Answer:
a is less than or equal to 7
Step-by-step explanation:
This is the case because we can treat the less than or equal to sign as an equal sign. The only time it changes is when we divide by a negative, but we do not do that in this problem. First, you subtract 7 from both sides. That leaves us with a 4a on one side and a 28 on the other. Then, you divide both sides by four to get a is less than or equal to 7. I hope this helps!

what is the average hourly pay of someone making $45,000per year. Assuming wage growth of 5% a year, how much would he make the second year
Answers
Answer:
When it’s time for annual performance reviews, if you plan on including pay raises, you need to know the simple math behind calculating pay increases correctly. Raises can be based on any number of things including a worker’s piers, standard industry rates, length of time on the job, the amount of work to do, and even whether or not the boss likes the employee or not. There are few, if any, laws that govern how and when increases are granted, so it’s up to you to determine what you’re willing to give.
Answer:
See belowStep-by-step explanation:
Assume the person works 40 hours a week and 52 weeks a year.
The hourly pay would be:
$45000 ÷ (40*52) = $45000 ÷ 2080 =$21.63The yearly income the second year:
$45000 + 5% = $45000*1.05 = $47250( BRAINLIEST QUEATION)

The price of a dress was reduced from $40 to $30. By what percentage was the price of the dress reduced? STEP BY STEP
Answers
Answer:
The price was reduced by 25%
Step-by-step explanation:
Not sure how to go step by step on this, because it's kinda obvious once you think about it a bit. You need to find what percent of 40 that 10 equals (if that makes sense). So really it's just what percent of 40 equals 10? and since 10 is one fourth of forty, 1/4, then you convert that to percent: 25% (sorry if this made no sense, i'm not very good at explaining things)
