Use the table to work out the values of a , b , c , and d .​
scZoUnD [109]

Answer:

a = - 1, b = - 3, c = - 5, d = - 6

Step-by-step explanation:

Substitute the appropriate values of x into the equation and evaluate

x = - 3 : y = - (- 3) - 4 = 3 - 4 = - 1 → a

x = - 1 : y = - (- 1) - 4 = 1 - 4 = - 3 → b

x = 1 : y = - 1 - 4 = - 5 → c

x = 2 : y = - 2 - 4 = - 6 → d

A retailer allowed 12% discount and sold a T-shirt at a loss of Rs 16. If he had sold it at 10% discount he would have gained Rs
Murrr4er [49]

Answer: Marked Prixe = Rs. 1800

Step-by-step explanation:

Let the marked price be M

1) A retailer allowed 12% discount and sold a T-shirt at a loss of Rs 16.

SP = 0.88M

CP - SP = 16

CP = 16 + SP

CP = 16 + 0.88M

2) If he had sold it at 10% discount he would have gained Rs 20.

SP = 0.9M

SP - CP = 20

0.9M = 20 + CP

CP = 0.9M - 20

16 + 0.88M = 0.9M - 20

0.9M - 0.88M = 20+16

0.02M = 36

36 = 0.02M

M = 1800

The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28. A table with 6 columns and 2 rows. T
Alexus [3.1K]

The solution is (5,2)

Step-by-step explanation:

From the third column the equation for sum of equivalent system is given as;

8x = 40

divide both sides by 8 to get value of x

8x/8 = 40/8

x=5

Using the value of x in the fifth column's first equation will be;

4x +4y =28

4(5) + 4y =28

20 +4y =28

4y= 28-20

4y=8

divide both sides by 4 to get y

4y/4 =8/4

y=2

The solution is x=5 and y=2 written as (5,2)

Create and solve an appropriate equation:  Maria's earnings = Liam's earnings

                                                                       0.20x                 = $625+0.10x.

Find x.

0.10x = $625; thus, x = $6250.  At this level of food sales, these two people earn the same amount.
