R-9s=2 add 9s to both sides
r=2+9s making 3r-3s=-10 become:
3(2+9s)-3s=-10 perform indicated multiplication on left side
6+27s-3s=-10 combine like terms on left side
6+24s=-10 subtract 6 from both sides
24s=-16 divide both sides by 24
s=-16/24
s=-2/3, making r-9s=2 become:
r-9(-2/3)=2 perform indicated multiplication on left side
r+6=2 subtract 6 from both sides
r=-4
So s= -2/3 and r= -4
$8792 / $14 = 628 tickets were sold
I think the answer would be 112cm.
To find the area of the triangle you need to do basexheight divided by 2.
8x10 divided by 2 = 40
To find the area of the rectangle
12x6=72
40+72= 112cm
I’m not sure if it’s right but I hope this helps.
204
71:35=2
2 goes on the top
2x35=70
71-70=1
then carry them down 14
14:35=0
Carry it up it should be 20 up there now
Carry the 0 from the 7140 down to make it 140
140:35=4
Then carry that 4 up and your answer is 204
√8 = 2√2 = 2√2 = 2 x 1.414... =2.828....(irrational number between 2 and 3)
2.π = 6.283...........................................(irrational number between 6 and 7)
7/3 = 2.33333.. (mind you a repeating decimal is a rational number), then:
7/3 = 2.33333 ......................................(rational number between 2 and 3)
e/2 = 1.359...........................................(irrational number between 1 and 2)
3/2 = 1.5 ..............................................(rational number between 1 and 2)
