10/15 divided by 5 = 5/10

Both 10 and 15 can be divided by 5.

10/15 = 2/3

2 and 3 can only be divided by 1 now. So you keep dividing till you can only divide by 1.

Follow the directions to solve the system of equations by elimination. 8x + 7y = 39 4x – 14y = –68 Multiply the first equation t

Hitman42 [59]

Answer:

The solution is ( 1/2 , 5)

Step-by-step explanation:

∵ 8x + 7y = 39 ⇒ (1)

∵ 4x - 14y = -68 ⇒ (2)

Multiply (1) by 2

16x + 14y = 78 ⇒ (3)

Add (2) and (3)

∴ 20x = 10 ⇒ x = 10 ÷ 20 = 1/2

∴ x = 1/2

By substitute in (1)

8(1/2) + 7y = 39 ⇒ 7y = 39 - 4 = 35 ⇒ y = 35 ÷ 7 = 5

∴ y = 5

∴ The solution is ( 1/2 , 5)

To check:

8(1/2) + 7(5) = 4 + 35 = 39 = R.H.S

4(1/2) - 14(5) = 2 - 70 = -68 = R.H.S

Which of the following is a factor of 7x2 - 12x - 4? (6 points)

grin007 [14]

Answer:

We conclude that 'None of the above' is the correct answer.

Step-by-step explanation:

Given the expression

$7x^2\:-\:12x\:-\:4$

Breaking the expression into groups

$7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)$

Factor out $x$ from $7x^2\:+\:2x$

$=x\left(7x+2\right)$

Factor out -2 from $\left(-14x-4\right)$

$=-2\left(7x+2\right)$

so the expression becomes

$7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)$

$=x\left(7x+2\right)-2\left(7x+2\right)$

Factor out the common term $7x+2$

$=\left(7x+2\right)\left(x-2\right)$

Therefore, from the given options, we conclude that 'None of the above' is the correct answer.
