The difference of two integers is thirty. the larger integer is two more than five times the smaller integer. Find the integers
Mnenie [13.5K]
X=2+5y
x-y=30

basically, all you're doing here is solving a system of equations. use the second equation to find out what x or y means. i'm going to solve it for x.

this is the new equation : x=30+y

now i plug this equation into the first one.

30+y=2+5y

30=2+5y-y
30=2+4y
28=4y
y=7

now that you know what y is, take that second equation we did in the beginning and plug in y.

x-7=30

solve for x

x=37



the two integers are 37 and 7.

What is the circumference of quadrilateral ABED in cm?
Natasha2012 [34]

the perimeter of quadrilateral ABED is 36.

<h3 /><h3>What is circumference?</h3>

A circumference is the total distance around a plane shape. Another name for circumference is called perimeter

To calculate the circumference of the quadrilateral, we use the formula below.

Formula:

  • Peri. of ABED = /AB/+/BE/+/ED/+/DA/............. Equation 1

From the Diagram,

Given:

  • /AB/ = /DC/ = 8 cm,
  • /BE/ = 2×/DA/ = 2×6 = 12 cm
  • /ED/ = √(6²+8²) = √(36+64) = √100 = 10 cm
  • /DA/ = 6 cm

Substitute these values into equation 1

  • Peri. of quadrilateral ABED = 8+12+10+6
  • Peri. of quadrilateral ABED  = 36 cm

Hence, the perimeter of quadrilateral ABED is 36.

What single decimal multiplier would you use to increase by 4% followed by a 3% increase
Mandarinka [93]

Answer:

1.0712

Step-by-step explanation:

if you increase by 4%, it means you will have a new total of 104%. In decimals it is 1.04 (divide your percentage by 100) after that you do the same with the 3% increase. you'll have a new total of 103%. In decimals 1.03. If you want to know what single multiplier you can use, you need to multiply the both decimals. So you get 1.04 x 1.03 = 1.0712

hope this will help you, have a nice day!
