Answer:
x>-6
Step-by-step explanation:
The expression you need to solve for this is: 2x+15>3
For now pretend that the > is a = and solve as you normally would for x.
Subtract 15 from both sides
2x=-12
Divide by 2
x=-6
Put the > back in
x>-6
Answer:
X = 21/4 - 7/4 = 14/4 = 7/2 = 3 and 1/2
Step-by-step explanation:
X + (2 and 1/2) - 3/4 = 5 and 1/4
X + 2 and 2/4 - 3/4 = 5 and 1/4 <--- common denominator
X + 10/4 - 3/4 = 21/4
X + 7/4 = 21/4
X = 21/4 - 7/4 = 14/4 = 7/2 = 3 and 1/2
Answer:
its 1
Step-by-step explanation:
got it right o the test
Sqrt(49)*sqrt (-1) -4 = 7i-4
We Know, speed = Distance / Time
Here, Distance = 2748 miles
Time = 6 hours
Substitute their values in to the expression,
Speed = 2748 / 6 = 458 Miles / Hour
So, the speed would be: 458 miles/hour
Hope this helps!
