(1)/(4)c+3d when 
c=6 and 
d=7.

Evaluate 14c+3d \frac{1}{4} c+3 d when c=6 c=6 and d=7 d=7 .

Full solution

Q. Evaluate 14c+3d \frac{1}{4} c+3 d when c=6 c=6 and d=7 d=7 .
  1. Substitute values: Substitute the given values of cc and dd into the expression.\newlineWe have the expression (14)c+3d(\frac{1}{4})c + 3d and we are given c=6c = 6 and d=7d = 7. Let's substitute these values into the expression.\newline(14)(6)+3(7)(\frac{1}{4})(6) + 3(7)
  2. Perform multiplication: Perform the multiplication for each term.\newlineNow we multiply the numbers in each term.\newline(1/4)×6=1.5(1/4)\times 6 = 1.5\newline3×7=213\times 7 = 21
  3. Add results: Add the results of the multiplications.\newlineNext, we add the results from Step 22 together.\newline1.5+21=22.51.5 + 21 = 22.5
