Answer:

$\boxed{=144--> C.}$

Step-by-step explanation:

<u><em>You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract that came from left to right.</em></u>

First you calculate with parenthesis first.

$(13-1)^2/2$

$12^2/2$

Then you calculate with exponents.

$12^2=12*12=144$

$144/2$

Next, divide from left to right.

$144/2=72$

$144/72=2$

$72*2=144$

$2*72=144$

$=72$

$2*72$

Finally, multiply from left to right.

$72*2=144$

$12*12=144$

Final answer: $\boxed{=144}$

Please help, solve for x

madreJ [45]

Answer: x=12

First, you do 8 squared = 4(4+x)

Then, you distribute and becomes a two-step equation.

64=16+4x.

So x=12.

An equilateral triangle has perimeter P. The length of one side is P/3. Which expression is equivalent to the length on one side

irina1246 [14]

Answer: $3\times \dfrac{P}{3}=P$

Step-by-step explanation:

Given

The perimeter of one equilateral triangle is P

The lengths of the equilateral triangle are equal

Suppose x is the length of each side

$\therefore 3\times x=P\\\\\Rightarrow x=\dfrac{P}{3}$

i.e.

$\Rightarrow 3\times \dfrac{P}{3}=P$

11. A square-shaped floor is covered with congruent square tiles. If the total number of tiles that lie on the two diagonals is

natita [175]

361 congruent square tiles would be needed to cover the square shaped floor.

<h3>Equation</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Since the number of tiles lying on both diagonals is 37. Let x represent the number of tiles on each side.

Counting one tile twice, there are:

37=2x-1
x=19 tiles on each side.

19² = 361

361 congruent square tiles would be needed to cover the square shaped floor.

Could I get some help?

balandron [24]

Answer:

#adult tickets sold = 346

#student tickets sold = 812

Step-by-step explanation:

let 'x' = # adult tickets sold

let 'y' = # students tickets sold

System of Equations:

x + y = 1158

5x + y = 2542

I used the elimination method and multiplied the first equation by -1

-x - y = -1158

+<u> 5x + y = 2542</u>

4x = 1384

x = 346

346 + y = 1158

y = 812
