Step-by-step explanation: First the solution: (Start form the end!!) $40.00 (the ending total) minus the $10.00 he added on, $40-$10=$30 which is half of the original total so now you have to multiply by two to get the starting balance ($60.00)!

Now for the inequality, since we don't know the beginning balance of the gift card that will be our variable.

Then, since he spent half of this buying coffee we would have to split our variable in half.

g/2

After that, Peter added an additional $10.00 to said gift card.

g/2 + 10 = 40

Going off of that the final inequality would be $60.00 = g/2 + 10 = 40

BAMM!! GOOD LUCK IN MATH CLASS!!!

What is the value of tan x°?

dmitriy555 [2]

Hi there!

$\tan(x) = \frac{opposite \: side}{adjecent \: side}$
$\tan(x) = \frac{8}{6}$
$\tan(x) = 1 \frac{1}{3}$

$x = 53.1$
Therefore tan x° = 1 1/3 and x = 53.1°
