8y-2d=0 5y+4d=26 1/4

Anit [1.1K]

Answer:

y = 1

d = 4

Step-by-step explanation:

8y - 2d = 0 ---------------(I)

5y + 4d = 26 1/4

5y + 4d = 105/4 ------------------(II)

(I)*2 16y - 4d = 0

(II) <u>5y + 4d = 105/4</u> {add (I) &(II)}

21y = 105/4

$y = \frac{105}{5*21}\\\\y=\frac{105}{105}\\\\y = 1$

Substitute y =1 in equation (I)

8*1 - 2d = 0

8 - 2d = 0

-2d = -8

d = -8/-2

d = 4

Sav [38]

The answer would be the sequence has a common ratio of 4.
The explanation for this would be:
To get the common ratio for get the simplest form of the two numbers, so 12/3 = 4 and 48/12 = 4So we know that their common ratio is 4.
To check:
3 x 4 = 12
12 x 4 = 48
48 x 4 = 192
192 x 4 = 768

The sum of 5 times a number and <br> minus −2, plus 7 times a number

Olenka [21]

Answer:

12x + 2

Step-by-step explanation:

Let the number be represented by x.

Then five times the number = 5*x

Seven times the number = 7*x

Sum of 5 times the number minus -2 = $5*x - (-2)$ = $5x +2$
