A student is attempting to solve a multi-step equation. Sample mathematical work is shown below. Which statement best applies to the sample mathematical work?Given the equation -m/2+8=-1/3, I must solve for m. I first subtract 8 from both sides, which gives me -m/2=-25/3 then multiply both sides by –2, which gives me the final answer of m=50/3

Answers

Answer 1

Answer: Although the given statements are missing, the student's step-by-step solution is correct. The student had aimed to isolate the unknown variable in order to solve it. The student made sure the first step was to leave only one term in the side with the variable, before simplifying fractions.

Given data:

Cars Vans Others

60 21 3

The data represents the number of cars on a single day.

Find the relative frequency;

It is the number of times an event occurs.

Here the time frame is within a day;

Relative frequency = $(number of cars + number of vans + others)/(number of days)$

Relative frequency = 60 + 21 + 3 = 84vehicles per day

ii.

Number of vans in a week;

Number vans in a week = 21van per day x 7 days = 147vans

20 yards 8 inches is divided into 26 equal sections, how long is each section

Answers

In the given question, there are several information's of immense importance and worth taking a look. based on these information's, the answer to the question can be easily determined.The length that has to be divided into 26 equal parts is 20 yards and 8 inches.Firstly we have to change the yard into inches and then we can divide the total inches into 26 equal parts.
We know
1 yard = 36 inches
20 yards = 720 inches
Then the total length that has to be divided = (720 + 8) inches
= 728 inches
Now we have to divide the 728 inches into 26 equal parts.
Length of each section = (728/26) inches
= 28 inches.
So each of the 26 parts will have a length of 28 inches.
