it is true because al triangles angles MUST add up to 180
3(x-4)>= 5x+2
Distributing 3 on x-4
3(x)-3(4)>=5x+2
3x-12>=5x+2
Now we need to move x terms together and the numbers together and for that we subtract 5x to both sides and add 12 to both sides
-2x >=14
Now we need to get rid of -2, and for that we divide both sides by -2 and on dividing by negative number, the sign of inequality change , that is
x<=-7
Answer:
x=16 and y=9
Step-by-step explanation:
2y+30=3y+21[Diagonals of parallelogram are equal]
30-21=3y-2y
y=9
3y=2x-5[Diagonals of parallelogram are equal]
3×9=2x-5
27=2x-5
2x=27+5
x=32/2=16
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
