Alejandra spent her birthday money on a video game that cost 24$,a controller for 13$,and a memory card for 16$ . The total tax
natita [175]

Answer: Alejandra gave $60 to the cashier.

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given.

We have to subtract to the amount that Alejandra paid(x) the sum of the costs of each product [videogame (24), controller (13) and memory card (169] and the total tax (3). the expression must be equal to the amount received in change.

Mathematically speaking:

x -(24+13+16+3) = 4

Solving for x:

x - 56 =4

x = 4+56

x =60

Alejandra gave $60 to the cashier.

Feel free to ask for more if needed or if you did not understand something.

Plz I need some help with 11-12 . My teacher didn’t even explain it correctly so now I’m confused.
rusak2 [61]

Answer:

Step 1: Transpose everything to one side

12. x²+16x+15-10x+4=0

Step 2: Add the like terms

x² + (16x - 10x) + 15 + 4=0

x² + 6x + 19=0

Step 3: Use the quadratic formula to get the value(s) of x.

a=1 b=6 c=19

x =  \frac{ - b +  -  \sqrt{b {}^{2} - 4ac }  {}^{} }{2a}

therefore, x=... or x
