6 - 2x = 6x - 10x + 4
yarga [219]

6 - 2x = 6x - 10x + 4

6 - 2x =  - 4x + 4

6 =  - 4x + 4 + 2x

6 =  - 2x + 4

- 2x + 4 = 6

- 2x = 6 - 4

- 2x = 2

x =  \frac{ \:  \:  \: 2}{ - 2}

x =  - 1

Therefore , the value of x = -1

a 4-meter ladder leans up a wall the foot of the ladder is 2 meters away from the wall how far up the wall will the ladder reach
svlad2 [7]
The answer is 3.46 meters

You can get the answer by using the pythagorean theorem, since the ladder and the wall form a right triangle.

c^2 = a^2 + b^2
4^2 = 2^2 + b^2
16 = 4 + b^2
12 = b^2
b = sqrt(12) or 3.46 meters

Given the third term of an arithmetic sequence less than the fourth term by three. The seventh term
UNO [17]

Answer:

The first term is -6 and common difference is 3

Step-by-step explanation:

The nth term of an arithmetic progression is expressed as;

Tn = a + (n-1)d

T3 = a+2d

T4 = a + 3d

If the third term of an arithmetic sequence less than the fourth term by three

T3 = T4 - 3

a+2d = a+3d - 3

2d - 3d = -3

-d  = -3

d = 3

Similarly;

T7 = a+6d

T5 = a+4d

If the seventh term  is two times the fifth term, the;

T7 = 2T5

a+6d = 2(a+4d)

a+6d = 2a+8d

Since d = 3

a + 6(3) = 2a + 8(3)

a+18 = 2a + 24

a-2a = 24 - 18

-a = 6

a = -6

Hence the first term is -6 and common difference is 3
