Answer:

D) -3y + 8z

Step-by-step explanation:

2x - 2y + 5z - 2x - y + 3z

first, group the same variables together.

2x - 2x - 2y - y + 5z + 3z

then, this step which I don't have a name for.

2x - 2x = 0x.

-2y - y = -3y

5z + 3z = 8z

0x - 3y + 8z

or, -3y + 8z

What is the formula for the nth term of the given sequence? -17, -8, 1
Citrus2011 [14]

Answer:

The n^{th} term of A.P sequence

tₙ = 9 n - 26

Step-by-step explanation:

<u><em>Step(i):</em></u>-

Given sequence

                   - 17 , -8 , 1 .......

first term   = -17

Second term =  - 8

The difference of first two terms

                        d = - 8 -(-17) = -8+17 = <em>9</em>

The difference of next two terms

                        d = 1 - (-8) = 1+8 =   9

∴ The given sequence is  in A.P ( Arthimetic progression)

<u><em>Step(ii):-</em></u>

The n^{th} term of A.P sequence

                t_{n}  = a + ( n-1 ) d

Given a = - 17 and  d = 9

                t_{n}  = -17 + ( n-1 ) 9 = - 17 + 9 n -9 = 9 n - 26

<u><em>Final answer</em></u>:-

The n^{th} term of A.P sequence

tₙ = 9 n - 26

A solution is prepared by dissolving
Whitepunk [10]

Answer:

13.79%

Step-by-step explanation:

A solution is made by dissolving 24 millimeters of saline in 150 millimeters of pure solution

Therefore percent of saline in the pure solution can be calculated as follows

= 24/24+150 × 100

= 24/174 ×100

= 0.1379 ×100

= 13.79%

Hence the percent of saline in the pure solution is 13.79%
