riadik2000 [5.3K]

Answer:

The cost for 1 chair is $2.75 and the cost for 1 table is $8.75

Step-by-step explanation:

Use the elimination method of linear equations to find your answer.

Our equations for this problem are:

3c+5t=52 and 9c+7t=86

1. Multiply the entire first equation by -3.

-3(3c+5t=52)

2. Simplify the equation from above:

-9c-15t=-156

3. Stack the two equations on top of each other and add/subtract:

-9c-15t=-156

9c+7t=86

4. You should be left with -8t=-70. Simplify this to find the value of t:

t=8.75

5. Plug the value of t into any of the original equations and solve for c.

3c+5(8.75)=52

6. Simplify the equation above:

3c+43.75=52

7. Subtract 43.75 from both sides of the equation:

3c=8.25

8. Divide both sides by 3 to get your c value:

c=2.75

Each side of a rhombus is 20 cm long and one of its diagonals is 24 cm in length, find the area of this rhombus?

vodomira [7]

Answer:

AB = 20 CM

OA = 1

__ × 24 cm

= 12 cm

AOB = 90 °

OB² == AB² - OA ²

$( {20}^{2} ) - ( {12}^{2} ) \\ = 400 - 144 \\ = 256 \\$

$ob \: = \sqrt{256} = 16 \\ bd \: = 2 \times ob \\ = 2 \times 16 \\ = 32cm \: \\$

AREA OF ABCD IS

$\frac{1}{2 } \times ac \times bd \\ = \frac{1}{2} \times 24 \times 32 \\ 384cm$

$hope \: its \: helpful \: \: to \: you \:$
