Answer:
11th revision
Step-by-step explanation:
The first revision is in 2018, and for each 3 years there is a new revision.
From 2018 to 2048, there are 30 years.
So to find how many revisions there are, we can divide the 30 years by the period of 3 years:
Number of revisions = total period / period per revision = 30 / 3 = 10 revisions.
As the year 2018 also has a revision, we have 10 + 1 = 11 total revisions.
So in 2048 there will be the 11th revision.
Picture 1: The amount of tax for Veena's meal is $1.02
Picture 2: Christian reads 
books per week.
Picture 3: 80% is equal to 
.
Step-by-step explanation:
Picture 1: Veena ate lunch at a deli. She ordered turkey sandwich for $9.25 and a salad for $4.35. The tax was 7.5%. What is the amount of tax for Veena's meal.
Given,
Price of turkey sandwich = $9.25
Price of salad = $4.35
Total amount = 9.25+4.35 = $13.60
Tax = 7.5%
Amount of tax = 7.5% of total cost
Amount of tax = 
Amount of tax = 
The amount of tax for Veena's meal is $1.02
Picture 2: Christian reads 1/4 book every 2/3 week. How many books does Christian read per week?
Given,
Books read every 2/3 weeks = 1/4 books
For determining the number of books read per week, we will multiply both sides by 
Christian reads books per week.
Picture 3: What percent is equivalent to ?
We will multiply the given fraction with hundred for calculating the percentage.
Therefore,
80% is equal to .

Answer:
n=23/10
Step-by-step explanation:
10(n+4)=63
n+4=63/10
n=63/10-4
n=23/10
decimal form: 2.3
She took a total of 60 minutes
she answered both mulitiple choice and extended response in the total time which is 60 minutes
she took 2 minutes on rach multiple choice question and 6 minutes for the extended response
let x=number of multiple choice questions
let y=number of extended response questions
we can deduce that
total time =x*2+y*6
60=2x+6y
also we can deduce
20=x+y
since 20 ia the sum of multiple choice and extended response
for part 2 we just solve the system of equations
60=2x+6y
20=x +y
lets multiply the second equation by 2 so we can get rid of x
60=2x+6y
40=2x+2y
subtracting the two equations from each other to yields
20=0 +4y
y=5
to get x we substitute in one of the equations we derived from question 1
x+y=20
substituting y for its value we get
x+5=20
x=15
