I think it's B my dude
925-400=525
525/8=65.625
65.625*100= $6,562.50
Answer:a=3/4
b=3/4
Step-by-step explanation:
3a+5b=6
9a+7b=12
-3(3a+5b)=-3(6)
9a+7b=12
-9a-15b=-18
9a+7b=12
-8b=-6
b=3/4
3a+5(3/4)=6
3a+15/4=6
3a=9/4
a=3/4

have a nice day !!!
Answer:
C 14n - 8
Step-by-step explanation:
area of rectangle = length × width = 12n² - 19n - 21
width = 3n - 7
so, what do we need to multiply with width to get the expression of the area ?
4n + 3
(because we think, what do we need to multiply 3n with to get 12n², and what to multiply -7 to get -21)
control : (3n-7)×(4n+3) = 12n²-28n+9n-21 = 12n²-19n-21
perimeter is now 2× length + 2× width
p = 2(3n-7) + 2(4n+3) = 6n - 14 + 8n + 6 = 14n - 8
Answer:
d. median of 1999 data
Step-by-step explanation:
a=10,249.25 (add all the 1998 data then divide by 4)
b=619 (add all 1999 data then divide by 4)
c= 2568 10050 12047 16332
10050+12047/2
d=3026 9904 13063 16546
9904+13063/2
