5^2+4^2=a^2+(-3)^2
25+16=a^2+9
a^2=41-9=32
a=4√2
is answer.
Answer: $26
Step-by-step explanation:
Since the 7 tickets cost $168, the value of each ticket will then be:
= $168/7
= $24
Each ticket cost $24
If one friend gave him $50, the change that the friend will collect will be:
= $50 - $24
= $26
Therefore, Edward should return $26 to the person.
The first answer is correct because the terms are alike in both expressions
Answer: Look at my attached example.
Hopefully this helps with converting units.
Add 2x to both sides,
3x+9=18
Subtract 9 from both sides. 3x=9
Divide both sides by 3.
x=3
