X = length of shortest side
Therefore the remaining sides will be x +2 and x + 7
x + x + 2 + x +7 = 45
3x + 9 = 45
3x = 36
x = 12
x + 2 = 14
x + 7 = 19
The sides are 12, 14, and 19 cm. long. Hope this helped!
Answer:
8
Step-by-step explanation:
Since we are adding small numbers we can use our hands to solve it.
1) We can use one hand to represent the value of 5
2)We use the other hand and lift tree fingers up.
3)counting the fingers will give you a total of 8
Answer:
So, there are 3 cards in total, which means your pobability of picking one card out of the 3 cards is %33.33. So the probability of picking a 7 is 1/3. Because the other two numbers are greater than 7, and you already picked 7 so you cannot pick it again, the probabitily of pick a number greater than 7 is %100, or 3/3.
I hope that answers your question! :)
Answer:
writing this down numerically gives us
3x+2=5x-1
(x-the number)
to solve...
add 1 to each side
3x+3=5x
subtract 3x from each side
3=2x
2x=3
divide by 2 to get x
x=3/2
x=1.5
