By substituting the numbers into its own variable of t and f, the equation should now be 9(21)+(3*3)*21+12. This simplifies to 189+(9*21)+12 --> 189 +189 +12, which equals 390.
Answer:
The Correct answer is: 1/3
Step-by-step explanation:
x = 2, y = 3
(4x + 1) / 3y²
(4*2 + 1) / 3*3²
(8 + 1) / (3*9)
9 / 27
= 1/3
Answer:
The Answer is: the Number is -2
Step-by-step explanation:
Let n = the number.
Five times the number minus 10 is less than 6 times the number minus eight:
5n - 10 = 6n - 8
-1n = -8 + 10
-n = 2
n = -2, the value of the number is -2.
Proof:
5(-2) - 10 = 6(-2) - 8
-10 - 10 = -12 - 8
-20 = -20
