Ben is 444 times as old as Ishaan. 666 years ago, Ben was 666 times as old as Ishaan.
How old is Ben now? i will give brainly to whoever answers it right!!!

Answers

Answer:It means Ishaan is 15 years old now

Step-by-step explanation:Ben is 4 times as old as Ishaan

and

6 years ago , Ben wad 6 times as old as Ishaan

Now

Let's assume that Ishaan is x years old now.

It means age of Ben = 4x

And 6 years ago , ben was 6 times as old as Ishaan

6 years ago , age of Ishaan = x-6

and age of ben = 4x-6

it means

4x-6 = 6(x-6)

4x-6 = 6x-36

add 6 to both sides

4x= 6x -30

Subtract 6x from both sides

-2x = -30

divide both sides by -2

x=15

Answer:

Ben is 60 Ishaan is 15

You pay 15 dollars for something that was 25% off. What was the original price of the hat before the discount?

Answers

Answer:$18.75

Step-by-step explanation: 15*0.25=3.75

15+3.75=18.75

Answer:

Step-by-step explanation:

So we first subtract 25% from 100% so we can see what percent 15 is:

100 - 25 = 75 so 15 is 75% of ___:

This gives us a standard percentage problem, so:

75% = 0.75

we can rewrite the equation as a one-step equation:

15 = 0.75a

Dividing both sides by 0.75 and swapping sides gives

a = 15 ÷ 0.75 = 20

So the original price of the hat was $20

because 25% is 1/4, and 75% is 3/4 and 15 is therefore 3/4:

15 ÷ 3 = 5

5 x 4 = 20

Given: l || m; 1 = 20x + 5; 2 = 24x - 1 Using theorems pertaining to transverals and parallel lines, prove that m∠1 + m∠2 = 180o Find the value of x.

Answers

Answer:

The answer to your question would be, x=4.

Step-by-step explanation:

∠1 and ∠2 are interior angles between parallel lines that are on the same side of a transversal, so they are supplementary.

Therefore, (20x+5)+(24x-1) = 180

44x = 176

x=4

I hope this helps! Have a great day! :]

For the given set of parallel lines l and m , value of x is equals to 4.

What are parallel line?

"Parallel lines are such lines which are equidistant from each other and never intersect in the same plane."

According to the question,

l ║ m ,

As per theorem pertaining to transversal and parallel lines ,

∠1 and ∠2 are supplementary if and only if they are interior angles.

m∠1 + m∠2 = 180° _____(1)

∠1 = 20x + 5

∠2 = 24x - 1

Substitute the value ∠1 and ∠2 in (1), we get

20x + 5 +24x - 1 = 180°

⇒ 44x + 4 = 180°

⇒ 44x = 176

⇒ x = 4

Hence, for the given set of parallel lines l and m , value of x = 4.

Step-by-step explanation:

I have never had this question before though if I had I would have put this answer hope I helped Thanks for waiting.

Answer:

Nailah's is wrong so far. it equals to 5 yards and you need 7-9 yards with 5 pieces of ribbon.

So Nailiah's would be 5 purple's to equal 8.33 Yards which is between 7-9 yards.

add 2 green and 1 blue to Yu's that would equal to 8.66 Yards which is between 7 and 9 yards. Remember that Yu has 3 pieces of ribbon

and for Elena's add 5 blue's and 1 green that would equal to 7.5 yards which is between 7 and 9 yards. remember that Elena has 6 pieces of ribbon
