Okay, let's take a look:

I am going to add up the numbers and see where we get.

3+3+3+3= 12
4+4+4= 12

I counted up to when they would land on the same number. They landed on 12. So, every 12 days he will run and practice his trumpet on the same day.

I hope this helped!

Answer:

n = -2

Step-by-step explanation:

$\frac{-5}{6}n-\frac{1}{6}=\frac{-1}{3}+\frac{11}{6}\\\\\frac{-5}{6}n=\frac{-1}{3}+\frac{11}{6}+\frac{1}{6}\\\\\frac{-5}{6}n=\frac{(-1)*2}{3*2}+\frac{11}{6}+\frac{1}{6}\\\\\frac{-5}{6}n=\frac{-2}{6}+\frac{11}{6}+\frac{1}{6}\\\\\frac{-5}{6}n=\frac{-2+11+1}{6}\\\\\frac{-5}{6}n=\frac{10}{6}\\\\n=\frac{10}{6}*\frac{6}{-5}\\\\n= -2$

My 4-digit number is a palindrome (meaning, that it does not change if you write it backwards), and it has remainder 21 when you

vitfil [10]

Answer: 1221

Step-by-step explanation:

Given : A 4-digit number is a palindrome .

If it has remainder 21 when you divide it by 100, then last two digits are 21.

So required palindrome = _ _ 21

since palindrome does not change if you write it backwards, so first two numbers should be reverse of 21 = 12

hence, the complete palindrome = 1221

So the number is 1221.

Can you please help me? Thanks!!!!

The answer is 25 degrees.

This is how you solve the equation, first you must know that the straight like ABC=180, DBC is 130, so the remaining amount is 50 degrees, BE is a bisector of ABD which means it splits ABD right down the middle. So ABE+EBD=50 degrees, 25+25=50 since both sides MUST be equal in order for BE to be a bisector of ABD.

Howard has a garden in the shape of a rectangle. The length is 5.4 meters The width is 1.5 meters Howard will increase both the

Inessa05 [86]

The perimeter of the enlarged garden is 16.56 meters.

Step-by-step explanation:

The garden is in the shape of a rectangle.

The length of the rectangle = 5.4 meters.
The width of the rectangle = 1.5 meters.

The Rectangle is enlarged by increasing the length and width by 20%.

To find the enlarged length :

The original length 5.4 is increased by 20%.

⇒ (20/100) × 5.4

⇒ 0.2 × 5.4

⇒ 1.08

The 20% of the length is 1.08
The enlarged length is 5.4 + 1.08 = 6.48 meters.

To find the enlarged width :

The original width 1.5 is increased by 20%.

⇒ (20/100) × 1.5

⇒ 0.2 × 1.5

⇒ 0.3

The 20% of the width is 0.3
The enlarged width is 1.5 + 0.3 = 1.8 meters.

The perimeter of the enlarged rectangle is found by substituting the enlarged values of length and width in the perimeter formula.

Perimeter of the enlarged rectangle = 2 (length + width)

⇒ 2 (6.48 + 1.8)

⇒ 2 × 8.28

⇒ 16.56 meters.

∴ The perimeter of the enlarged garden is 16.56 meters.
