Mathematics

Answer:

14

Step-by-step explanation:

2x + y = 20                                                                                     (1)

2x + 3y = 36                                                                                  (2)

(2) - (1) ⇔ (2x - 3y) - (2x + y) = 36 - 20

          ⇔ 2y = 16

          ⇔ y = 8                                                                               (3)

From (3) and (1), we have:

    2x + y = 2x + 8 = 20

⇔ 2x = 12

⇔ x = 6

So: C = x + y = 6 + 8 = 14

Conclusion : C = 14

X+y =10<br> Y=-x+10<br> System of equations
katovenus [111]

Answer:

Infinite solutions

Step-by-step explanation:

x + y = 10

y = -x + 10

We'll choose one equation to use, x + y = 10

Substitute y with -x + 10

x - x + 10 = 10

x cancels each other out

10 = 10, which would also mean 0 = 0

This means the answer will validate with any number

What are the missing numbers in the sequence 5/8 11 14?
algol [13]

The complete sequence solved by arithmetic progression is 5 8 11 14 17.

<h3>What is arithmetic progression?</h3>

The difference between every two successive terms in a sequence is the same; this is known as an arithmetic progression (AP). It is possible to obtain a formula for such nth term of a AP using this kind of development.

The numbers 5, 8, 11, 14,... belong to the arithmetic progression (AP) since they follow a pattern in which the previous number is added by 3 to get each new number.

nth term = a + (n-1)d

where, a is the initial term (=5)

n is the total terms in the series (=5)

d is the common difference (8-5=3)

Substitute the values in the formula to get the result;

5th term = 5 + (5-1)3

              = 5 + (4×3)

5th term = 17

Therefore, the last term (5th term) of the series is 17.
