So, bike=b and accessories=a.
b+a=320
Since the bike is worth 7 times more than the accessories, the b would turn into 7a (because 7 times the cost of accessories is the cost of the bike).
The equation would now turn into 7a+a=320.
Solve for a.
7a+a=320
8a=320
a=40
Now that you know the cost of the accessories, you multiply that 40
by 7 to get the cost of the bike.
40(7)
280
The cost of the bike is $280.
The cost of the accessories are/is $40.
The answer is D hope this helps :]
24 girls divided by 6 girls = 4 boys. 3 boys for every girl and there is 6 girls so you would do 4 x 3 = 12 boys.
Volume = (1/3) * base area * height
= 1/3 * 24 * 18
= 144 ft^3
233 1/3
you start with .3x = 70, as this is the sentence given, solving for x.
divide both sides by .3, and you get x
