Suppose there are 19x students, 1x teachers
19x+1x=400
20x=400
x=20
there are 20 teachers and 380 students.
Answer:
c. x > 6
d. λ = 3/100
Step-by-step explanation:
c. You have the idea for the necessary equation:
speed = wavelength·frequency
The inequality is x > 6.
__
d. If λ represents the wavelength in nanometers, the range restriction can be written ...
2/100 < λ < 5/100
A possible value of λ is 3/100.
Well since its +1 take that away from 88 and make it 87 then your gonna divide by 9. so 87 divided by 9=29/3 or 9.6inf
so x=9.6 infinite 6
