a) Keith's car will have less gas.

Locate the point in which miles driven = 90 (Between 60 and 120)

Since Keith's line is lower than Carmen, he has less gas.

We can also find the difference: 11 - 10 = 1.

It will have 1 less gallon.

b) Look at the point in which both lines meet. This means that they have the same amount of gallons remaining (8) at 180 miles driven.

Before 180 miles, Keith's car will always have less car remaining.

A local fish market is selling fish and lobsters by the pound. The fish, f, costs $4.25 a pound, while the lobster, l, costs $9.

Answer:

7 pounds of fish
18.5 pounds of lobster

Step-by-step explanation:

Let x represent the number of pounds of lobster sold. Then 25.5-x is the number of pounds of fish. The total money made is ...

4.25(25.5-x) +9.00x = 196.25

4.75x + 108.375 = 196.25 . . . . . simplify

4.75x = 87.875 . . . . . . . . . . . subtract 108.375

x = 18.5 . . . . . . . . . . . . . . . divide by 4.75

The market sold 7 pounds of fish and 18.5 pounds of lobster.

BC¯¯¯¯¯ is parallel to DE¯¯¯¯¯.

Nuetrik [128]

If BC is parallel to DE then ∠D ≅ ∠B and ∠E ≅ ∠C. Therefore

ΔABC is similar to ΔADE.

The sides of smaller triangle are in proportion with sides of bigger triangle.

Therefore we have the equation:

$\dfrac{AC}{AE}=\dfrac{AB}{AD}$

We have AC = x, AE = x + 15, AB = 8, AD = 8 + 10 = 18.

Substitute:

$\dfrac{x}{x+15}=\dfrac{8}{18}$ <em>cross multiply</em>

$18x=8(x+15)$ <em>use distributive property a(b + c) = ab + ac</em>

$18x=8x+120$ <em>subtract 8x from both sides</em>

$10x=120$ <em>divide both sides by 10</em>

$\boxed{x=12}$

<h2>Answer: AC = 12</h2>
