Answer:

$\frac{P}{A+P}\geqslant 0.6$

Step-by-step explanation:

Amount of money to invest in Atlantic Oil= A

Amount of money to invest in Pacific Oil = P

Total money invested in the two oil companies = A+P

Since at least 60% of the money invested in the two oil companies must be in Pacific Oil

$\frac{P}{A+P} \times 100\geqslant 60$

$\Rightarrow \frac{P}{A+P} \geqslant \frac{60}{100}$

$\Rightarrow$ $\frac{P}{A+P}\geqslant 0.6$

Hence the required model is $\frac{P}{A+P}\geqslant 0.6$

Sedbober [7]

Answer:the length of line segment AC is 14

Step-by-step explanation:

The diagram is shown in the attached photo

Since Angle A B C and B C A are congruent. It means that they are equal. An isosceles triangle is a triangle that has two equal sides and two equal base angles. Since Angle A B C and B C A are equal, it means that the triangle is an isosceles triangle. It also means that sides AC and AB are equal. The expression becomes

3x - 7 = 2x

3x - 2x = 7

x =7

To determine the length of line segment AC. We will substitute x = 7 into 3x - 7. It becomes

3×7 - 7 = 21 - 7 = 14
