1yard=3 feet
so 3yards would be 9 feet
9*9=81
81/1.5
54 tiles can cover the floor

statuscvo [17]

Answer:

A.there are 3 terms.

B.the variables are x, y, and z.

Step-by-step explanation:

Complete question below:

Consider the following expression and determine which statements are true. x^2+5yz−8

CHOOSE 2 ANSWERS)

A.there are 3 terms.

B.the variables are x, y, and z.

C.The coefficient of x is 2.

D.the term 5yz is made up of 2 factors

The expression x^2+5yz-8

has three terms namely: x^2, 5yz and -8

The variables are x, y and z

The coefficient of x is 1 not 2, so option c is wrong

The term 5yz is made up of more than two factors namely 5, y, z, 5y, 5z, 5yz . So option d is also wrong.

The correct answers are option a and option b

A.there are 3 terms.

B.the variables are x, y, and z

Y and x have a proportional relationship, and y = 12 when x = 8.
OleMash [197]

Answer: x is 12

Step-by-step explanation:

For directly proportional relationship, both variables change in the same direction. It means that an increase in one variable will result to an increase in the other variable. A decrease in one variable will result to a decrease in the other variable.

y and x have a proportional relationship,

We will introduce a proportionality constant and replace the proportionality symbol with an equal to symbol. Thus

y = kx

When y is 12, x is 8

Substituting into the equation,

12 = k × 8

k = 12/8 = 1.5

The equation becomes

y = 1.5x

The value of x when y is 18 will be

18 = 1.5x

x = 18/1.5 = 12
