I'm having a hard time figuring this out I've tries multiple ways but can not get it please help

9.6

Step-by-step explanation:

Plugging in the info given, we get:

2(4) - (2/5)(-4) = 8 - (-8/5) = 8 + 8/5

From here, you need to make the denominators of both numbers the same in order to combine them further. Currently, as a fraction, it looks like this:

8/1 + 8/5

To make the denominators the same we can just multiply 8/1 by 5/5 (this is the same as multiplying by 1, which essentially allows us to change it's form without changing its value). Doing that gives:

(8/1)(5/5) + 8/5 = (8•5)/5 + 8/5 = 40/5 + 8/5

= (40+8)/5 = 48/5

So 48/5 is the answer. But the website wants you to put it into decimal form. This can be done using a calculator, but let's pretend we don't have one...

Decimals work by using whole numbers divided by multiples of 10 and can be visualized as moving a decimal left (or right) between numbers. For example:

1/10 = 0.1

4/10 = 0.4

23/10 = 2.3

13/100 = 0.13

59/1000 = 0.059 and so on.

So if we can multiply 48/5 by something to make the denominator some multiple of 10, we can simply move the decimal left once and that's our answer. 2/2 should work here:

(48/5)(2/2) = (48•2)/(5•2) = 96/10 or 96.0/10

96.0/10 = 9.6

So your decimal answer is 9.6.

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
