Answer: X is less than 3
Step-by-step explanation:
4x - 7 < 5
Add 7 to both sides:
4x < 12
Divide both sides by 4:
x < 3
Answer:
$6539
Step-by-step explanation:
52x 125.75 (52 weeks in a year)
= 6539
Operating cost
= Gas/Oil + Repair/Maintenance cost
= $1,700+ $650
= $2350
Miles driven
= $2350 ÷ $0.14
= 16,785.71
= 16,786 (round off)
Answer is A
I'd suggest you begin by subtracting 4 / (x-4) from both sides. Doing that would leave you with 1 / (x-4) - 2 / (x+2) = 0.
LCD is (x-4)(x+2). Mult. all three terms by (x-4)(x+2). The resulting equation is
x+2 - 2(x-4) = 0. Then x+2 = 2x - 8 => x = 10
Subst. 10 for x in the original equation to verify that 10 is indeed a solution.
We already know that the box has an area of 100 sq. inches. All we have to do now is subtract the area of the 4 circles from the area of the box.
The formula for a circle's area is 
. We already know the radius, so one circle has an area of 12.56 units (4π in terms of pi). There are 4 circles, making your final equation 
.
