Answer:
x=11 (read below)
Step-by-step explanation:
7 + x = 18
<em>Subtract 7 from both sides</em>
x=11
It's quite simple because if you do something to one side of the equation, you need to do it to the other because otherwise the equation won't be equal. This is how you need to simplify most problems, by taking something from one side and taking from the other as well.
Answer:
Tom was speeding.
Step-by-step explanation:
The driving speed of Tom = 20.3 meters per second.
Speed allowed in the zone = 45 miles per hour zone.
Since the unit of speed allowed is given in miles per hour but the speed of tom is given in meters per second. So, first, we have to convert the meter per second into mile per hour then we can compare and find that Tom is speeding or not.
1 mile = 1609.34 meters
1 hour = 3600 second
Now convert 20.3 into mile per hour.
20.3 meters per second. = (20.3 / 1609.34)*3600 = 45.40981 mile per hour.
Since Tom’s speed is more than the allowed speed so he is speeding.
Answer:
x > -18
Step-by-step explanation:
10 ( x - 9 ) > -270
Treat the inequality like an equation,
Distribute first:
10 ( x - 9 ) > - 270
10x - 90 > -270
Inverse operations:
10x - 90 > -270
+90 +90
10x > -180
/10 /10
x > -18
