Answer:
15
Step-by-step explanation:
x - y = 10, then x = 10 + y
x + y = 20
substitute for x:
10 + y + y = 20
2y = 10
y = 5
x = 10 + 5 = 15
Just multiply both dimensions by 2 to make it into centimeters.
Therefore,
4*2 x 5*2 (in inches) will be:
8cm x 10cm (in centimeters)
We conclude that the dimensions of her postcard into a graphic on her web page will be 8x10 in centimeter units.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.

i am a mathematics teacher. if anything to ask please pm me
One is bigger than the other. To make sure u can find greatest common denominator and you will know
Well just show each par of the expression like you would show them 13+5 and then x 2 then -6 and +8. Just show each part of the expression
