You have $32 to spend at the music store. Each cassette tape costs $5 and each CD costs $9. what is a linear inequality that rep

tigry1 [53]

you have $32

you can't spend more than that but you can spend less if you want, or you can spend exactly the amount you have.

the total cost will depend on how many cassettes you buy and how many CDs you buy

knowing this information, you can set up the inequality:

32 ≥ 5x + 9y

hope this helped

The length and breadth of a rectangle are in the ratio 3:2 respectively. If the sides of the rectangle are increased by 1 meter

Aleks04 [339]

<u>ANSWER: </u>

The length and breadth of the rectangle are 18 m and 12 m.

<u>SOLUTION: </u>

Let the length and breadth of a rectangle be "l" and "b"

Given,length and breadth of the rectangle are in ratio 3 : 2

Then, length : breadth :: 3 : 2

$\begin{array}{l}{\frac{l}{b}=\frac{3}{2}} \\\\ {l=\frac{3 b}{2}}\end{array}$ -- eqn 1

After changing the length and breadth by 1 meter on both sides, length and breadth becomes L+2 and b+2

Now, the ratio of length to breadth is 10 : 7

Length : breadth :: 10 : 7

$\frac{l+2}{b+2}=\frac{10}{7}$

$(l +2 ) \times 7 = 10 \times ( b + 2)$

7l + 14 = 10b + 20

10b – 7l + 20 -14 = 0

10b – 7l + 6 =0 -- eqn (2)

Now, substitute “l” value in (2)

$10 b-7\left(\frac{3 b}{2}\right)+6=0$

$10 b-\frac{21 b}{2}+6=0$

20b – 21b + 12 = 0

-b + 12 = 0

b = 12.

Substitute b value in (2)

10(12) – 7l + 6 = 0

120 + 6 = 7l

7l = 126

l = 18

hence, the length and breadth of the rectangle are 18 m and 12 m.

Which of the following ordered pairs is a solution of 3x+2y=-19

34kurt

We need the ordered pairs to choose an answer, but if you want to do it yourself you plug in the x and y values (x,y) and test to see if the equation is true, and equals -19.

Estimate the length of one side of a square floor if the area is 320 square feet. Round to the nearest whole number.

igomit [66]

So if the area of a square is 320 square meters, then because all four sides are equal, you would end up with the equation $x^{2}=320$ which simplifies to
