Answer:
the answer is A
Step-by-step explanation:
y is the total and 48 is the minutes
x is the number of hours,
so when you multiply x by 48, you get
the total, which is y
Idk if it helps but i tried :/ C:
There are several ways to solve this, but the law of sines is probably the easiest...
Law of Sines: sina/A=sinb/B=sinc/C for any triangle...in this case we can say:
sin48/x=sin90/55
xsin90=55sin48
x=55sin48/sin90
x≈40.873 (to nearest one-thousandth, not sure which precision you needed)
Decreased by 25%
find 25% of 12 and decrease 12 by it
percent means parts out of 100
25%=25/100=1/4
'of' means multiply
25% of 12=1/4 times 12=3
decrease 12 by 3
12-3=9
answer is 9
0 solution
3(x+4)=3x+4
3x+12=3x+4
(3x-3x)=(-12+4)
0=-8
so no posible solution
