Answer: they sold 31 soccer balls and 28 footballs.

Step-by-step explanation:

Let x represent the number of soccer balls that were sold.

Let y represent the number of football that were sold.

sports store sold a total of 59 footballs and soccer balls last weekend. This means that

x + y = 59

Soccer balls cost $12 and footballs costs $18. If total sales were $876, it means that

12x + 18y = 876 - - - - - - - - -- - -1

Substituting x = 59 - y into equation 1, it becomes

12(59 - y) + 18y = 876

708 - 12y + 18y = 876

- 12y + 18y = 876 - 708

6y = 168

y = 168/6

y = 28

x = 59 - y = 59 - 28

x = 31

siniylev [52]

Answer:

  A) 1/45

  B) 1/60

Step-by-step explanation:

<u>Part A</u>

The actual car has a length to width ratio of ...

  length/width = (570 cm)/(180 cm) = 57/18 = 3 1/6

The rectangle on the screen has a length to width ratio of ...

  length/width = (13 cm)/(4 cm) = 3 1/4

Relative to its width, the screen rectangle is longer than necessary for a model of the car. So, the scale factor will be determined by the width of the car relative to the width of the screen model.

For a model width of 4 cm, the scale factor is ...

  model/life-size = (4 cm)/(180 cm) = 1/45

__

<u>Part B</u>

For a model width of 3 cm, the scale factor is ...

  model/life-size = (3 cm)/(180 cm) = 1/60

When factored completely, the expression 3x2 - 9x + 6 is equivalent to
Lunna [17]
Let's see what the options look like when we multiply the expressions in brackets:

(first, i multiply both parts of the second bracked by the first part of the first bracket, and then the same with the second part of the first bracket:
<span>(1) (3x - 3)(x - 2))

3x2 +6x -3x +6// this is not correct

(2) (3x + 3)(x - 2) </span>


3x2-6x+3x-6//this is not correct

(3)

3(x + 1)(x - 2)
3(x2-2x+x-2)//simplifying:
3(x2-x-2)//multiplying:
3x2-3x-6)
- so this is not correct either
(4) 3(x - 1)(x - 2)
3(x2-2x - x + 2)
3(x2-3x +2)
3x2-9x +6 - well, here is our winner!
