Answer:
x=7
Step-by-step explanation:
Solve.
7x-5x-3=x+4
Calculate like terms.
7x-5x=2x
Rearrange.
2x-3=x+4
Apply inverse addition.
2x-3+3=x+4+3
2x=x+7
Isolate 2x by subtraction.
2x-x=x-x+7
x=7
The three items cost altogether is : 111.32 + 28.75 + 73.21 = 213.28
So, he must work 213.28 : 8.75 = 24.3748571429...
Since if he works 24 hours, he wouldn't have enough money to buy the 3 items, so he must work 24 + 1 = 25 hours.
Recheck : 25 x 8.75 = 218.75 ( > 213.28)
K Value is a steady state of the heat flow through a unit area of a homogeneous material induced by the unit temperature gradient. It can be determined by the flow of heat from a hotter surface to a colder surface. It is used to describe British thermal unit (BTU) per hour
Initial value is when x=0
that is
f(0)=a(b^0) or
f(0)=a(1) or
f(0)=a
remember that x^0=1 for all values of x
