Answer:

8x+12+12x+8=0

20x+20=0

20x=-20

x=-1

Answer:

20

Answer:

Yes

Step-by-step explanation:

Because, without the x, it makes them both a horizontal line. Therefore, never intersecting. Meaning, parallel.

Answer:

No solution

Step-by-step explanation:

Answer:

To do this, just do 12 divided by 4.80 = 2.5 dollars per can at Corner Grocery, and at Max's Market 15 divided by 5.25 = 2.85 per can. So the Corner Grocery has a better unit price by 35 cents.

Answer:

x = 4

Step-by-step explanation:

2x + 15 = 43 - 5x

2x + 5x = 43 - 15

7x = 28

x = 28/7

x = 4

Answer:

x = 4

Step-by-step explanation:

Step 1: Simplify both sides of the equation

2x +15 = 43 - 5x

2x +15 = 43 + - 5x

2x +15 = - 5x + 43

Step 2: Add 5x to both sides

2x + 15 + 5x= - 5x + 43 + 5x

7x +15 = 43

Step 3: Subtract 15 from both sides.

7x +15 -15 = 43 - 15

7x = 28

Step 4: Divide both sides by 7.

7x/7 = 28/7

Therefore the X = 4

Answer: x = 81, y = 17

Step-by-step explanation:

x + y = 98

x/y = 4/13/y

x/y = 4y + 13/ y

x = 98 - y

(98 - y) / y = (4y+ 13) / y

Therefore

98 - y = 4y + 13

Collect like terms

-4y - y = 13 - 98

-5y = -85

Divide both sides by-5

y = 17

x = 98 - y

x = 98 - 17

x = 81

The two numbers​ x and y are 81 and 17 respectively.

Quotients are the number that is obtained by dividing one number by another number.

Dividend ÷ Divisor = Quotients

Given that the sum of two numbers is 98.

Let x and y be the two numbers

x + y = 98

Thus, the larger number is divided by the smaller quotient is 4 with a remainder of 13.

x/y = 4/13/y

x/y = 4y + 13/ y

x = 98 - y

(98 - y) / y = (4y+ 13) / y

Therefore,

98 - y = 4y + 13

Collect like terms;

-4y - y = 13 - 98

-5y = -85

Divide both sides by-5;

y = 17

x = 98 - y

x = 98 - 17

x = 81

Therefore, the two numbers​ x and y are 81 and 17 respectively.

4x-3y=18

3y=4x-18

  y=4/3x-6

By y=mx+c , Slope of line 4x-3y=18 is 4/3

Since the required line is perpendicular to the line 4x-3y=18 ,

slope of required line * Slope of line 4x-3y=18 = -1

slope of required line = -1/(4/3) = -3/4

Since the required line passes through (8,-8)

By point-slope form,

y-(-8)= -3/4(x-8)

      y= -3/4x-2

4 : 5 ----> 4x, 5x

4x + 5x = 4.5

9x = 4.5

x = 4.5 / 9

x = 0.5

4x
