Answers

Answer:

y=x-32

Step-by-step explanation:

y=mx+b where m is the slope and b is the y-intercept.

slope=change in y/change in x

=5/5

y=5x+b --> choose a random point

(7,3) ---> 3=5(7)+b=35+b

b= -32

y=x-32

The correct answer is X = -32

Find the total cost with tip.

Markup (tip $) = percent markup (tip %) x original cost ($)

Total cost = original cost + tip


Mr. Smith goes out to eat for his birthday. The total bill is $122.50. If Mr. Smith leaves a 20% tip, what is the tip amount? What is the total cost of the meal with tip included?

The tip is: $_________

The total cost of the meal is: $_________

Answers

Answer:

$147

Step-by-step explanation:

so to find 20% I usually divide the original cost by 100 to get 1% then multiply that number by 20.

in this case 122.50/100= 1.225, 1.225x20 = 24.5

24.5 + 122.50 = 147

Answers

Answer. 68%
Explanation: divide 17 by 25 and you will get .68 which you convert to a percent

Answer:

68%

Step-by-step explanation:

     Here, it asks for the percentage that attended, and percentage is a ratio expressed as a fraction of 100. First, we must start with the total number of students, not to be confused with the total number of students who attended. The total number of students in the class is 25, which we must multiply to get to a hundred.

     This depends on the number of course. For example, if the number were to be greater than 100, then you would divide, but never adding or subtracting, but in this case, we must stick with multiplying as 25 is less than 100. As you should know, 24 times 4 equals hundred, so you must multiply 17 by 4 too in order for it to be equal, which leaves you with 68/100 attending the part, meaning the percentage of students attending the dance is 68%.

Use the benchmark fraction one half , 1, and 0 to help you estimate each answer before you solve. a one twelve mile b one and five twelfths miles c one and seven twelfths miles d twelve seventeenths mile

Answers

Answer: megan went a total distance of 1 5/12 miles or 17/12 (use which ever you need)

Step-by-step explanation:

Here, we want to calculate the total distance worked around the track

We are told that she ran 9/12 and skipped 8/12

The total distance around the track will be the sum of these two

Mathematically, that will be;

9/12 + 8/12= 17/12 but if wanted in mixed fraction [tex]1\frac{5}{12}[/tex]

Okay so, we want to add both 9/12 and 8/12 which will lead us to 17/12! Now since this is an improper fraction we turn it into a mixed number (if you need to) and the mixed numbers is 1 and 5/12!
