Answer:

Kristen bought 2 fancy shirts and 5 plain t-shirts.

Step-by-step explanation:

Given that,

Kristen spent $131 on 7 shirts.

Cost of one fancy shirt = $28

Cost of one plain t-shirt = $15

Let,

x be the number of fancy shirts

y be the number of plain t-shirts

x+y = 7       Eqn 1

28x+15y=131    Eqn 2

Multiplying Eqn 1 by 15

15(x+y=7)

15x+15y=105    Eqn 3

Subtracting Eqn 3 from Eqn 2

(28x+15y)-(15x+15y)=131-105

28x+15y-15x+15y=26

13x=26

Dividing both sides by 13

[tex]\frac{13x}{13}=\frac{26}{13}\\x=2[/tex]

Putting x=2 in Eqn 1

2+y=7

y=7-2

y=5

Hence,

Kristen bought 2 fancy shirts and 5 plain t-shirts.

Answer:

3 / 4r

Step-by-step explanation:

Simplify : 7r/ 2 ÷ 14r²/3

7r/ 2 ÷ 14r²/3

Changing the ÷ sign to multiplication :

Multiply 7r/2 by the reciprocal of the denominator :

7r/ 2 * 3/14r²

((7 * r) / 2) * (3) / 14 * r * r

= 3 / 4r

Answer:

18x - 36

Step-by-step explanation:

In an equilateral triangle the 3 sides are congruent, then

perimeter = 6x - 12 + 6x - 12 + 6x - 12 ← collect like terms

                = 18x - 36

The required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

As we know in an equilateral triangle the 3 sides are congruent.

The perimeter of the triangle = 6x - 12 + 6x - 12 + 6x - 12

Combine the likewise terms and we get

The perimeter of the triangle =  18x - 36

Therefore, the required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

Answer:

The robot can clean the room without recharging.

Step-by-step explanation:

Given:

After a robot vacuum is fully charged, it can run for [tex]15[/tex] minutes.

The robot cleans [tex]\frac{1}{2}[/tex] square foot every second.

To find: If the charged robot can clean a room that is [tex]400[/tex] square feet without recharging.

Solution:

Area cleaned by the robot in [tex]1[/tex] second [tex]=\frac{1}{2}[/tex] square foot.

We know that, [tex]1[/tex] minute [tex]=60[/tex] seconds.

So, [tex]15[/tex] minutes [tex]=15\times 60=900[/tex] seconds.

Now, area cleaned by the robot in [tex]900[/tex] seconds [tex]=\frac{1}{2} \times 900=450[/tex] square feet.

The area to be cleaned is [tex]400[/tex] square feet.

Hence, the robot can clean the room without recharging.

Answer:

68

Step-by-step explanation:

The formula for finding the are of a right triangle is

A= 1/2bh

( area = base times height divided by 2)

17 is the base and 8 is the height, 8*17=136

136÷2=68

The unit rate of the snail's movement is 3 inches per minute.

Important information:

We need to find the unit rate.

Divide the distance by time to find the unit rate.

Answer:

Yesterday I squeezed 2 kilos of apples in a barrel.

Today I have picked 5 extra kilos of apples and save them in a basket.

By the end of the day, I want to squeeze some of them and add to the barrel.

Apple juice from the barrel is valued 3 times the same amount of raw apples.

I want to find how many apples I can squeeze today (x) such that the value of the remaining raw apples is equivalent to the total value of produced apple juice.

Step-by-step explanation:

The equation is 5-x = 3 * (x + 2).

If x is the amount of apple to squeeze (in kilos) then 5-x is the remaining raw apples and x+2 is the total quantity of juice.

Since that juice is valued 3 times the raw apples we obtain the equivalence defined in the equation above.
