1st option
Step-by-step explanation:
Given the 2 equations
2x + 5y = 19 → (1)
y = 3x - 3 → (2)
Substitute y = 3x - 3 into (1)
2x + 5(3x - 3) = 19
Answer:
B. 
Step-by-step explanation:
The question is not properly presented. See attachment for proper presentation of question
From the attachment, we have that:




Required
Order from greatest to least
First, we need to simplify each of the given expression (in decimals)



Take square root of 3


--- approximated



Take π as 3.14


--- approximated
List out the results, we have:

Order from greatest to least, we have:

Hence, the order of arrangement is:

i.e.

Step-by-step explanation:
Given
If x = 4 Then
3x + 1 = 3 * 4 +1 = 12 + 1 = 13
The answer should be 13.
