Answer: 7.3x + 5
Step-by-step explanation:
For us to solve the question, we have to solve 5.2x+8+2.1x-3 and the answer gotten will allow us know the equivalent expression.
= 5.2x+8+2.1x-3
= 5.2x + 2.1x + 8 - 3
= 7.3x + 5
Therefore, the correct answer is 7.3x + 5
Gina shows the steps she took to find the solution of the inequality below.
Describe the error that Gina made and write the correct solution.
19 - 2(1 – x) < 13
19 - 2 + 2x < 13
2x < -4
X > -2
Answer:
hello,2 th made from the wrong place.
because She should have distributed the -2 inside the parentheses.
the process should be like this;
19-2(1-x)<13
17(1-x)<13
17-17x<13
-17x<13-17 (17 goes to the opposite side as -17)
-17x<-4 (we divide each side by 17)
x= -4/-17
I hope you understand. There are errors in the first 2 parts of the question.
What is the value of "twelve more than the quotient of a number and two, decreased by four" when n = 4?
Answer:
10
Step-by-step explanation:
Let
the number = n
The quotient of a number and two = n / 2
twelve more than the quotient of a number and two,
(n/2 + 12)
twelve more than the quotient of a number and two, decreased by four
(n/2 + 12) - 4
when n = 4?
(n/2 + 12) - 4
= (4/2 + 12) - 4
= (2 + 12) - 4
= 14 - 4
= 10

Hey there!
Guide for you do tackle them on your own in the nearer future.
• Percentages are out 100
• The word “of” means MULTIPLY in mathematics
1.)
10% of 40
10% = 10/100
= 10/100 • 40
10/100 = 1/10
1/10 • 40
40/10 = 4
4/1 = 4
Answer: 4 ☑️
2.)
25% of 8
25% = 25/100
= 25/100 • 8
25/100 = 1/4
1/4 • 8
8/4 = 2
2/1 = 2
Answer: 2 ☑️
3.)
20% of 5
20% = 20/100
= 20/100 • 5
20/100 = 1/5
1/5 • 5
5/5 =1
1/1 = 1
Answer: 1 ☑️

At which values of x does the graph of the function F(x) have a vertical asymptote? Check all that apply. F(x)= x-5 / x^2 + 3x -18
Answer:
x=3 , x=-6
Step-by-step explanation:
F(x)= (x-5) / (x² + 3x -18)
vertical asymptote: set denominator to 0 and solve x
x² + 3x -18 = (x+6) (x-3) = 0
x = 3 or x = -6

How is adding and subtracting rational numbers similar and different than adding and subtracting integers?
Answer and explanation:
A rational number is a number that can expressed as fraction where the demoninator of the fraction is not zero, example 2/3, 5/1, 4/6 etc
An integer is a whole number, negative or positive example - 2, 3, -4, 1 etc
Adding and subtracting integers and rational numbers are not very much different. Most numbers are rational numbers anyway. When adding rational numbers 1/2+3/1 for instance, we simply add them like normal fractions:
1/2+3/1= 1+6/2=7/2=2 1/2
When adding intergers 2+4, we add normally as in the number line = 6

A certain city has a population of about 100,000. There are 3,101 people with red hair in the city. Which of these is closest to the probability that a randomly selected person in the city has red hair?
Answer:
3%
hope this helps!
Step-by-step explanation:
The closest probability of a randomly selected person in the city having red hair is approximately 0.03 (or 3%).
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
A certain city has a population of around 100,000 people. In the city, there are 3,101 people with red hair.
The required probability can be calculated by dividing the number of people with red hair by the total population of the city:
= 3,101 / 100,000
= 0.03101,
It can be rounded to 0.03.
Thus, the required probability is 0.03.

There were a total of 480 tickets sold for the school play. Adult tickets sold for $8 and student tickets sold for $5. The ticket sales brought in $3369. How many adult tickets and student tickets were sold?
Step-by-step explanation:
Let A be the number of adult tickets and
let S be the number of student tickets.
From the question we know that
A + S = 480
The revenue from the adult tickets is
A x $8
and the revenue from the student tickets is
S x $5
So the total revenue is
A x $8 + S x $5 = $3369
We can change the first equation to
S = 480 - A
and then plug this into the second equation to get
A x $8 + (480 - A) x $5 = $3369
Simplify the equation to obtain
A = 323
Plug this value into the first equation to obtain
S = 157

Square ABCD is shown below.
If BD = 8x - 50, and DE = 2x + 5, find BE.
A) 15
B) 35
C) 25
D) 45
Answer:
35 is the length of BE
Step-by-step explanation:
2(2x + 5) = 8x - 50
4x + 10 = 8x -50
10+50 = 8x-4x
60= 4x
15 = x
2x + 5 = length of BE equal to length of DE
2(15) +5 = BE
30 +5
35 is the length of BE

Answer:
AB = 2
Step-by-step explanation:
the triangles are similar so that means there is a constant ratio for each side length. so comparing the ratios from the bigger triangle to the smaller triangle, leaves us with 9/3 and 15/5. if you take those and divide them you get 3 for both of them which is the constant. so then in order to find the length of AB just take the side length of XY (6) and divide it by 3 (the constant ratio) and there you have your answer!
hope this helps.

Joe has 0.4 of a black forest cake, which is 14 slices of the cake,left. How many slices of cake were there originally?
Answer:
35 slices originally
Step-by-step explanation:
1. 0.4 means 40%
2. if 14 slives equal 40% we need to divide by 4 to find 10%
3. 14 divided by 4 is 3.5
4. then we multiply 3.5 (10% of the cake) by 10 because 10•10=100(%)
3.5•10 equals 35 slices
