Multplied By Positive 21 is 3. So It Will Then Change To 1/7x + 3 = -6.
Subtract 3 From Both Sides. Then The Equation Changes To 1/7x = -9
Then Since (1/7) Basically Means To Divide You Would Multiply By 7 On Both Sides And Then x Would Equal -63!(:
Then Can Plug In -63 Where x Is To Check Your Work! Hope I Helped!
