To solve the system, the best way to do it is by eliminatiion.  Multiply the first equation by -2 and the second equation by 3.  This changes the system to -6x-4y= -73 and 6x+15y= 150.  When you add those together, the x's are eliminated, leaving 11y = 77 and y = 7.  Sub that in to any one of the above equations to solve for x.  6x + 15(77) = 150 and 6x + 105 = 150.  6x = 45 and x=7.5.  If x is the library and y is the coffee cart, then he makes more at the library.  Your choices aren't numbered, but it's the third one.

Salsk061 [2.6K]
The dollar amount of merchandise inventory is A. $28,800
Let N = be the missing number
1.) 
N/$45,000 = 2.65/1 (cross multiply to get the current assets)
                   N = $119,250
2.) N/$45,000 = 2.01 (cross multiply to get current the quick assets)
                   N = $90,450
3.) Since there are no prepaid expenses, subtract current quick assets from the current assets to get the merchandise inventory
$119,250 - $90,450 = $28,800

PLS HELP.... If 4x^2 + bx + 9 = 0, where b is the constant, has exactly one solution, what is a possible value of b ?
IgorLugansk [536]
You can use the discriminant rule, which is :
b^2 -4ac
“exactly one solution” means that it is equal to zero
so:
b^2 -4(4)(9)=0
b^2 -4(36)=0
b^2 -144=0
b^2=144
square root both sides
b=12 or -12

hope this helps !
