Thepotemich [5.8K]

Answer:

$9.00

Step-by-step explanation:

If the price is at 30% discount, this means it is 100-30 = 70% of the original price.

70 \%  \ of \ original \ price = \$ 6.30\\\\\ original \ price = 6.30 \div 70 \%\\\\= 6.30 \times \frac{100}{70}\\\\=\frac{630}{70}\\\\= 9

Hence, original price is $9.00.

Determine the solutions of the equation:
jekas [21]

The solutions of the equation are x = 15 and x = -20

<h3>How to determine the solutions of the equation?</h3>

The equation is given as:

the absolute value quantity two fifths times x plus 1 end quantity minus 7 equals 0

Rewrite the equation properly as:

|2/5x + 1| - 7 = 0

Add 7 to both sides

|2/5x + 1| = 7

Remove the absolute bracket

2/5x + 1 = 7 and 2/5x + 1 = -7

Subtract 1 from both sides

2/5x = 6  and 2/5x = -8

Solve for x

x = 15 and x = -20

Hence, the solutions of the equation are x = 15 and x = -20

If triangle ACD ~ triangle ABE, find the value of x.
alina1380 [7]
Answer:

x = 16

Explanations:

Since △ACD ~ △ABE, it means that:

CD/AD = BE/AE..........(*)

CD = 3x + 8

AD = AE + ED

AD = (x - 1) + 27

AD = x + 26

BE = 20

AE = x - 1

Substituting CD, AD, BE, and AE into equation (*)

(3x+8)/(x+26) = 20/x-1

Cross multiply:

(3x+8)(x-1) = 20(x+26)

3x² - 3x + 8x - 8= 20x + 520

3x²- 15x - 528 = 0

Divide through by 3

x² - 5x - 176 = 0

Solving the quadratic equation above for the values of x

x² - 16x + 11x - 176 = 0

x(x - 16) + 11 (x - 16) = 0

(x - 16)(x + 11) = 0

If x - 16 = 0

x = 16

If x + 11 = 0

x = -11

x cannot be -11 because x = -11 will make side CD and AE to be negative, and the sides of a triangle cannot be negative.

Therefore, x = 16
