$3(x-1)-2(2x+1)=8(x-1)$ Distribute 3 to x and -1, -2 to 2x and 1, and 8 to x and -1.
$3x-3-4x-2=8x-8$ Simplify
$-x-5=8x-8$ Add x and 8 on both sides.
$3=9x$ Divide by 9
$x= \frac{3}{9} = \frac{1}{3}$
$\frac{1}{3}$ is your answer

Answer:

Grey have to pay $157.5 on monthly basis to keep his home insured.

Step-by-step explanation:

Grey purchased a house = $450,000

Annual Insurance premium = $0.42 per $100 of value.

We need to calculate monthly premium to pay such that home insured.

Now we calculate number of 100 in $450,000

Number of 100 = 4500

The premium value of 1 hundred = $0.42

Total value of 4500 hundred = 0.42 x 4500 = $1,890

Grey total premium in 1 year = $1,890

Now we find monthly premium

We know in 1 year total number of month is 12

In 12 month premium = $1,890

In 1 month premium = 1890÷12 = 157.5

Monthly premium for home insured = $157.5

Thus, Grey have to pay $157.5 on monthly basis to keep his home insured.

F(x) = x^2 + 7x-4 find the second derivative

Ulleksa [173]

We know that f(x) = 7x + 8. So, take the derivative of this function with respect to x.

This gives

f'(x) = 7

Now, you probably realized that the x value disappeared. This means that no matter what value of x you use, the derivative of this function is always going to be 7, even at x = 5. That is, the rate of change of this function is always going to be a rate of 7.

Imani sells shirts packed in boxes that are each 15in. x 10in. x 2in. Imani stacked 3 boxes and wrapped them with one piece of p

AnnZ [28]

Answer:

She used 600 square inches of paper.

Step-by-step explanation:

Since the box are 15 in x 10 in x 2 in and are stacked on top of each other, they form a bigger rectangular prism with 15 in x 10 in x 6 in. In order to calculate how much paper she used, we need to calculate the surface area of this prism, this is done by using the following formulla:

surface area = 2*width*length + 2*width*height + 2*length*height

surface area = 2*15*10 + 2*15*6 + 2*10*6 = 300 + 180 + 120

surface area = 600 in².

She used 600 square inches of paper.
