Hello there!

So basically all you have to do is remove these signs that makes it complicated. However, you must know the rules in order to do so.

The rules says:

When you have plus sign * negative sign, the answer will carry the negative sign.

So let's start!

20 + (-3.05) + (-9.5)

= 20 - 3.05 - 9.5

= 16.95 - 9.5

= 7.45

I hope this helps and please let me know if you have questions about the answer.

Good luck with your studies!

Happy New Year!

It would be 7.45 since the -3.05 and the -9.5 together would equal -12.55 which subtracted from 20 would equal 7.45

Please help me im almost done!​
kumpel [21]

Answer:

if you divide both sides of -5x > 0 you get z > <em>0. </em>This is incorrect because if you choose a value from the possible solutions such as z=6 and substitute it into the original equation you get <em>-30</em> > 0, which is <em>not true</em>

I put the answers in bold

hope this helps!

X*2+1=10 then x=? Tell me the value of x
Trava [24]

Answer:

<h2>4.5</h2>

Step-by-step explanation:

x \times 2 + 1 = 10

2x +  1 = 10

Move constant to R.H.S and change its sign

2x = 10 - 1

Subtract the numbers

2x = 9

Divide both sides of the equation by 2

\frac{2x}{2}  =  \frac{9}{2}

Calculate

x = 4.5

Hope this helps..

Best regards!!
