If JK = 4, KL = 3x, and JL = 7x, what is JL? Simplify your answer and write it as a proper fraction, mixed number, or integer.

Answers

Answer 1

Answer:

JL = 7

Step-by-step explanation:

If JK = 4, KL = 3x, and JL = 7x, what is JL?

From the diagram given in tbe question,

JK + KL = JL

4 + 3x = 7x

Collect like terms

4 = 7x - 3x

4 = 4x

4x = 4

x = 4/4

x = 1

Since JL from the diagram = 7x

Hence:

7 × 1 = 7

JL = 7

Audrey wants to ride her bicycle 44 miles this week. She has already ridden 12 miles. If she rides for 5 more days, write and solve an equation which can be used to determine x, the average number of miles she would have to ride each day to meether goal.

Answers

Answer:

Step-by-step explanation:

Final answer:

The question involves creating and solving a basic algebraic equation. Audrey needs to cycle an average of 6.4 miles each day over the next 5 days to reach her total goal of 44 miles for the week.

Explanation:

To solve this problem, we can establish an equation based on the information given. Audrey's goal is to ride a total of 44 miles this week and she has already ridden 12. If she rides for 5 more days, we need to determine how many miles she should cover each day to reach her goal. We denote x as the average number of miles she needs to ride each day.

The communication of her plans can be expressed through this equation: 12 miles + 5 days * x miles/day = 44 miles. Next, we need to solve the equation for x. In order to isolate x, you subtract 12 from both sides of the equation resulting in: 5x = 44 - 12, which simplifies to 5x = 32.

Finally, you divide both sides of the equation by 5 to get: x = 32 ÷ 5. So, x equals 6.4. This means that Audrey needs to cycle an average of 6.4 miles each of the coming 5 days to reach her total goal of 44 miles.

since the polygons ABCD and LMNK are similar then the sides will have the same size ratio so then put 6 over 58 = 3 over x then cross multiply so you get 6x=174 so x equals 29
