Answer:
x=16
Step-by-step explanation:
1. Simplify 9/12 to 3/4.
2. Multiply both sides by x.
3. Simplify 3/4x to 3x/4
4. Multiply both sides by 4.

7. Simplify 48/3 to 16.
Answer:
2, 4, 5, and 6 have the same pair of solutions.
Step-by-step explanation:
1. n(n+3)(n-4) = 0
2. 2n(4n+6)(6n-4) = 0
3. 2n(6-4n)(4n-6n) = 0
4. n(2n+3)(3n-2) = 0
5. 2n(2n+3)(3n-2) = 0
6. 3n(6n+9)(9n-6) = 0
Answers:
1. n = 0, -3, 4
2. n = 0, -3/2, 2/3
3. n = 0, 3/2
4. n = 0, -3/2, 2/3
5. n = 0, -3/2, 2/3
6. n = 0, -3/2, 2/3
Answer:
4 layers with <u><em>$2.84</em></u><em> </em>left over
Step-by-step explanation:
You start off with the cost of the cake which is <em>$12.96</em>, then add<em> $3.55</em> (in this case 4 times) until you get the closest number to <em>$30</em> without going over (<em>$27.16</em>) . You find the amount of money that is left over by subtracting you original amount <em>($30)</em> with the amount you spent total on the cake <em>($27.16) .</em>
