Suppose that an economy has three industries (fishing, agriculture, and mining), and that matrix a is the technology matrix for this economy. f a m " # 0.5 0.2 0.2 fishing 0.3 0.5 0.2 agriculture 0.1 0.4 0.3 mining if surpluses of 180 units of fishing output, 90 units each of agricultural and mining goods are desired, find the gross production of each industry.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

no solution

step-by-step explanation:

there is not enough information in the problem to solve.
