What value will make the equation true?
Viktor [21]

Answer:

-.6

Step-by-step explanation:

-2.1 - x = -1 1/2

Change the fraction to a decimal

-2.1 -x = - 1.5

Add 2.1 to each side

-2.1 -x+2.1 = -1.5 +2.1

-x = .6

Multiply each side by -1

x = -.6

Select the equivalent expression . ( 8^ -5 2^ -2 )^ -4 =?
Vikki [24]

Answer: C

Step-by-step explanation:

When there is division inside a set of parentheses, you can distribute the power to each term. When you take a power to another power, you multiply the powers.

-5 x -4 = 20

-2 x -4 = 8

So your answer is:

\frac{8^2^0}{2^8}

Help me pls !!!<br><br> answer all pls

1. We assume, that the number 128 is 100% - because it's the output value of the task. 
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 128 is 100%, so we can write it down as 128=100%. </span>
<span>4. We know, that x is 51% of the output value, so we can write it down as x=51%. </span>
5. Now we have two simple equations:
1) 128=100%
2) x=51%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
128/x=100%/51%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 51% of 128

128/x=100/51
<span>(128/x)*x=(100/51)*x       - </span>we multiply both sides of the equation by x
<span>128=1.96078431373*x       - </span>we divide both sides of the equation by (1.96078431373) to get x
<span>128/1.96078431373=x </span>
<span>65.28=x </span>
x=65.28

<span>now we have: </span>
<span>51% of 128=65.28</span>
