C. Apply the distributive property to get 4x-12=9.
Step-by-step explanation:
To get x out of the parentheses, you have to use the distributive property by multiplying both x and -3.
Hope this helps you :)
Answer:
x = 269/15
Step-by-step explanation:
(3x - 5) / 6 - (4 + x) / 7 = 5
7(3x - 5) - 6(4 + x) = 5(42)
21x - 35 - 24 - 6x = 210
15x - 59 = 210
15x = 269
x = 269/15
There are a total of 16 coins, so out of the ratio, that 16 goes on the bottom. Now you have to add up the coins that are NOT quarters and that number goes on the top. So your ratio is 8/16 or 1/2
The only rule to follow is
Divide dividend by divisor and the mention the quotient and things left after remains in place of remainder
Here is a sample

Answer:
Q3: A
Q4: 9x² + (-x) + (-3)
Step-by-step explanation:
Q3: C (63) => x = 63. => C(x) = 36 x 63
Q4: f(x) + g(x) = 7x² - 5x + 3 + 2x² + 4x - 6 = (7x² + 2x²) + (-5x + 4x) + (3 - 6) = 9x² + (-x) + (-3)
