Answer:
Only one solution
x=1/2
Step-by-step explanation:
Collect like terms.
3/2x=3
Solve for x.
6x=3
x=1/2
You use Pythagorean theorem...a^2+b^2=c^2
a=12ft
b=47-31.. height of the triangle
c=distance between two roof tops
(12)^2+(16)^2=c^2
144+256=c^2
400=c^2, take square root of both sides
c=20ft
Answer:
B. Jenny paid $322 for 23 T-shirts, which is a rate of $14 per T-shirt.
Step-by-step explanation:

Therefore, B is correct.
Answer:
The total number of ways in which the 5 people can sit is: 5!=120: 5!=120
Let us assume that person d and e are sitting together and are taken as a single entity, the number of ways in which 4 people can sit is: 4!=24: 4!=24
The number of ways in which d and e are not sitting together: 1120−24=96.
