-6(p+8)=36

Algebra two step equation

The value of p = -14

Step-by-step explanation:

Given the equation

Divide both sides by -6

simplify

Subtract 8 from both sides

simplify

Therefore,

The value of p = -14

$20.5

Step-by-step explanation:

Let x  denotes the amount for total bill.

We are given that ,  Sierra left $4.50 as a tip for a waiter.

This was 18% of the bill before the tip.

We can write 18% = 0.18. [To convert percent into decimal we divide it by 100.]

Then, the tip amount = 0.18 x Total bill

So, the total bill amount = $25

Hence, her total bill before the tip= Total bill amount - Tip amount

= $25- $4.50=$20.5

Thus ,her total bill before the tip= $20.5
