14(2)

All 3 do not equal to each other. Proving that Juwon's statement is wrong.

Answer:

The first two are equivalent but different than the third.

Step-by-step explanation:

8n+6 = 2(4n+3) => 6=6\\8n+6 = 14n => 6n = 6 => n = 1\\\\

The first two are identical by factoring 2 out of the first one, or distributing 2 in the second one.

The equality of the first and third equations, suggests that it is only true for n = 1.

To prove it wrong, find a number that shows the inequality:

n = 2\\8n+6 = 2(4n+3) = 22\\14n = 28\\\\22 \neq 28

Washing his dad's car alone, eight-year-old Levi takes 2.5 hours. If his dad helps him, then it takes 1 hour. How long does it t
Dmitry [639]

Answer:

Levi's dad takes 1.67 hours to wash the car by himself

Step-by-step explanation:

* Lets explain how to solve the problem

- Levi takes 2.5 hours to wash his dad's car alone

- Levi and his dad take 1 hour to wash the dad's car together

∵ Levi takes 2.5 hours to wash the car alone

∴ The rate of Levi is 1/2.5 car/hr

∵ His dad takes x hours to wash the car alone

∴ The rate of his dad is 1/x car/hr

∵ They working together for 1 hour to wash the car

- The equation of the work is rate of Levi × t + rate of his dad × t = 1

∵ t is the time of working together

∵ t = 1 hour

∴ \frac{1}{2.5}(1)+\frac{1}{x}(1)=1========\frac{1}{2.5}+\frac{1}{x}=1

- Multiply both sides by 2.5x to cancel the denominators

∵ \frac{1}{2.5}(2.5x)=x=====\frac{1}{x}(2.5x)=2.5

∵ 1 × (2.5x) = 2.5x

∴ x + 2.5 = 2.5x

- Subtract x from both sides

∴ 2.5 = 1.5x

- Divide both sides by 1.5

∴ x = 5/3 ≅ 1.67

∵ x is the the time of his dad to wash the car alone

∴ Levi's dad takes 1.67 hours to wash the car by himself

Answer:

5 meters

Step-by-step explanation:

So Zane starts at -25 meters, then, after 35 seconds, he makes it to the top. The questions is asking how high he climbed every 7 seconds. As we know, 7x5 is equal to 35. this means that we can divide 35 and 25 by 5 to get the answer. 25/5 is equal to 5, so that means he climbed 5 meters every 7 seconds. I hope this helps!

Find the measure of an angle such that the difference between the measures of its supplement and four times its complement is 30
Katarina [22]

Answer:

70 degrees

Step-by-step explanation:

x = angle

180 - x = it's supplement

90 - x = it's compliment

(180 - x) - 4(90 - x) = 30

180 - x - 360 + 4x = 30

reducing

3x = 210

x = 70
