X^2 + y^2 = 5
y = 2x

The second equation is solved for y, so substitute it in the first equation.

x^2 + (2x)^2 = 5

x^2 + 4x^2 = 5

5x^2 = 5

x^2 = 1

x^2 - 1 = 0

(x + 1)(x - 1) = 0

x = -1 or x = 1

Now substitute both values of x in the second equation and solve for y.

y = 2x

For x = -1

y = 2(-1)

y = -2

For x = 1

y = 2(1)

y = 2

Solution: (-1, -2), (1, 2)

Compute the number of vinyl tiles, measuring 28 inches on each side, needed to tile a kitchen measuring 102 ft. by 18 ft.
ratelena [41]

Answer:

338 tiles

Step-by-step explanation:

First, convert the measurements of the kitchen from feet to inches by multiplying each measurement by 12.

102 * 12 = 1224     18 * 12 = 216


Now multiply these answers together.

1224 * 216 = 264,384 square inches


Now find the area of the vinyl tiles.

28 * 28 = 784 square inches


Now find how many 784 square inch tiles are needed to cover a 264,384 square inch kitchen.

264,384 / 784 = 337.224


Since you can't buy part of a tile, round your answer up.

338 tiles

A bolt has 16-1/2 turns per inch. How many bolts would be in 2-1/2 inches?
ohaa [14]

Answer:

41 1/4

Step-by-step explanation:

Change 16  1/2 to a mixed number

16 1/2 = (2*16+1)/2 = 33/2

Change 2 1/2 to a mixed number = (2*2+1)/2 = 5/2

Multiply the turns per inch by the inches

33/2 * 5/2 =165/4

Change this back to a mixed number

4 goes into 165 41 times

41*4 = 164   there is 1 left over

41 1/4
