Solve the equation above
saveliy_v [14]

Answer:

X = -2

Step-by-step explanation:

1/2 X (5X-8) = -9

multiply both sides of the equation by 2

2 X 1/2 X (5X - 8) = 2 X (-9)

1 X (5X - 8) = 2 X (-9)

Reduce the numbers with the greatest common divisor 2

5 x -8 = 2 x (-9)

5 x -8 = -18

Move constant to the right by adding its opposite to both sides

5X -8 + 8=-18 + 8

Then eliminate the opposites

5X = -18 + 8

Calculate the sum

5X = -10

Divide both sides of the equation by 5

5X DIVIDE 5 = -10 DIVIDE BY 5

X = -10 DIVIDE BY 5

X = -2

Evaluate.
snow_lady [41]

Replace a and b with their given values:

(2(3/5) -1/3) / -6.75/15

2 x 3/5 = 6/5

6/5 - 1/3 = 18/15 - 5/15 = 13/15

13/15 / -6.75/15 = 13/15 x 15/-6.75  = (13 x 15) / (15 x -6.75) = 195/-101.25  = -1 25/27

Answer: -1 and 25/27

D’Quan’s grandmother made a quilt for his bed. The quilt is
damaskus [11]
One Square Meter= 10.764 Square Feet.
The total area of the quilt in meters is 4.465m^{2}
As you're looking for square feet, you've then got to multiply this by 10.764
4.465*10.764= 48.06086 square feet.
Rounded, this is 48.06 square feet.
Hope this helps :)
