if 1/2p=2 1/2q, find q:p

its 2 and a half not 21/2

Answers

Answer:

1/5 = q/p, or q:p

Step-by-step explanation:

You might want to rewrite 1/2p=2 1/2q as (1/2)p = (2 1/2)q.  

To remove the fractions, multiply both sides by 2:

p = 2(2 1/2)q  becomes p = 5q.

Dividing both sides by 5 yields p/5 = q.

Dividing both sides by p yields 1/5 = q/p, or q:p

rewrite them so that they have a common denominator (and whole number numerators

For both fractions to have a common denominator, find the lowest common multiple of both denominators

5 = 5, 10, 15, 20, 25, 30, 35, 40

10 = 10, 20, 30, 40

Step-by-step explanation:

200 tickets were sold in a school’s annual musical performance. Students' tickets cost $2.50 each and parents tickets cost $3.50 each. The total amount collected was $537. How many tickets were sold for parents?

Answers

Answer:

Step-by-step explanation:

 

number of students ticket sold = x

number of parent tickets sold = y

 

If a total of 96 tickets were sold

x+ y =96     ----      eq 1

 

 

If a total of 96 tickets were sold for $306.25

2.50x + 3.75y=306.25  ---- eq 2

 

x+ y =96

y=96-x

 

substitute value of y in equation 2

2.50x + 3.75 (96-x)=306.25

 

2.50x + 360 -3.75x =306.25

 

- 1.25 x = -53.75

 

x = 43

therefore the answer would be y=96-x=96-43=53

find the equation of the line shown​

Answers

Answer:

y = 2x

Step-by-step explanation:

We know the y intercept of the line is 0

We can find the slope

(0,0) and  (3,6)

m = (y2-y1)/(x2-x1)

   = (6-0)/(3-0) = 6/3 = 2

The equation of a line in slope intercept form is

y= mx+b where m is the slope and b is the y intercept

y =2x+0

y = 2x


The owner offers a payment plan where the total cost of the
mountain bike is paid in 3 equal monthly payments. Determine the amount
of each monthly payment.

Answers

Answer:

$131.85

Step-by-step explanation:

First, we need to find the net price (after discount and tax) It's a 15% discount, so just find 85% (100-15=85) of the original price. You'll get $373.15.

For tax, multiply by 1.06, since it's a 6% tax (1+.06). You'll get $395.539.

You're paying over 3 months time, so to find payment each month just divide by 3.

395.539/3 = 131.8463333

Round to 131.85

Your answer is $131.85 dollars per month

3) The start-up cost to join Tunes is $7.95 plus $0.95 per song downloaded. If Will spent $26, write and solve a linear equation to find how many songs he downloaded​

Answers

Answer:

X = 19 songs

Step-by-step explanation:

Y = 0.95x + 7.95

26 = 0.95x + 7.95

Solve for x

26-7.95 =0.95x

18.05/0.95 = x

X = 19 songs
