Answer:

Infinitely many solutions.

Step-by-step explanation:

2 (n - 1) + 4n = 2 (3n - 1) Let's simplify this to solve it.

2n - 2 + 4n = 6n - 2 Distribute 2(n-1) and 2(3n-1)

2n + 4n - 2 = 6n - 2 Rearrange the left side of the equation.

6n - 2 = 6n - 2 Add 2n + 4n.

-6n -6n Subtract 6n from both sides.

-2 = -2

the answer is infinitely many solutions, meaning that n can be any real number.

Find the distance between the points (1, 5) and (1, -4). 3 √(41) 9

8_murik_8 [283]

Answer:

The distance between the givens points is 9 unit

Step-by-step explanation:

Given points are as :

A = ( 1 , 5 )

B = ( 1 , - 4 )

So, The Distance between points A and B = AB

Now, From Distance formula

AB = $\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}$

Or, AB = $\sqrt{(1 - 1)^{2}+( - 4 - 5)^{2}}$

Or, AB = $\sqrt{0 +81}$

Or, AB = $\sqrt{81}$ = 9

Hence The distance between the givens points is 9 unit Answer

Sergio039 [100]

Step-by-step explanation:

his father's age= 4x

his mother's age= 4x- 7

his age= x

x+4x+4x-7=101

x+ 4x+ 4x= 101+ 7

9x= 108

$\frac{9x}{9}$ = $\frac{108}{9}$

x= 12

Tesfa is 12 years old
