4. 5x+6.25
5.2x+40
6.3x+ -6
7. 1x+ 1/5
Answer:
Step-by-step explanation:
a((100+50)/100)(100-50)/100
a(1.5)(.5)=0.75a
So a is larger than a(1.5)(0.5)
How much larger is a than 3a/4?
a/(3a/4)
a(4/3a)
a is 4/3 greater, so it does indicate a 33(1/3)% increase. Maybe they just want the fraction saying it is 1/3 greater or the difference of 0.25a
Answer:
Any letter you want
Step-by-step explanation:
The letters used for variables don't matter. What matters is what the variables represent: their numerical value. Variables are just to help identify what needs solving. Other common variables are a, b, and c which are found frequently in trigonometry. To answer your question, there are no "next letters." You can use any letter you'd like as a variable because it holds the same numerical value. Basically, the whole alphabet is at your disposal.
