What is the solution to the equation below? <br> 5 - n/2 = 12

Zarrin [17]

Step-by-step explanation:

5 - n/2 = 12

10/2 - n/2 = 12

n = (12 × (-2)) + 10

n = (-24) + 10

n = <u>-1</u><u>4</u>

Let's prove it :

$5 - ( - \frac{14}{2} ) \\ = \frac{10}{2} + \frac{14}{2} \\ = \frac{24}{2} \\ = 12$

Conclusion :

5 - n/2 = 12

5 - (-14/2) = 12

and

n = -14

The area of a parallelogram is 96 cm squared the height is 4 cm less than the length what is

andrey2020 [161]

Area of paralellogram=legnth times height

l=legnth
h=height
area=96

lh=96

h is 4 less than l
h=-4+l
sub
l(-4+l)=96
-4l+l^2=96
minus 96 both sides
l^2-4l-96=0
factor
(l-12)(x+8)=0
set to zero
l-12=0
l=12

l+8=0
l=-8, imossible, legnth cannot be negative, disreagard this soultion

legnth=12cm

Can someone walk me through how to evaluate this?

zubka84 [21]

Answer:

$\frac{1}{5}$

Step-by-step explanation:

For a negative exponent you always flip the number so instead of $5^{-1}$ it would be $\frac{1}{5^{1} }$ and 5 to the first power is 5

Now for $5^{0}$ any exponent with a zero it always equals 1

So $\frac{1}{5} * 1 = \frac{1}{5}$

Hope this helps!
