3 (x -1) = 5x +3 -2x

Vika [28.1K]

Steps to solve:

3(x - 1) = 5x + 3 - 2x

~Distribute left side

3x - 3 = 5x + 3 - 2x

~Combine like terms

3x - 3 = 3x - 3

~Subtract 3x to both sides

-3 = -3

~Add 3 to both sides

0 = 0

All real numbers are solutions.

Best of Luck!

Ling worked three more hours on Tuesday than she did on Monday. On Wednesday, she worked one hour more than twice the number of

Nina [5.8K]

Let x be the number of hours ling work on monday.

We know that she worked three more hours on tuesday that in monday, this can be express as :

$x+3$

We also know that in wednesday she worked on more hour than twice the number on mondays, this can be expressed as:

$2x+1$

The total number of hours she worked this three days in two more than five the number of hours she worked on monday, this can be express as :

$5x+2\\$

Now , once we have all the expressions we add the expressions of the days and equate them to the total

$x+(x+3)+(2x+1)=5x+2$

Now we solve the equation

$x+(x+3)+(2x+1)=5x+2\\x+x+3+2x+1=5x+2\\4x+4=5x+2\\5x-4x=4-2\\x=2$

Therefore , she worked 2 hours on monday.

Point B has coordinates (2,1). The x-coordinate of point A is negative 1. The distance between point A and point B is 5 unit

Gwar [14]

Answer:

A = (-1,5) or (-1,-3)

Step-by-step explanation:

A = (-1,y) B = (2,1)

(Distance from A to B) = √[(-1-2)² + (y-1)²] = 5

=√[9 + y² - 2y + 1] = 5

Squaring on both sides

= y² - 2y + 10 = 25

=y² - 2y -15 = 0

= (y-5)(y+3) = 0

y = 5 or -3

Therefore, A = (-1,5) or (-1,-3)
