What is (- 4/5) x (- 5/8)

- 1/2

Step-by-step explanation:

(-4/5) × (- 5/8)

- 4/5 × - 5/8

First we mulitply across

The top and the bottom.

- 20 / 40

because -4 × -5 = +20

and -5 × -8 = +40

Now we simplify the fraction

- 20 / 40

= - 2 /4

= - 1/2

Because we have to simplify it and so I divided it by 10 first.

-20 ÷ 10 = -2 and -40 ÷ 10 = -4

Then I simplified it again by dividing it by 2.

-2 ÷ 2 = -1 and -4 ÷ 2 = -2

So finally we have:

-1/2

And we cannot simplify that anymore so that is the answer.

Hope that helped!

1/2

Step-by-step explanation:

since negative * negative= positive we multiply the top and bottom to get. 20/40 which simplifies

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
