Answer:

The value of x is 0.624.

Property used: Symmetric property of equality

Step-by-step explanation:

The expression to be solved is:

$f (x) = 2.5\cdot (6.25x+0.5)-11$

Compute the solution as follows:

$f (x) = 2.5\cdot (6.25x+0.5)-11$

$=(2.5\times 6.25\ x)+(2.5\times 0.5)-11$

∵ Distributive property (a (b + c) = ab + ac)

$=15.625x+1.25-11\\=15.625x-9.75$

Substitute equation equal to 0 to compute the value of x as follows:

$0=15.625x-9.75\\\\15.625x=9.75\\\\$

∵ Symmetric property of equality if a = b then b = a

$x=\frac{9.75}{15.625}\\\\x=0.624$

Thus, the value of x is 0.624.

HELPPPPP ANSWER GETS BRAINLIEST

Murrr4er [49]

Answer:

56 degrees

Step-by-step explanation:

If you look at the m<KLN you can see that it is an acute angle. So, with this being said you have to know that the measure KLN is going to be less than 90 degrees. So you would subtract 180 and 124 and you would get 56 degrees.

I hope this helps :)
