Answer:
211 cm
Step-by-step explanation:
upper rectangle + lower rectangle (11-8=3) + end triangles
(8x20) + (3x12) + (1/2x3x5 each x2)
160+36+15=211
Answer:
-9.5 is larger by 2 units

-9.5 - (-11.5)
= -9.5 + 11.5
= 2.
Answer:
165.628° (The 8 has a line over it signalizing that it repeats forever, but I didn't know how to put it in.)
Step-by-step explanation:
Since 165 is whole number, it is a full degree. Since each minute is equal to 1/60 degrees, you need to multiply 37 by 1/60. Since each second is equal to 1/3600 degrees, multiply it 1/3600 by 44. Add them all together.
165 + 37 x 1/60 + 44 x 1/3600
simplify: 74533/450
Convert the fraction into a decimal by dividing the numerator by the denominator and you get 165.628° (with a repeating 8).

</span>Okay so "0.9x-1.3=-3.1" x=-2
<span><span><span>0.9x</span>−1.3</span>=<span>−3.1
</span></span>add 1.3 to both sides
<span><span><span><span>0.9x</span>−1.3</span>+1.3</span>=<span><span>−3.1</span>+1.3
</span></span><span><span>0.9x</span>=<span>−1.8
</span></span>divide both sides by 0.9
<span><span><span>0.9x/</span>0.9</span>=<span><span>−1.8/</span><span>0.9
</span></span></span>x=<span>−2</span>
So if you plug in -2 into "x-0.8" you get −2.8
<span>=<span><span>−2</span>−0.8
</span></span><span>=<span><span>−2-</span><span>0.8
</span></span></span><span>=<span>−2.8
</span></span>Hope this helps.
