Estelle is helping at a community food drive by boxing up cans of soup. There are two sizes of boxes, large and small. Estelle f
podryga [215]

Answer:

The small box contains 21 cans

<em></em>

Step-by-step explanation:

Represent the small box with S and the large with L.

For Estelle:

3L + 5S = 170

For the boy:

4L + 4S = 184

Required

Determine the cans in the small box

3L + 5S = 170 --- (1)

4L + 4S = 184 --- (2)

Divide (2) through by 4

L + S = 46

Make L the subject

L = 46 -S

Substitute 46 - S for L in (1)

3L + 5S = 170

3(46 - S) + 5S = 170

Open bracket

128 - 3S + 5S = 170

128 + 2S = 170

Collect Like Terms

2S = 170-128

2S = 42

Divide both sides by 2

S = 21

<em>Hence, the small box contains 21 cans</em>

Which of the points A(−6, 2), B(0, 0), C(4, −2), D(−12, 6), E(−10, 10) belong to the graph of direct variation y=− 1 2 x?
vovangra [49]

ANSWER

B(0, 0),

EXPLANATION

The given points are A(−6, 2), B(0, 0), C(4, −2), D(−12, 6), E(−10, 10).

The equation of the direction variation is

y =  - 12x

The point that belongs the graph of the direct variation must satisfy the variation equation.

Note that the graph of direct variation equation passes through the origin therefore the point (0,0) satisfies it.

0=-12(0)

0=0

This is true

The other points do not satisfy this variation equation, hence they do not lie on its graph
