12 + 16 = 28

28/2 = 14

So it will take them both 14 hours if they paint the room together.

Hope this Helps!!

The value of 3 in 46.132 is how many times the value of the 3 in 8.553<br><br>A 10<br>B 1 <br>C 1/10

kifflom [539]

Answer:

The value of 3 in 46.132 is 10 times the value of 3 in 8.553.

Step-by-step explanation:

The value of 3 in 46.132 is in hundredth's place.

The value of 3 in 8.553 is in thousandths place.

We can write as :

For 46.132, its value is $\dfrac{3}{100}$ and for 8.553 its value is $\dfrac{3}{1000}$ .

Taking,

$\dfrac{\dfrac{3}{100}}{\dfrac{3}{1000}}=10$

So, the value of 3 in 46.132 is 10 times the value of 3 in 8.553. Hence, the correct answer is A.

If the jacket cost 45.00 and there is 25%off how much will the jacket cost now

Ivan

69. The jacket is said to have an original price of 45.00 dollars. Now, is was given a 25% off. Solve for the final cost of the jacket after the discount is applied. => 25% = 25% / 100% = 0.25 => 45.00 * .25 = 11.25 dollars is the discount. Now, let’s subtract the value of 25% by the original value. => 45 – 11.25 = 33.75 dollars. This is now the costs of the jacket after the discount is applied.

Two numbers such that the greater number is 75 percent more than the lesser number

victus00 [196]

<h2>Greetings!</h2>

If x = the first number (equal to 1x) then the second number is 75% more than this.

This means the value of the bigger number is 100 + 75 (because 100 is the starting number and 75 is the percent bigger)

This can be shown with the following equation:

Amount * $\frac{percentage}{100}$

x * $\frac{175}{100}$ = 1.75x

1.75x is the value of the bigger number.

<h2>Hope this helps!</h2>

In order to solve the following system of equations by addition, which of the

Pavlova-9 [17]

Answer:

Multiply the top equation by -3 and the bottom equation by 2

Step-by-step explanation:

Given <u>system of equations</u>:

$\begin{cases}4x-2y=7\\3x-3y=15 \end{cases}$

To solve the given system of equations by addition, make one of the variables in both equations <u>sum to zero</u>. To do this, the chosen variable must have the <u>same coefficient</u>, but it should be <u>negative</u> in one equation and <u>positive</u> in the other, so that when the two equations are added together, the variable is <u>eliminated</u>.

<u>To eliminate the </u><u>variable y</u>:

Multiply the top equation by -3 to make the coefficient of the y variable 6:

$\implies -3(4x-2y=7) \implies -12x+6y=-21$

Multiply the bottom equation by 2 to make the coefficient of the y variable -6:

$\implies 2(3x-3y=15) \implies 6x-6y=30$

Add the two equations together to <u>eliminate y</u>:

$\begin{array}{l r r}& -12x+6y= &-21\\+ & 6x-6y= & 30\\\cline{1-3}& -6x\phantom{))))))} = & 9\end{array}$

<u>Solve</u> for x:

$\implies -6x=9$

$\implies x=-\dfrac{9}{6}=-\dfrac{3}{2}$

<u>Substitute</u> the found value of x into one of the equations and <u>solve for y</u>:

$\implies 3\left(-\dfrac{3}{2}\right)-3y=15$

$\implies -\dfrac{9}{2}-3y=15$

$\implies -3y=\dfrac{39}{2}$

$\implies y=-\dfrac{39}{2 \cdot 3}$

$\implies y=-\dfrac{13}{2}$

Joy is reading a 352-pagenovel forher summer reading prodject on monday she reads 3/8 of the novel on tuesday she reads 28 pages

schepotkina [342]

Answer:

104 Pages

Step-by-step explanation:

on Monday she reads 3/8 of the novel which means

x 352 = 132 pages

on Tuesday she reads 28 pages, doesn't require any calculations.

on Wednesday she reads 1/4 of the novel,

x 352 = 88

Just add all of that,

132+28+88=248 Pages

Subtract the novel pages by the read pages value

352-248=104pages.
