Let x be the price of the tv. The total cost is x + 0.07x You can factor out the x to get x(1 + 0.07) = 1.07x. The total cost of a tv that costs $x is $1.07x.

3/8 of an inch per month means 3 inches in 8 months 3/8 * 8/1 = 24/8 = 3. One foot is 12 inches, it will rain 3 inches in 8 months, 6 inches in 16 months, and 12 inches in 32 months. ---- set up the problem ------ 3/8 inches/per...

After plotting each line, find the equation of each line. Reading the y-intercept and finding the slope is straight forward. See http://www.hwmath.net/dev/alg/inequal1220.jpg Next, the equations shown are for the boundary lines and they are written in slope intercept...
First find the line where y = -x +4. Because the inequality in the problem is <, draw a doted or dashed line to show that the actual line will not be part of the solution. http://hwmath.net/dev/alg/-xplus4.jpg Next, decide which side of the line should...
To best understand this problem, draw a graph and plot the point A(-1,2). Then draw a horizontal line where y=7. There must be a x value along this line that will make the distance from A to a point B(p,7) that will be 13 units apart. You can see from the graph, that the point...
Let the side length of the longer leg be s. The shorter leg is (s -5) and the hypotenuse is (s +5) since a2 + b2 = c2 s2 + (s - 5)2 = (s + 5)2 s2 + s2 - 10s + 25 = s2 + 10s + 25 now subtract s2 from...
A path of 50 square stones each 25 cm in length with have a total length of 50 * 25 cm. To covert the units to meters divide by 100. (50 * 25)/100.
Let the rate Marilyn drives be x km/h. Then Craig drives (20 + x) km/h. Rate x time = distance so Marilyn drives (x km/h) for some time(t) and goes 225 km. Craig drives (x + 20) km/h for some time(t) and goes 325 km. The time Marilyn drives...
If the data is normally distributed, then draw a picture, draw a picture, draw a picture. Draw a normal distribution label the mean label + 1 and -1 standard deviations, 68% of the data will be between 58 and 62 because the standard deviation is 2. Next...
Simplify where possible, -6 + 23 = 17 so rewrite the inequality as 13 > 17 + x, then to get x all by itself on one side of the inequality, subtract 17 from both sides. 13 - 17 > 17 - 17 + x Then simplify both sides -4 > x Check the...
A line that is perpendicular to the line y = -9x -1 will have a slope of positive 1/9. If a line goes through the point P(0,0) then the y-intercept will be 0. So now you know the slope of the line, and the y-intercept. The format for the equation of a line, in slope intercept form is y = mx...
The area of a rectangle is length x width so l * w = 576 If l = 4w the 4w * w = 576 divide both sides by 4 w * w = 144 or w squared = 144, so take the square root of both sides to find w. After you find w, then find the length which is 4 x...
This is not from perspective of a writer or writing, but there are advances in making clothes more friendly to personal computing devices. Two examples, sweatshirts/hoodies that have spaces to embed the wires for your headphones and a place to hold a phone/ipod/mp3 player where you can control...
What was the average?
Let x represent what they made last year, in millions of dollars. x + 4.1 = 2.3 Solve for x by subtracting 4.1 from both sides. It looks like they lost money last year.
Is there part of the question missing? Another point, or the slope?

Let P be the marked price, then the cost to Raju was (0.8)P, which represents a 20% discount. When Raju sold the watch, his profit was P - .8P = 0.2 P The percent gain for Raju = (Profit/Cost)* 100 = (.2p/.8P)*100 = 25% Plug in some numbers...
