Simora [160]3 years ago

Answer:

x=-121

Step-by-step explanation:

.4(5+2x) -12 = .9x+2.1

Distribute the .4

2 + .8x -12 = .9x+2.1

Combine like terms

-10 +.8x = .9x +2.1

Subtract .8x from each side

-10 +.8x-.8x = .9x-.8x +2.1

-10 = .1x +2.1

Subtract 2.1 from each side

-10-2.1 = .1x +2.1-2.1

-12.1 = .1x

Divide by .1

-12.1/.1 = 1.x/.1

-121 =x

A privately owned lake contains two types of game fish, bass and trout. The owner provides two types of food, A and B, for these
Vinvika [58]

Answer:

133 fishes

Step-by-step explanation:

Units of food A = 400 units

Units of food B = 400 units

Fish Bass required 2 units of A and 4 units of B.

Fish Trout requires 5 units of A and 2 units of B.

i. For food A,

total units of food A required = 2 + 5

                                                 = 7 units

number of bass and trout that would consume food A = 2 x \frac{400}{7}

                                               = 114.3

number of bass and trout that would consume food A = 114

ii. For food B,

total units of food B required = 4 + 2

                                                = 6 units

number of bass and trout that would consume food B = 2 x \frac{400}{6}

                                                 = 133.3

number of bass and trout that would consume food B = 133

Thus, the maximum number of fish that the lake can support is 133.

Well based on this information, I don't think that this is a valid inference. There isn't enough data to go off of in order to answer this question.
