Answer:
-3/2
Step-by-step explanation:
Here we have an ambiguous notation. Hence, I assume you mean (-12/((3 x (-8+ (-4)^2 -6) +2), which is the one that makes more sense.
First, we work the arithmetic on the denominator (D).
D= 3 x (-8 + (-4)^2 - 6) + 2
D=3 x (-8 + (-4) x (-4) -6) + 2
D= 3x (-8 +16 -6) + 2
D= 3 x (2) + 2=6 + 2=8
Now, we just have to divide -12 by D to obtain the answer.
-12/D = -12/8 =(-2 x 2 x 3)/(2 x 2 x 2) = -3/2

Answer:
Distance = 500 miles
Step-by-step explanation:
<u>Step 1: Write the data of speed, distance and time for aeroplane and automobile.</u>
<em>Automobile:</em>
Speed = r
Time = 10 hours (3 am till 1 pm)
Distance = SxT
Distance = r x 10 = 10r
<em>Aeroplane:</em>
Speed = 200 + r (200 mph more than automobile)
Time = 2 hours ( 11 am till 1 pm)
Distance = SxT
Distance = 2x(200+r) = 400+2r
<u>Step 2: Equate both distances to find the value of r</u>
Distance of automobile = Distance of aeroplane
10r = 400 + 2r
8r = 400
r = 50
<u>Step 3: Find the distance using any one equation</u>
Distance of automobile = 10r
r = 50
Distance = 10 x 50 = 500 miles
Therefore, the plane travels 500 miles.

150 is the correct answer! Please mark brainliest
1cg=10mg, so 90cg95mg=90*10+95=995 mg. 7g=7*1000=7000mg, 12cg=12*10=120mg, so 7g 12 cg 18 mg =7000+120+18=7138mg, so <span>90 cg 95 mg + 7g 12 cg 18 mg=14138mg=14000mg+100mg+38mg=14g1cg38mg.</span>
