Solve for X in the 2nd equation:

x+2z = 0

Subtract 2z from both sides:

x = -2z

Replace x in the first equation with -2z

-2z +y -z = 1

Combine like terms:

-3z +y = 1

Add 3z to both sides:

y = 3z +1

Replace x and y in the 3rd equation:

2(-2z) + 2(3z+1) = 4

-4z + 6z + 2 = 4

2z +2 = 4

2z = 2

z = 1

Now replace z with 1 in the other equations for x and y:

x = -2z = -2(1) = -2

y = 3z +1 = 3(1) +1 = 3+1 = 4

So you have x = -2, y = 4 ans z = 1

The answer would be written as (-2,4,1)

the sum of two consecutive integers is less than 83. find the pair of integers with the greatest sum.

pychu [463]

$x-first\ number\\x+1-second\ number\\\\x+x+1=83\\2x=82\\x=41\\x+1=42\\\\42+41=83,\ so\ first\ number\ could\ be\ 40\ and\ second\ 41,\ because\\sum\ must\ be\ less\ than\ 83.

Which algebraic expression repesents the phrase? Cindy studied seven more hours than Nikki studied. a. n+7 b. 7-n c. 7n d. n/7

elixir [45]

Answer:

Option a is the correct choice.

Step-by-step explanation:

Let n be number of hours studied by Nikki.

We are told that Cindy studied seven more hours than Nikki studied. This means that number of hours studied by Nikki plus 7 hours equals to the number of hours studied by Cindy.

We can represent this information in an expression as :

$\text{The number of hours studied by Cindy}=n+7$

We can see from our given choices that expression given in option a represents the number of hours studied by Cindy in terms of hours studied by Nikki.

Therefore, option a is the correct choice.
