Answer:

D. ( 3.6 , 2.2)

Step-by-step explanation:

Given

x + y = 5.8....equation 1

y = 2x - 5 ......equation 2

Putting equation 2 in equation 1

x + 2x - 5 = 5.8

3x = 5.8 + 5

3x = 10.8

Therefore x = 3.6

Now

y = 2 * 3.6 - 5

= 7.2 - 5

= 2.2

Hope it will help you.

Alexus [3.1K]

Answer:

B) 1

Step-by-step explanation:

Given:

8^{-3}\times 8^{-2}\times8^5

We need to solve the given expression.

Now We know that when base of the exponents then the law of indices applied for the same.

Now According to Law of Indices.

x^a\times x^b = x^{a+b}

On Solving the above expression we get;

8^{-3+(-2)+5}\\\\8^{-3-2+5}\\\\8^{-5+5}\\\\8^0\\\\\textrm{Now Again by law of indices;}\\\\a^0 =1\\\\Hence\ 8^0 = 1

Hence The Simplified form of given expression is 1.

I NEED HELP ASAP!!<br><br> Subtract.<br><br> -30-27= ?<br><br> -5-(-4)= ?
pashok25 [27]
-30-27= -57
When both numbers are negative, they are “added” in a sense, but remain negative.

-5-(-4)= -1
You have to multiply the (-4) by the “invisible” -1 on the outside before you add/subtract.
