1 5/6 + 2 1/5
3 + 5/6 + 1/5
3 + 25/30 + 6/30
3 + (25 + 6) / 30
3 + 31/30
3 + 1 1/30
4 1/30
The answer is: 4 1/30 or 4.0333.
Answer:
4 inches per second
Step-by-step explanation:
Speed = distance/time
Given
Distance = 20 feet
12 inches = 1 foot
X inches = 20 feet
X = 20 x 12 = 240 inches
Time = 1 minute = 60 secs
Therefore
Speed = 240/60
= 4 inches per second
Answer:
maybe 90*
Step-by-step explanation:
Change the 30% into a decimal
so its .3
then multiply 2075/.3
and you get $622.50
Original equation
<span>√x+10-9 = -7
</span>Isolate
<span>√x+10 = 9-7
</span>
<span>√x+10 = 2
</span> Raise both sides to the second power
<span> (√x+10)2 = (2)2
</span> After squaring
<span> x+10 = 4
</span>
x + 6 = 0
so the answer is x=-6
