Answer:
2
Step-by-step explanation:
4x + 1 = 3x + 3
4x - 3x = 3 - 1
x = 2
2 x 4 + 1 = 9
3 x 2 + 3 = 9
Step-by-step explanation:
10x+1=12x-5
1+5=12x-10x
6=2x
6/2=2x/2
3=x
Answer:
10.24
Step-by-step explanation:
Area of a circle=sides²
Area of a circle=(3.2)²=3.2(3.2)=10.24
i will bite - this is not a complete ans but an approximation:
there are 100*99*98 ways to pick 3 different no. out of 100
if 2 of the no. picked are >10, then there is no way the third no. can be larger than the products of the other 2 nos.
there are 90*89*98 ways to pick 2 nos between 10 and 100 and a third no. between 1 and 100.
So an approximate ans = 100*99*98 - 90*89*98 = 185220 but the actual ans will be smaller than this.
15 + 2x - 4 = 9x + 11 - 7x
2x + 11 = 2x + 11
always true
2x + 3(4x - 1) = 2(5x + 3) + 4x
2x + 12x - 3 = 10x + 6 + 4x
14x - 3 = 14x + 6
never true
