Answer: I think you meant (9^3) 6
If I’m not mistaken the answer is
4374 because 9x9x9= 729x6
Answer:
3/10
Step-by-step explanation:
multiply 10k to 0.3125 and you get 3,125 but if you put it in decimal form its 3.125 (3,125 ÷ 10,000) you can round down to 3 since the numbers on the right side of the decimal does not go over 5. (Simplist Form)
Ok so we have the first portion. We need to do cross multiplication first. So that would be 20(2x - 9) and 10(9)
So
20(2x - 9)=90
40x - 180=90
Then add 180 to itself then to 90
40x=270
X=6.75
Now let’s set the next one up knowing what we know from the previous one.
18(3x + 4)= 12(15)
54x + 72=180
Subtract 72 from it’s self and 180
54x=108
X=2
Answer:
-9
Step-by-step explanation:
18÷x = -2
18 = -2×x
18 = -2x
-9 = x
x = -9
