7x/2+ 5 = 8
subtract 5 from each side
7x/2 =3
multiply by 2 on each side
7x = 6
divide by 7
x = 6/7
The value of x would be equal to 6/7.
WE know that equation is an expression that shows the relationship between two or more numbers and variables and mathematical equation is a statement with two equal sides and an equal sign in between.
We are given the equation as;
7x/2+ 5 = 8
Now subtract 5 from each side
7x/2 =3
To multiply by 2 on each side
7x = 6
Then divide by 7
x = 6/7
The solution will be 6/7.

reflection, across the x-axis,
for the point (-8,-7)?
Answer: (8,-7)
Step-by-step explanation: Since you are reflecting over the x-axis, the x coordinate stays the same, but the y coordinate does change. Instead of it being negative, the eight would become positive.
Answer:it’s -7,-1 and -7,1
Step-by-step explanation:
13(19 – x)
Answer:
7/39 = 17.94%
Step-by-step explanation:
Town Students Relative Frequency
Wilmette 12 boys + 7 girls = 19 19/39 = 48.72%
Glencoe 9 girls + 4 boys = 13 13/39 = 33.33%
Kenilworth 2 boys + 5 girls = 7 7/39 = 17.94%
Total 39 students 39/39 = 100%
Another approach to solve probability is the Relative Frequency. A frequency is the number of times an event occurs. To solve for the relative frequency, it’s the ratio of the frequency of an event to the total outcomes. From the question, it is clear that for each town, it was subdivided into boys and girls but the word students represent the combined number of boys and girls for a particular town. so finding the probability that a student called at random to answer a question is from kenilworth is simply the ratio of students from kenilworth over the total number of students in the class.
