Answer:
14
Step-by-step explanation:
Order of operations rules require that we do any work inside parentheses first. Thus,
–(31 + 2) + 72 – (–5)^2
becomes:
-33 + 72 - 25, or
14
Important: Please use " ^ " to denote exponentiation; (-5)2 is incorrect, whereas (-5)^2 or (-5)² is correct.
3x+2= 32
because if you multiply x by three and then add two to the product, you should get 32.
Answer:90minutes
Step-by-step explanation:
Speed=distance/time
Speed=40miles per hour, distance=60miles
40=60/t
Cross multiply
40t=60
Divide both sides by 40
40t/40=60/40
t=1.5 hour =90minutes
