<u>Problem A:</u> 26.34
<u>Problem B:</u> 90.537
<u>Problem C:</u> 309.02
<u>Problem D:</u> 170.084
To solve this problem, let us say that the number is
called x and let us do this step by step.
1st step: 3 is added to the number, therefore:
x + 3
2nd step: the sum is tripled, therefore:
3 (x + 3)
3rd step: the result in the 2nd
step is equal to 27 more than the original number, therefore:
3 (x + 3) = x + 27
4th step: find for the value of x using the
equation
3 x + 9 = x + 27
3 x – x = 27 – 9
2 x = 18
x = 9
Answer:
The number is 9
Answer:
false

if is 6= you need to time by it self like: 6×6=is ur answer
Answer:
<h3>
5 < x < 27 {x - lenght of unknown side}</h3>
Step-by-step explanation:
If we have triangle of sides: a, b, c, and a < b < c (or b<a<c) then:
for triangle to exist:
a + b > c
So:
if a=11, b=16 then 11 + 16 > c ⇒ c < 27
if a=11, c = 16 then 11 + b > 16 ⇒ b > 5
We don't know if the unknown side (x) is the longest or not, so it has to be greater than 5 and less than 27
5 < x < 27
