Step-by-step explanation:
x = number of small boxes
y = number of large boxes
these equations model the situation :
x + y = 8
12x + 45y = 195
FYI - the solution :
from the first equation we get
x = 8 - y
we use that in the second equation
12(8 - y) + 45y = 195
96 - 12y + 45y = 195
33y = 99
y = 3
x = 8 - y = 8 - 3 = 5
Hello :
the general term is : an = a1×r^(n-1)
a1 : the first term....( a1 = 6)
r : the common ratio......( r = -1/3 )
when : n = 8 a8 is the eighth term : a8 = 6×(-1/3)^7
a8 =- 6×(1/3)^7 because : (-1/3)^7 = - (1/3)^7
a8 = -2 ×(3/3^7)
a8 = -2×(1/3^6)
a8 = (-2)/[ 3^6 ]
<span>7m + 2/8 = 2m - 1/3
(7m X 24) + (2/8 X 24) = (2m X 24) - (1/3 X 24)
168m + 6 = 48m - 8
120m = -14
m = -0.1166</span>
Answer:
C. c = 8
Step-by-step explanation:
Step 1: Write equation
7 - 3c = -17
Step 2: Subtract 7 on both sides
-3c = -24
Step 3: Divide both sides by -3
c = 8
