Answer:
n = -1
Step-by-step explanation:
you've accidently substracted 6n from 12n when you were supposed to be adding them. (-6n becomes +6n when brought to the otherside of the equal sign)
Answer:
The height of the cone is 0.5
Step-by-step explanation:
The formula of a cone is:
V= 1/3 πr² h
where r = 4 inches
V = 8 cubic inches
Now plug the values in the formula:
8 = 1/3 * 3.14 *(4)^2 *h
8 = 1/3 * 3.14 * 16 *h
8 = 50.24/3 * h
Now shift the R.H.S to the L.H.S
8 * 3/50.24 =h
24/50.24 = h
0.477707 =h
Rounding off to the nearest tenths place
=0.48
=0.5
Thus the height of the cone is 0.5 ...
1. distribute the 3 into the variable and number in the equation
to do this..
2. multiply 3 by x (obtain the answer of 3x)
3. multiply 3 by -2 (obtain the answer of -6)
4. you now have the equation of ‘14 = 3x-6+5’
5. subtract 6 from 5 (obtain the answer of -1)
6. you now have the equation of ‘14 = 3x-1’
7. add one to both sides (cancel out the negative one and make the opposite side of the equation 15 instead of 14)
8. you now have the equation of ‘15 = 3x’
9. divide both sides by 3 (15 and x)
FINAL ANSWER
x = 5
