Answer:
In arithmetic and algebra, the cube of a number n is its third power, that is, the result of multiplying three instances of n together. The cube is also the number multiplied by its square: n3 = n × n2 = n × n × n.
Step-by-step explanation:
NMQ is 123°. Set it equal to 360° and use congruence
A. Because Belle worked for 35hrs and she earns $12 per hour, which makes $420. Then Belle sold 2550 in cosmetics and 5% in decimals equals 0.05. Multiply 2550 by 0.05 and you get $127.50, that is the 5% commission for the 2550 Belle sold. Lastly add the $420 and $127.50 and you get $547.50 which is answer A.
You would subtract 1/5y, and multiply both sides by 2 (1/2's reciprocal)
For finding difference or sum of unlike fractions ( fractions with different denominators) then we need to make their denominators same ...so for that we take their denominators LCM ...
7/4 - 1/8 (LCM of 4 and 8 is 8)
=> 7/4 X 2 - 1/8
=> 14/8 - 1/8
= 13/8 ..
Hope it helps !!!
