The sides are in ratio 2:3:4
So this means
shortest side = 2x
medium side = 3x
longest side = 4x
for some number x
The shortest side is given to be 5 cm, meaning that
2x = 5
x = 5/2 <--- divide both sides by 2
x = 2.5
Since x = 2.5, we can now say...
shortest side = 2*x = 2*2.5 = 5
medium side = 3*x = 3*2.5 = 7.5
longest side = 4*x = 4*2.5 = 10
The three sides of the triangle are: 5, 7.5, 10
They add to 5+7.5+10 = 22.5
The perimeter of this triangle is 22.5 centimeters
The answer would be 9 87/100
Answer:
50b>100b
Step-by-step explanation:
the book (b) is your variable in this case (a variable is just an item and im using b because it stands for books lol)
the book costs 50 cents, so we are going to put 50 cents in front of b(the books) so like this----> 50b: this reads as "the books are 50 cents."
now, the "more than" always means this sign ">"
and here's the tricky part, since it says " double a book with a red sticker." you're going to want to multiply ( 50*2=100), and we do this because of the word "double" (double means two) this is how you would write this scenario.
now im not sure if you wanted me to solve for it, but if curious you would just have to divide. the 50 and the 100 to get an answer.
