B. Half the speed of the car. and C. The number of different colors on the page.

Variables are symbols for unknown values, so you have to find the statements that contain an unknown value.

A. 27 ⇒ The point value is known, so there is no variable.

B. $\frac{1}{2}$ X ⇒ Since the speed of the car is unknown, the variable X represents the speed of the car. This variable is multiplied by $\frac{1}{2}$ or divided by 2 to get half the speed of the car.

C. X ⇒ The number of different colors is not known, so the variable X represents the number of different colors.

D. 80 ⇒ There is nothing unknown in the statement.

Answer:

1. alternating interior angles

2. 60°

Step-by-step explanation:

1. By definition of <em>Alternating Interior Angles</em>, the angles must be located in between the parallel lines, and opposite of each other (hence alternating). The measurements of the two angles are exactly the same.

2. Since the angle measurements of Alternating Interior Angles are the same, x would = 60° as well.

Talja [164]

Answer:

the number of possibilities that can be drace himself up for the day is 216

Step-by-step explanation:

Given that

jun has 12 t-shirts,6 pairs of pants and 3 pairs of shoes

We need to find out the possibilities that can be drace himself up for the day

So here

$= 12C_1 \times 6C_1 \times 3C_1\\\\= \frac{12!}{1!(12 - 1)!} \times \frac{6!}{1!(6 - 1)!} \times \frac{3!}{1!(3 - 1)!}\\\\= \frac{12!}{1!(11)!} \times \frac{6!}{1!(5)!} \times \frac{3!}{1!(2)!}\\\\= 12 \times 6 \times 3\\\\= 216$

Hence, the number of possibilities that can be drace himself up for the day is 216

The same would be considered and relevant too

Evaluate the expression 4(2x+y)-2y+z for x=-2, y=4 and z=-3

$\blue\textsf{\textbf{\underline{\underline{Answer and How to solve:-}}}}$

Before inserting the values of the variables, I recommend writing the equation in its simplest form.

First, use the distributive property and distribute 4:-

8x+4y-2y+z

Simplifying,

8x+2y+z

Now that the expression is in its simplest form, we can substitute the variables and simplify the expression.

First, write -2 in lieu of x:-

8(-2)+2y+z

-16+2y+z

Now, write 4 in lieu of y:-

-16+2(4)+z

-16+8+z

-8+z

Final step:-

write -3 in lieu of z:-

-8+(-3)

-8-3

-11

C is correct. So it’s asking given any whole number Squared you will get another whole number squared but in reality there are only a few numbers like that and they are called perfect squares(4 16 36 81 121)
