Someone plz help me 1-1\2c=6

1 - 1/2c = 6

1 -1 - 1/2c = 6 -1 (subtract 1 on both sides)

-1/2c = 5 (next do the inverse operation)

c = 5 ÷ 1/2

c = -10

to check your answer substitute the value of c in the equation;

1- 1/2c = 6

1- 1/2(-10) = 6

1 + 5 = 6

6 =6

6(y+4)^2-5=49 a). y = -2 or y = -6 b). y = -1 or y = -7 c). y = 0 or y = -4 d). NO REAL SOLUTIONS

☾Let's solve this problem Step-By-Step!
☾Question you asked:
6(y+4)^2−5=49

Simplify both sides of the equation:
6y^2+48y+91=49

Subtract 49 from both sides:
6y^2+48y+9149=49−49
6y^2+48y+42=0

Factor left side of equation:
6(y+1)(y+7)=0

Set factors equal to 0:
y+1=0 or y+7=0

☾Your answer is: 
y=1 or y=−7

Ok just remember that the minus sign before the (9ab-5) is like a minus 1 so it changes the sign inside the bracket...
>>5ab-4a-8-9ab+5

25% of what number is 41?

Let us assume the number = x
Then
(25/100) * x = 41
25x = 4100
x = 4100/25
   = 164
so the unknown number comes out to be 64, This is one of the simplest way to clearly get to the solution that is required. I hope the procedure is clear enough for you to understand. Only while deducing the result, be careful about the calculation part.In future you can always use this procedure for finding the solutions to similar problems.
