Answer:
no solution
Step-by-step explanation:
sqrt(3x+1) +7 = 5
Subtract 7 from each side
sqrt(3x+1) +7 -7= 5-7
sqrt(3x+1) = -2
The sqrt cannot be negative so there is no solution
Equation A simplifies to 0 = 0. It is always true.
Equation B simplifies to 1 = -1 for a ≠ 0. It is never true.
Equation C simplifies to 2a = 0. It is true only for a = 0.
Equation D simplifies to 2a = 0. It is only true for a = 0.
The equation that is true for all values of "a" is ...
A. Equation A
<h3><u>Answer:</u></h3>
<h3>-16 : 8 ✓ </h3>
<h3><u>Solution ( step-by-step ): </u></h3>
The temperature changes -16 degrees ( negative because it wents down ) in 8 hours , So to know the chance per hour, We divide the number of degrees by the number of hours. If we call DT the change of Temperature each hour, we have that:
→ DT = -16 degrees/8 hours = -2 degrees / hour ..

Answer: 360minutes
Step-by-step explanation:
Speed = space/time ; time = space/speed
space = 600km
speed: 100km/h
time = 600km/100km/h = 6hours
Since 1hour = 60minutes
6hours = 6x60minutes = 360 minutes
Answer: 360minutes
