Answer:

7 hamsters at 5 pesos each and 13 hamsters at 8 pesos each

Step-by-step explanation:

5x + 8y = 139

x + y = 20

x = 20 - y

5x + 8y = 139

5(20 - y) + 8y = 139

100 - 5y + 8y = 139

100 + 3y = 139

3y = 139 - 100

3y = 39

3y/3 = 39/3

y = 13

x + y = 20

x + 13 = 20

x = 20 - 13

x = 7

Is the value of the variables used in this metric system?
Marat540 [252]

Solution:

a=-2 b=1 c=4 d=0

Analysis:

When we multiply a matrix by a constant, we multiply each term of the matrix by the constant.

In this case, as we need to find the value of the initial matrix, we can divide each term of the matrix by the constant. In this case, let´s divide by -5

So, it would be:

a=10/-5 a=-2

b=-5/-5 b=1

c=-20/-5 c=4

d=0/-5 d=0
