Step-by-step explanation:

-2-10=-5t+2t

-12=-3t

minus minus will be cancelled.

so,

12/3=4

Answer:

[tex] - 2 = - 5 t+ 10 + 2t \\ - 2 - 10 = - 5t + 2t \\ - 12 = - 3t \\ t = \frac{( - 12)}{( - 3)} \\ \boxed{t = 4}[/tex]

Answer:

x = 7

Step-by-step explanation:

TV = 17

TV = TU + UV

17 = 2x - 4 + 2x - 7

17 = 4x - 11

28 = 4x

x = 7

Answer:

3rd side = 6x + 3

Step-by-step explanation:

The perimeter must be the given trinomial

The 3rd side = Perimeter - sum of the two given sides.

side 1 = 4x^2 + 2x

side 2 = 3x^2 + 6

Sum = 7x^2 + 2x + 6

3rd side = Perimeter - sum

3rd side = 7x^2 + 8x + 9 - (7x^2 + 2x + 6)        Remove the brackets

3rd side = 7x^2 + 8x + 9 - 7x^2 - 2x - 6

3rd side = 6x + 3

Answer:

  27

Step-by-step explanation:

Evaluating this expression according to the order of operations is a straightforward calculator problem.

  = (81 ÷ 27)³ = 3³ = 27

__

You can also use the rules of exponents to simplify this before evaluating.

  (a^b)^c = a^(bc)

  (a^b)/(a^c) = a^(b-c)

__

  = ((3²)² ÷ 3³)³ = (3⁴ ÷ 3³)³ = (3¹)³ = 3³ = 27

The 3 in "513" is only 3. it's 1, 2, 3. If we do 3 x 10 it's 30

6,732

Step-by-step explanation:

First you put the numbers on top of each other.
I have:

     513

24,300

  6,732

     89.3

     5.43

Like that, lets see the three in 5.43 and 89.3 are tenths and hundreds so let those go.
    513

24,300

  6,732

Now go to the tens place, we need the three in to move one place to the left the only number that did that is 6,732, so there is your answer.

Step-by-step explanation:

whole number is any number represented by a complete unit  the whole

numbers greater than or equal to  0 and less than 8 are 0,1,2,3,4,5,6,7

Step-by-step explanation:

[tex] \frac{ \frac{1}{5} - \frac{1}{2} }{5 - 2} [/tex]

[tex] \frac{ \frac{2}{10} - \frac{5}{10} }{3} = \frac{ \frac{2 - 5}{10} }{3} = \frac{2 - 5}{10 \times 3} [/tex]

[tex] \frac{ - 3}{30} = \frac{ - 1}{10} [/tex]

Answer:

Do the subtractions in the numerator and denominator.

1/5 - 1/2 = 2/10 -5/10 = -3/10

5 -2 = 3

that equals -3/10 / 3 which equals -.1

OR multiply top and bottom by 10 which equals

-3 / 30 which also equals -.1

Answer:

one whole number two over fifteen or in decimal 1.1333

Step-by-step explanation:

this mathematics is very by explanations ,

Firstly, look for the LCM of the in the denominators ,that is look for the LCM of 3,15,5 which is 15 then a straight line keep the denominators result from the LCM under the straight line then use the denominators to divide 15 and multiply with numerators and then add the results and then you divide it by 15 and the result is 17 then 17/15 then you have one whole number,two over fifteen

Answer:

$73.78

Step-by-step explanation:

$68 + (68*8.5%)

$68 + (68*0.085)

$68 + $5.78

$73.78

The total price of the sweater will be $73.78.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

The percentage is just like the amount of that value but in between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.

Given that,

Price of sweater = $68

Percentage tax on the price of sweater = 8.5%

Now,

8.5% of 68 will be

⇒ 8.5 × 68/100 = $5.78

So, the total price will be

⇒ 68 + 5.78 = $73.78

Hence "The total price of the sweater will be $73.78".
