The weight of an object is equal to 3\4 of its own weight plus 3\4of a pound. What is the weight?
Phoenix [80]

Answer:

The weight of the object is 3 kg.

Step-by-step explanation:

<u>Step 1: </u>

Let object weight be x kg.

Now, as per the available data,

3/4 kg + 3/4 (x kg) = x kg

<u>Step 2: </u>

3/4 (1 + x) = x

1 + x = 4x/3

1 = x (4/3 - 1)

x = 1 / (1/3)

x = 3

Weight of Object is 3 kg.

<u>Step 3: </u>

Let's check if this value satisfies the first equation.

3/4 + 3/4 x 3 = 3/4 + 9/4 = 12/4 = 3

Hence proved.

Need help with factoring, x squared minus 8x +15
wariber [46]

Answer:

(x-3)(x-5)

Step-by-step explanation:

X^2-8x+15

Break the expression into groups

(x^2-3x)+(-5x+15)

Factor out x from x^2-3x

Factor out -5 from -5x+15: -5(x-3)

=x(x-3)-5(x-3)

Factor out common term x-3

=(x-3)(x-5)
