A pound of chocolate costs 8 dollars. Kala buys p pounds. Write an equation to represent the total cost c that Kala pays.
ASHA 777 [7]

Answer:

8p=c

Step-by-step explanation:

For questions like this, it isn't asking for a numerical answer or anything complicated. It's mainly just using common sense and figuring out what you would do if you had actual numbers instead of variables. You would multiply the amount of pounds (p) by the cost per pound of $8, and that would be your answer (c). I hope I could help.

Verify if 1/2x-2 and g(x) = 2x + 4 are inverses
Triss [41]
They are inverses if f( (g(x)) = x

f((g(x)) =  (1/2) (2x + 4) - 2  = x + 2 - 2 = x

so this proves that g(x) is the inverse of f(x)

the other inverse g((f(x))  should also be = x

How can I solve this? 10+x = 5(1/5x + 2)
pshichka [43]
You use PEMDAS. Start by distributing the terms in the parentheses. The isolate the variables. To do that you subtract x from one side of the equation to the other side. You always do the other operation. If it is adding you subtract, if your multiplying your dividing and the other way around. Then you subtract 10 from each side. This equation has many solution because all the terms cancel out.
