Hello.
30% of $400 is $120. You can find this by multiplying .30 by 400.
Am not sure but i think its 9m^4-49n^6 hope it helps :)
Answer:
Step-by-step explanation:
A) for this we want to solve for x
we first have to ditribute 2 to 9x-6 and 6 to 3x-2
18x - 12 = 18x -12 + 2 --> 18x - 12 = 18x - 10
add ten to both sides 18x -12 (+10) = 18x
18x - 2 = 18x since you can solve it theirs no solution
B) you combind like terms --> 4x + 8 = 4x + 8
since their the same on both sides that means they have infinante solutions
Easy this answer is going to be 0.517 you can read and round
