Step-by-step explanation:
2(5) + 3(2)=
2x5=10
3x2=6
10+6=16
The value of the expression 2x+3y, when x = 5 and y = 2 is 16.
What are substitution and numerical expression?Substitution in mathematics is when we replace some specific numerical values to variables according to our wants or given in the problem.
A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, we have to find the value of the expression 2x+3y,
when x = 5 and y = 2.
To obtain the value of 2x+3y, when x = 5 and y = 2 we'll substitute 5 in place of x and 2 in place of y.
2x + 3y.
= 2(5) + 3(2).
= 10 + 6.
= 16.

A rental car company charges drivers a flat fee to rent a car plus $0.25 for each mile they drive. If a driver pays
$100 and drives 160 miles, which equation can he use to find his total cost y in terms of the number of miles
driven x? SELECT ALL THAT APPLY
y = 25.2 + 100
y = .25x+ 140
y = .25x + 160
y - 100 = 25(x – 160)
0.25x + 100y = 160
25x – y = 14000
Answer: y-100= 0.25(x-160)
Step-by-step explanation:
Given: Charge per mile = $0.25
Total amount driver pays = $100
Number of miles he drove = 160 miles
Total cost = Flat fee + ( Number of miles he drove) (Charge per mile) ...(i)
i.e. 100= Flat fee + (160)(0.25)
⇒ Flat fee = 100 - (160)(0.25)
If y= total cost , x= number of miles, then
y= ( 100 - (160)(0.25))+ (x)(0.25) [Substitute value of flat fee in (i)]
⇒ y= 100 - (160)(0.25)+ (x)(0.25)
⇒ y-100= (x)(0.25)- (160)(0.25)
⇒ y-100= 0.25(x-160)
Hence, the required equation: y-100= 0.25(x-160)

What is a polynomial?An algebraic equation that has more than two terms, particularly the accumulation of numerous phrases that each include a different power of the same variable (s).
Given, P(x) is a polynomial. Here are a few values of P(x).
P(-6) = 3, P(-4) = -1, P(4) = 2, and P(6) = -5
The remainder theorem says that:
“When a polynomial p(x) is divided by (x−a), the remainder is p(a).
Since, p(6) is -5 and p(-4) is -1
Thus, the remainder when P(x) is divided by (x – 6) is -5
the remainder when P(x) is divided by (x + 4) is -1
Therefore, When Polynomial P(x) is divided by (x -6) and (x +4) the reminders would be -5 and -1 respectively.

1. Evaluate the following numerical expressions. Problem Set a. 2+(-3) +7 b. )-4-1 d. -10 = 2 + 3 C. Ni 2x2 e. (8) + 2 f. 3+(-4)-1 2. Which expressions from Exercise 1 are equal?
Answer:
A equals 12
B equals 3
C equals 3+2+(-5)
E equals 4 NI
F equals -7+(-12)=19
Step-by-step explanation:
For A, you have to do the parenthesis first. I did 2+(-3) which equals -5. Then, I added the 7 to the five and got 12. The reason that it is not 12 is because the +7 is greater than the -5.
For B, I got -3 because -4 - (-1) equals 3. The reason that it is three is because when you look at the positive negative chart, you can see that negative and negative equal positive. So, the answer would be 3.
For E, I got 4 NI because when I multiplied the 2*2 I got 4 then you add the numerals Ni. I am not 100% on this problem, that is kind of my guess.
Finally for F, I got 19. My equation above explains it. Once again, you have to add the parenthesis first, so, -7+(-12) equals 19. Like I said above. If you look at the negative positive chart, the number would be positive because both numbers are negative.
I forgot C above, so here it is. For C, I got the equation above by putting the numbers together. For instance, in the problem on the side, for C, it says -10=3+2. If you just add 3+2, you are going to get 5. I added negative five to it and there you go, you get negative ten.
The first and second problems are equal because 3 goes into 12 equally.

Emily read 24 fiction books and 2 nonfiction books. What is the ratio of the number of fiction books she read to the total number of books that she
read?
Answer:
12:1 or 1:12
Step-by-step explanation:
For every 1 non fiction there is 12 fiction or for every 12 fiction there is 1 non fiction
The required ratio of the number of fiction books she read to the total number of books that she read is 12 / 13.
Given that,
Emily read 24 fiction books and 2 nonfiction books.
To determine the ratio of the number of fiction books she read to the total number of books that she read.
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Number of fiction books = 24
number of nonfiction books = 2
Total number of books = 24 + 2 = 26
The ratio of a fiction book to the total number of books,
= 24 / 26
= 12 / 13
Thus, the required ratio of the number of fiction books she read to the total number of books that she read is 12 / 13.
