Just add 5 on both sides:
x-5>10
x>15
Answer:
11.95 dollars
Step-by-step explanation:
Cost of one LED bulb = 6.95 dollars
Cost of changing one bulb = 3 dollars
Life of each bulb = 5 years.
In 10 years, only one time after 5 years the bulbs would have been changed
Hence cost of 100 lamps = 695 and
cost of changing once = 500
Total cost = 1195 dollars for 11 years
Divide this by 10 years to get average cost per year
Cost of 100 lamps per year = 1195/100 = 11.95 dollars
<span><span> combine like terms4ln(x) = 8
</span><span>divide both sides by 4.ln(x) = 2
</span><span>exponentiate both sides.<span>eln(x) = e^2</span>
</span><span>inverse property of exponents and logs <span>x = e^<span>2

Answer:
Step-by-step explanation:
We are given the equation
We want to solve for x, therefore we must isolate x on one side of the equation.
14 is being added to 3x. The inverse of addition is subtraction. Subtract 14 from both sides of the equation.
x is being multiplied by 3. The inverse of multiplication is division. Divide both sides of the equation by 3.
Let's check our solution. Plug 7 in for x and solve.
This checks out, so we know our solution, <u>x=7 </u>is correct.
