Answer:
(46 , -17)
Step-by-step explanation:
hello :
x + y = 29...(*)
x + 2y = 12 ...(**)
multiply (*) by -1 : -x-y=-29 ...(***)
add (**) and(***) : y=-17
put this value in (*) : x-17 =29
so : x=46
one solution : (46 , -17)
<span>A)
2x+2(x-6)=64
4x-12=64
4x=76
x=19
x-6=13
B)
20+4x+x=180
5x=160
x=32 degrees
4x=128 degrees
C)
180-62.5=117.5 degrees</span>

Answer: $13.77
Step-by-step explanation:
To get the final price for the screen protectors, we have to calculate the value of the tax and add to the current price of the screen protector.
The sales tax will be:
= 6% × $12.99
= 6/100 × $12.99
= 0.06 × $12.99
= $0.7794
The price of the screen protector will now be:
= $12.99 + $0.7794
= $13.7694
= $13.77
