1/3 a + 2 < -2
1/3a < -4
a < -4*3
a < -12 Answer
Assuming the order doesn't matter it would be 10c6 = 210 ways
He will use more tiles because 1/3 is smaller than 1/2 and the smaller the tiles the more you need to fill the place up.
Answer: 2.25
Divide the corresponding values. You'll divide figure 2's length over figure 1's corresponding length. So 18/8 = 2.25
This means each side of figure 2 is 2.25 times larger than the corresponding side for figure 1
Answer:
40, 60 and 80 degrees.
Step-by-step explanation:
Let the smallest angle be x degrees. Then:
The 3 angles are x, x + 40 and x + 20.
As there are 180 degrees in a triangle:
x + x + 40 + x + 20 = 180
3x = 180 -40--20 = 120
x = 40 degrees.
The other 2 angles are 60 and 80 degrees.
