So first you would have to make the two have common denominators. What we can do for that is say that they both go into 12. 1/6 x 2 = 2/12 and 3/4 x 3 = 9/12. Then we can add the two which is 2/12 + 9/12 = 11/12.
Answer:
8 possible seats
Step-by-step explanation:
Given
---booths
--- hostess
Required
Number of possible seats (order is important)
If order is important, then we solve using permutation
i.e.
So, we have:
This gives:
Expand
Answer:
a = 16
Step-by-step explanation:
The altitude YB is at right angles to the base XZ , then
∠ YBZ = 90° , so
6a - 6 = 90 ( add 6 to both sides )
6a = 96 ( divide both sides by 6 )
a = 16
The answer is C I just did this
Answer:
RS = XY (since the two a triangles are similar, you have to match the sides up and then set the values equal to eachother to find the value of x)
3x +2 = 5x -3 (subtract 5x from both sides)
-2x +2 = -3 (subtract 2 from both sides)
-2x = -5 (divide both sides by -2 to isolate x)
x = 2.5 (take the value of x and plug it into the expression given for RS)
3(2.5) +2 (multiply)
7.5 +2 (add)
9.5 (this is the length of RS)
Step-by-step explanation:
I hope this helps :)
