The first step would be to subtract 5 from both sides. We have to leave x alone so subtract five from both sides which will leave us with x=22

For the next one we would have to divide 3 by -4 to get w=1.3 Infinite so the 3 would have a small dash on top.

Lizabeth says that (-12)^3 equals a positive number because the product if two negative integers is a positive integer. Do you a
Alika [10]

Lizabeth's reasoning is faulty because in this expression, it's not multiplying 2 negative integers, its multiplying 3 negative integers. And while the product of 2 negative integers equals a positive, the positive product multiplied by another negative will equal a negative.

The ratio of black marbles to red marbles is 3:2. If there are a total of 25 marbles in a bag,
kumpel [21]

Answer:

15 black marbles

Step-by-step explanation:

So its. A ratio (basically a fraction)

3/2

we add them up so we know how much marbles but not which kind

so we get 5

now we know for every 5 batches there is 3 black and 2 red

so we divide 25/5 to get 5

now we know there are 5, 5 batches of black ad red marbles.

now black is 3 of them so we multiply 5(3) which is 15

Now red is 2 of them so we multiply 5(2). Which is 10

now to check, if we add them up, they equal to 25 which is correct.

basically add the fraction, divide that by the original number, time the quotient by each number in the fraction.

Find the volume of the rectangular prism.<br> 9 cm<br> 9 cm<br> 9 cm
cricket20 [7]

Answer:

3672 cm^3

Step-by-step explanation:

There is a typo in the question, the lengths of the sides of the prism are:

24 cm

9 cm

17 cm​

(otherwise, if all sides were 9 cm, it would be a cube, not a prism)

The volume of a rectangular prism is given by:

V=l\cdot w\cdot h

where:

l is the length of the prism

w is the width of the prism

h is the height prism

In this problem,

l=24 cm (length)

w=9 cm (width)

h = 17 cm (height)

Therefore, the volume of the prism is:

V=24\cdot 9 \cdot 17 = 3672 cm^3
