Answer:

A

Step-by-step explanation:

I've forgotten the exponent rules for exponent operations, but one way to do this is to find the value of the expression given (2^-5 * 2^7)^-3 (which is equal to 0.015625) using a calculator, then use your calculator to find which answer choice is equal to the expression given AKA 0.015625. I did this and got A, but you should probably still look up exponent rules for future reference. Trust me, this question is actually WAY easier than what it probably looks like to you, as long as you know the exponent rules. :)

Give me Brainliest and have a great day! :)

Cheers!

What does x equal 2(x-3)=14
Leno4ka [110]

Answer: x = 10

Explanation: To solve this equation for <em>x</em>, we start by distributing the 2 through the parentheses on the left side.

So we have 2 times <em>x</em> which is 2x and 2 times -3 which is -6. So our equation now reads 2x - 6 = 14.

Solving from here,

we add 6 to both sides of the equation and we have 2x = 20 and dividing both sides by 2, we find that <em>x = 10</em>.

We can check our answer by substituting a 10 back in for <em>x</em> in the original equation and we have 2(10 - 3) = 14.

10 - 3 is 7 so we have 2(7) = 14 or 14 = 14 which is a true statement so our answer checks.

Someone help me out please

Hey there!

150 = 8x + 6y

↠ 150 = 8x + 6(9)

↠ 8x + 6(9) = 150

↠ 8x + 54 = 150

SUBTRACT 54 to BOTH SIDES

8x + 54 - 54 = 150 - 54

CANCEL out: 54 - 54 because that gives you 0

KEEP: 150 - 54 because helps solve for x

↣150 - 54 = 96↢

NEW EQUATION: 8x = 96

DIVIDE 8 to BOTH SIDES

8x/8 = 96/8

CANCEL out: 8/8 because that gives you 1

KEEP: 96/8 because that gives the value of x

96/8 = x

x = 12

Answer: x = 12

Good luck on your assignment and enjoy your day!
