Question

Write in another form 6(a+5-1/2 c)

Answer 1

You just need to distribute (multiply everything in the parenthesis by 6)
6 × a = 6a
6 × 5 = 30
6 × 1/2 = 3
The answer would be 6a + 30 - 3c

Answer 2

six times in parentheses the variable a plus five minus one divided by two times the variable c.
