Question

Evaluate 1/4c + 3d when c = 6 and d = 7

please don't just give me the answer, explainnn because i don't know how to do this​

Answer 1

Answer as a decimal = 22.5

Answer as a fraction = 45/2

===========================================================

Step-by-step explanation:

Replace c with 6, and replace d with 7.

Then use the order of operations (PEMDAS) to simplify until you get a single number.

`(1)/(4)c + 3d\\\\(1)/(4)(6) + 3(7)\\\\(6)/(4) + 21\\\\1.5 + 21\\\\22.5\\\\`

If you want to convert this to an improper fraction, then,

`22.5 = 22 + 0.5\\\\22.5 = 22 + (1)/(2)\\\\22.5 = 22*(2)/(2) + (1)/(2)\\\\22.5 = (44)/(2) + (1)/(2)\\\\22.5 = (44+1)/(2)\\\\22.5 = (45)/(2)\\\\`

Answer 2

22 1/2

Step-by-step explanation:

1/4×6=1 1/2

3×7=21

21+1 1/2=22 1/2
