b.5 x -17
c.5 (x + 17)
d. 5+17x

2. Write an equation to represent the statement: "The product of a number and five plus two is equal to 100"
a. 5-x-2=100
b. 5 (x-2)=100
c. 5x + 2=100
d.5-2x=100

3. 5x-1=14
a. x=3
b. x=4
c. x=5
d. x=15

Respuesta :

1) Five times a number = 5x
The sum of 5x and 17 = 5x +17 
A

2) The product of a number and 5 = 5x
5x plus 2 = 5x+2=100
C

3)5x - 1 = 14
5x = 15
x =3
A

1.

The algebraic expression to represent "the sum of 5 times a number and

17" is 5x + 17

2.

The product of a number and five plus two is equal to 100 is represented as

5x +  2 = 100

3.

x = 3

The sum of 5 times a number and 17 is represented as follows:

let

x = the number

Therefore,

5x + 17

The equation that represents the product of a number and five plus two is

equal to 100 is represented as follows:

let

the number = x

Therefore,

5x +  2 = 100

5x - 1 = 14

add 1 to both sides

5x - 1 + 1 = 14 + 1

5x = 15

divide both sides by 5

x = 15 / 5

x = 3
