Divide the amount saved by the original price then multiply by 100 to get the percent:

6/40 = 0.15

0.15 x 100 = 15%

find three consecutive integers. such that 4 times of first integer is 18 more than the sum of the second and third integer

Juliette [100K]

Three consecutive numbers are x, x+1 and x+2.

Four times the first integer is 4x

The sum of the second and third is (x+1)+(x+2)=2x+3.

So, we have

$4x = 2x+3+18\iff 4x=2x+21$

Subtract 2x from both sides:

$2x=21$

Divide both sides by 2:

$x=10.5$

So, you can't have three consecutive integers such that four times the first is 18 more than the sum of the other two: the three numbers would be 10.5, 11.5, 12.5.

In fact, you have

$4\cdot 10.5 = 42$

and

$11.5+12.5+18 = 24+18=42$

The ratio of green beads to yellow beads in a bracelet is three to four. The total number of beads is 14. How many green beads a

Alja [10]

Answer:

There are 6 green beads there.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of green beads

y is the number of yellow beads

The ratio of green beads to yellow beads in a bracelet is three to four.

This means that

$\frac{x}{y} = \frac{3}{4}$

$3y = 4x$

$y = \frac{4x}{3}$

The total number of beads is 14.

This means that $x + y = 14$

How many green beads are there ?

This is x.

$x + y = 14$

However

$y = \frac{4x}{3}$

$x + \frac{4x}{3} = 14$

Using multiplying by the gcm(3)

$3x + 4x = 42$

$7x = 42$

$x = 6$

There are 6 green beads there.

the giant swallowtail is the largest butterfly in the united states . its wingspan can be as large as 16 centimeters. what is th

Anna11 [10]

The maximum wingspan in millimeters would be 160.

The prefixes, Kilo, Hecto, Deca, Deci, Centi, and Milli all increase by powers of ten. An easy way to remember this is

King Kilo
Henry Hecto
Died Deca
Drinking Deci
Chocolate Centi
Milk Milli

Since Centi is greater than Milli by one space, you increase by ten, which means you move the decimal once to the right.

Hope this helps! :)
