Astore sells cooking oil of two different brands in bottles of the same size. the table below and the equation each show the price (y), in dollars, of different number of bottles of oil (x):
brand a
number of bottles, x price (dollars), y
2
26
3
39
4
52
5
65
brand b
y = 16x
how many dollars more is the price of 7 bottles of brand b oil than the price of 7 bottles of brand a oil?
$3
$10
$21
$29

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

-2/

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )
