Answer:
2/5
Step-by-step explanation:
slope is the "inclination" of a line, so to be parallel they must have the same slope
direct variation
y = kx
substitute in and solve for k
14 = k(-4)
14/-4 =k
k = -7/2
y = -7/2 x
y = -7/2 * -6
y = 42/2 = 21
Choice D
The soda was $1.00.
Hot Dog- $3.50
Peanuts- $4.00
3.50+4.00= 7.50
Total paid is $11.50-$7.50= $4.00-$3.00(coupon)= $1.00
Answer:
3/10 of the aquarium are yellow tangs.
Step-by-step explanation:
Given that in an aquarium 2/5 of the fish or surgeonfish and of these, 3/4 are yellow tangs, to determine what fraction of all fish in the aquarium are yellow tangs the following calculation must be performed:
2/5 = 0.40
0.40 x 3/4 = X
1.20 / 4 = X
0.30 = X
0.30 = 3/10
Therefore 3/10 of the aquarium are yellow tangs.
