Answer:
39
Step-by-step explanation:
Let, total rooms girls booked be x and total rooms girls booked be y.
entire hotel was booked except two rooms.
so, total = 158-2 = 156
x+ y = 156
this is equation 1.
also, girls are using three times more room than boys.
so, y=3x
substituting y=3x in 1st equation,
x+ 3x = 156
or, 4x = 156
or, x= 156/4
x= 39
Answer:
6x = − 4 x − 4 = 0 =
Step-by-step explanation:
The next larger tenth is 76.1 .
The next smaller tenth is 75.9 .
Neither of those is any closer to 76 than 76 is.
76 is already rounded to the nearest tenth.
Answer:
The points (x,y,z) that respond to Ir-r0I =1, are all that describes the form 
with:
-1+x₀<x<1+x₀
-1+y₀<y<1+y₀
-1+z₀<z<1+z₀
Step-by-step explanation:
All points required in this problem came from applying the definition of modulus of a vector:
Ir-r0I =1.
