What is the first term of the geometric sequence presented in the table below?

1 answer:

8 0

176 = a1 * r^4
704 = a1 * r^6

dividing:-

r^2 = 706/174 = 4 so r = +/- 2

a1 = 176 / 2^4 = 176/16 = 11

So 11 is the first term

Four times a number, decreased by eight equals twelve. What is the number?

AleksandrR [38]

Let the number be x.

4x - 8 =12

4x =12 +8 ( you bring the eight over to the 12, it becomes positive )

4x = 20

x = 20÷4

x = 5

The opposite angles of a parallelogram have measures of (3x-20) and (x+15). Find x

KiRa [710]

ANSWER

The value of x is,

$17.5$

EXPLANATION

We were given that the opposite angles of a parallelogram are

$3x - 20$ and $x + 15$ .

The opposite angles of a parallelogram are equal.

We can write the equation below in x and use to find the value of x.

$3x - 20 = x + 15$

We group like terms to obtain,

$3x - x = 15 + 20$

This implies that,

$2x = 35$

We divide both sides of the equation by 2 to obtain,

$x = 17.5$

Step-by-step explanation:

b/h = D +g^3

Multiply each side by h

h* b/h = h*D +hg^3

b = h*D +hg^3
