In most linear programming problems, there are two stages:

Answer: Bruno = 16 cans, Blaze = 14 cans

Step-by-step explanation:

Part A gave you the three equations.

Part B showed you the intersected points --> (16, 14), (20, 10), & (21.4, 10.7)

Part C is giving you the Cost function: C(x, y) =0.10x + 0.20y

Input the intersected points into the Cost function to find the maximum.

C(16,14) = 0.10(16) + 0.20(14)

= 1.60 + 2.80

= 4.40

C(20,10) = 0.10(20) + 0.20(10)

= 2.0 + 2.00

= 4.00

C(21.4,10.7) = 0.10(21.4) + 0.20(10.7)

= 2.14 + 2.14

= 4.28

Of the three results we just found, 4.40 is the biggest value.

So, the maximum occurs at C(16,14) = 4.40

Two angle that form a linear pair are supplementary meaning they add to equal 180° (straight line).

make the bigger angle = x
then smaller angle = x - 30°

x + x - 30 = 180
2x - 30 = 180
2x = 180 + 30
2x = 210
x = 210/2
x = 105

The question is to find the smaller angle which was: x - 30

105 - 30 = 75°

Jenna made money babysitting, and she also earned $20 cleaning her neighbor's basement. During the week, her total earnings were

Firlakuza [10]

Answer:

Jenna spent 7 hours babysitting.

Step-by-step explanation:

With the information provided, you can say that Jenna's total earnings are equal to the amount she earned cleaning her neighbor's basement plus the result of multiplying the charge per hour for babysitting for the number f hours, which is:

e=20+5x, where:

e represents the total earnings

x is the number of hours

Now, you can replace e with 55 that is the toal amount she earned and solve for x:

55=20+5x

55-20=5x

35=5x

x=35/5

x=7

According to this, the answer is that Jenna spent 7 hours babysitting.
