Answer:
ties cost $3
shirts cost $15
Step-by-step explanation:
s=shirts
t = ties
3 shirts and 5 ties cost $60:
3s+5t=60
2 shirts and 3 ties cost $39:
2s+3t=39
−2(3s+5t=60)
3(2s+3t=39)
−6s−10t=−120
6s+9t=117
add equations together:
−t = −3
t = 3
so ties cost $3, use either of the original equations to solve the price of shirts:
2s+3⋅(3)=392
s+9=392s=30
s=15
so shirts cost $15
The area of a parallelogram is base * hight.
Choice A: base = 10 & hight = 12,
so area = 10*12 = 120
Choice B: base = 10 & hight = 6,
so Area = 10*6 = 60
To practice, try to find the area for choice c & d.
If your still having trouble, search Google for "how to find area of a parallelogram".
The sales tax is $7.67
In total, with the sales tax, the phone would be $92.65
46 because 8-3 equals 5 then 5 times 5 equals 25 to then add 11 to finally subtract 66-20 which equals 46
