(A) 83 + x
(B) 83 ÷ x
(C) 83x
(C) 83 – x
Answer:
(C) 83x

Explanation:
Product implies multiplication so the product of 83 and x is equal to 83 × x = 83x
Option C.

Question 2.
Which phrase describes the algebraic expression $$\frac{r}{9}$$ ?
(A) the product of r and 9
(B) the quotient of r and 9
(C) 9 less than r
(D) r more than 9
Answer:
(B) the quotient of r and 9

Explanation:
$$\frac{r}{9}$$ is a fraction which implies that r is divided by 9 or the quotient of r and 9
Option B

Question 3.
Rhonda was organizing photos in a photo album. She took 60 photos and divided them evenly among p pages. Which algebraic expression represents the number of photos on each page?
(A) P – 60
(B) 60 – p
(C) $$\frac{p}{60}$$
(D) $$\frac{60}{p}$$
Answer:
(D) $$\frac{60}{p}$$

Explanation:
A total of 60 photos are to be divided equal on p pages imply a problem of division where each page has $$\frac{60}{p}$$ photos.
Option D

Question 4.
Using the algebraic expression 4n + 6, what is the greatest whole-number value of n that will give you a result less than 100?
(A) 22
(B) 23
(C) 24
(D) 25
Answer:
(B) 23

Explanation:
Given expression:
4n + 6
According to the given condition, the inequality becomes:
4n + 6 < 100
Solve for n:
4n < 100 – 6
Or
n < $$\frac{94}{4}$$
Simplify:
n < 23.5
Therefore, for n = 23, the value of the expression will be the greatest and less than 100.
Option B

Question 8.
When traveling in Europe, Bailey converts the temperature given in degrees Celsius to a Fahrenheit temperature by using the expression 9x ÷ 5 + 32, where x is the Celsius temperature. Find the temperature in degrees Fahrenheit when it is 15 °C.

Answer:
Determine the temperature in degrees Fahrenheit
= 9(15) ÷ 5 + 32 substitute for the value of x then multiply
= 135 ÷ 5 + 32 divide 135 by 5
= 27 + 32 add the numbers
= 59 temperature in degrees Fahrenheit
The answer in the grid must be 59.00.
