Answer:
1) Yes
2) No
3) Yes
4) Yes
Step-by-step explanation:
Remember the rule: the sum of the two shortest sides must be bigger than the longest side. From there, the answers should be obvious. Just add up the smallest sides for each triplet of lengths and see if that is bigger than the largest side.
7 + 14 > 18, therefore this can be a triangle
3 + 8 < 17, therefore this can't be a triangle
3.2 + 9.0 > 11.5, therefore this can be a triangle
6 + 7 > 8, therefore this can be a triangle
Answer:
It should be cents

Answer:
Adding the variables
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
Given y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 24 when x = 6 , then
24 = 6k ( divide both sides by 6 )
4 = k
y = 4x ← equation of proportion
When y = 16, then
16 = 4x ( divide both sides by 4 )
4 = x

Turn the 2 1/4 into a mixed number:
1/2x + (-7) - 9/4x + 2
Multiply 1/2x by 2/2:
2/4x + (-7) - 9/4x +2
Add common terms:
-7/4x - 5
Turn -7/4x into a mixed number:
-1 3/4x -5
So your answer is
A.) -1 3/4x - 5
