Answer: x = 28

Step-by-step explanation:

x + 20=3x-36

20=2x-36

56=2x

56/2=28

So 28= x

X= 28


X + 20 = 3x - 36
20 = 2x - 36
56 = 2x
28 = x

Paul [167]

Answer:

Step-by-step explanation:

Given that the  mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days.

Let X be the incubation time for a type of fertilized egg kept at a certain temperature is 25 days.

X is N(25, 1)

a) Normal curve is in the attached file

b) the probability that a randomly selected fertilized egg hatches in less than 23 days

=P(X

we convert x into Z score and use std normal distn table to find probability

P(X

i.e. we can say only 2.5% proportion will hatch in less than 23 days.

X + 9y = 8 x − 4y = –18
loris [4]

Step-by-step explanation:

x + 9y =  - 18 \\ 8x - 4y =  - 18 \\ x =  - 18 - 9y \\ 8( - 18 - 9y) - 4y =  - 18 \\  - 144 - 72y - 4y =  - 18 \\  - 76y = 126 \\ y =  - 1.66 \\

x =  - 18 - 9y \\ x =  - 18 - 9( - 1.66) \\ x =  - 18 + 14.94 \\ x =  - 3.06

Answer:

  F.  x ≤ -5

Step-by-step explanation:

Translating the diagram to more conventional symbols, we have ...

  4x +12 ≤ -8

  4x ≤ -20 . . . . . . . subtract 12 from both sides

  x ≤ -5 . . . . . . . . . divide both sides by 5
