Answer:
x = 9/25, y = 7/25, z = 4/25
Explanation:
step 1: solve for y in first equation to use substitution
y = -2x + 1
step 2: insert into second equation to eliminate y variable and work with two variables
3(-2x+1) + z = 1 (now distribute)
-6x + 3 + z = 1 (bring over the -3)
-6x + z = -2
step 3: now left with -6x + z = -2 and x + 4z = 1, so eliminate z
-6x + z = -2 (multiply by 4)
4(-6x + z = -2)
-24x + 4z = -8
-
x + 4z = 1 (brought down third equation)
-25x = -9
x = 9/25
then just plug in x into the third equation to solve for z, followed by plugging it into the first equation to solve for y. you should end with y = 7/25 and z = 4/25
Answer: The correct answer is D. None of the above
Explanation:
Although the first three alternatives may eventually contribute, none of them is a prerequisite for a successful marriage.
Living together before the wedding is meant to get to know each other better, but there is no indication that it will make the marriage last any longer. Likewise, religious and premarital counseling can help the couple, but without any guarantee. What makes the marriage successful is the couple's complicity, love, and tolerance for the defects they both have.
E. The number of farms per square kilometer
Answer: C. Industrialization created factory jobs in urban areas while eliminating agricultural jobs in rural areas.
Explanation:
In the late 19th century, industrialization was in full swing and technology was being created that made farming more efficient. This led to a loss of jobs for people in the rural areas who depended mostly on farming.
These people then had to move to urban areas where industrialization had led to the construction of factories that required more labor. This significantly increased rural to urban migration.
