Answer:

x=0, -3/4

Step-by-step explanation:

We can solve by factoring. We will factor by GCF the greatest common factor. $8x^2$ and $6x$ share several factors in common:

they both share an x
they both share 2

I pull out 2x and I get $2x(4x+3)=0$ . I now set each factor equal to 0 and solve for x.

2x=0

x=0

4x+3=0

4x=-3

x=-3/4

tekilochka [14]

Answer:

Step-by-step explanation:

It appears that the number of bulbs produced on the first shift is quite a bit more than the second shift. 5.5 times more, actually. That means that the first shift's output is based on the second shift's output. Second shift produced an unknown number of bulbs, so we will call that number x. First shift produced 5.5 times more, so first shift produced 5.5x. The total number of bulbs produced between the 2 shifts is given as 16,250, so

x + 5.5x = 16,250 so

6.5x = 16,250 and

x = 2500

The second shift produced 2500 bulbs, and the first shift produced 5.5(2500) = 13,750 bulbs.

Answer:

$5820$ square inches

Step-by-step explanation:

For the rectangular prism in the middle:

$24*30=720*2=1140$

$10*30=300*2=600$

$1140+600=1740$

For the left triangular prism:

$10*24=240$

$26*30=780$

$24*30=720$

$10*30=300$

$240+780+720+300=2040$

For the other right triangular prism, it's the same.

Let's add now to find the surface for the whole ramp.

$1740+2040+2040=5820$

Hope this is helpful to you

4. A local DVD rental machine rents

Mrrafil [7]

It takes 16 movie rentals for both options to be the same price

<u>Solution:</u>

Given that, A local DVD rental machine rents movies out to customers for $5.75 per movie.

A digital movie company allows you to rent movies for $3.25 but requires a membership fee of $40.

We have to find how many movie rentals will it take for both options to be the same price?

Now, let the number of movies rented be "n"

Then, according to the given information,

$\begin{array}{l}{5.75 \times n=3.25 \times n+40} \\\\ {5.75 n=3.25 n+40} \\\\ {5.75 n-3.25 n=40} \\\\ {2.50 n=40} \\\\ {n=\frac{40}{2.5}=16}\end{array}$

Hence, it takes 16 movies to be the same price for both options.
