P^2 + p - 6 -(p^2 - 4p) =
p^2 + p - 6 - p^2 + 4p =
5p- 6 <==
5p - 6 - (?) = p - 9......4p + 3 <==
Let x be the tens and y be the ones digits.
The product of the number is then: 10x + y
The product is 1/2, so you need to multiply the product by 2 and the number:
10x + y = 2(x+y)
10x + y = 2x + 2y
Subtract 1 y from both sides
10x = 2x + y
Subtract 2x from
Both sides
8x = y
X has to be 1 , which would make y 8
The product number becomes 18
Since the product is 1/2, multiply by 2:
18 x 2 = 36
3 x 6 = 18
The answer is 36
Answer:2\cdot \frac{x}{x}-3-2x-\frac{5}{x^2}-8x+15=-\frac{3}{x}-5\quad :\quad x=\frac{1}{2},\:x=\frac{7+\sqrt{149}}{10},\:x=\frac{7-\sqrt{149}}{10}\quad \left(\mathrm{Decimal}:\quad x=0.5,\:x=1.92065\dots ,\:x=-0.52065\dots \right)
Step-by-step explanation:
X+4y+x+y= 4x+y=180
simplify by adding like terms
2x+5y= 4x+y=180
Subtract y from each side
2x+4y=4x=180
Subtract 2x from each side
4y=2x=180
y=180/4=45
x=180/2=90
