42-x=58
or, -x=58-42
with change in side sign also chamges we change sides to make like terms in one side and unlike in amother side.
or, -x= 16
or,x=-16.
therefore x=-16...

a(n) = a+(n-1)d
here, a = 95, d= 90-95 = -5
a(n) = 95+(n-1)-5
a(n) = 95+5-5n
a(n) = 100-5n ......it's your answer
Answer:
z= 20.78
x=16.97
y=12.00
Step-by-step explanation:
To find z , we need cosine function
To find x and y , we need to find the height of the left triangle , i.e.
24 sin 30 = 12
then cos 45 = 12 /x
x= 12/ cos 45 = 16.97
sin 45 = y/x = y/ 16.97
y= 16.97 sin 45 = 12
.
hope it help

Answer:
To simplify a power of a power, you multiply the exponents, keeping the base the same. For example, (23)5 = 215. For any positive number x and integers a and b: (xa)b= xa· b.
