Bad White [126]

Answer:

68%

Step-by-step explanation:

The increase is (62 - 37), or 25, ounces. Comparing this to the original quantity (37 oz), we divide 25 oz. by 37 oz., obtaining 0.676 (a ratio). Multiplying this ratio by 100%, we get 68% (to the nearest percent).

Elimination method<br> 4x-2y=48<br> 2x+6y=-18

yulyashka [42]

$4x-2y=48\\ \\ 2x+6y=-18$

First we'll multiply the second equation by -2

$-2\cdot (2x+6y)=-2\cdot -18\\ \\ -4x-12y=36$

Now let's add the new equation and the first one.

$(4x-2y)+(-4x-12y)=48+36\\ \\ 4x-4x-2y-12y=48+36\\ \\ -14y=84\\ \\ y=\frac { 84 }{ -14 } \\ \\ y=-6$

We found y's value. We'll plug it in one of the equations to find x's value.

$y=-6\\ \\ 4x-2y=48\\ \\ 4x-2\cdot -6=48\\ \\ 4x+12=48\\ \\ 4x=48-12\\ \\ 4x=36\\ \\ x=\frac { 36 }{ 4 } \\ \\ x=9$

Solution ;

(9, -6)

What is the value of x in the equation 7(4x+1)−3x=5x−13?

Citrus2011 [14]

Answer:

x = -1

Step-by-step explanation:

7(4x+1)−3x=5x−13

Distribute

28x +7 -3x = 5x -13

Combine like terms

25x+7 = 5x-13

Subtract 5x from each side

25x-5x +7 = -13

20x +7 = -13

Subtract 7 from each side

20x+7-7 = -13-7

20x = -20

Divide by 20

20x/20 = -20/20

x = -1
