Simplify 18 - 2[x + (x - 5)].
8 - 4x
28 - 4x
28 - 2x

18 - 2[x + (x - 5)]
=(-2x + -2x) + (18 + 10)
= -4x + 28

Find the width of the rectangle. **Weegy:** Let x be its width, then its length is (x + 3). perimeter = 2x + 2(x + 3) = 22, solve the equation we get x = 4. Its width is 4 inches. **User:** Given the line 2x - 3y - 5 = 0, find the slope of a line that is perpendicular to this line. **Weegy:** Given the line 2x - 3y - 5 = 0, the slope of a line that is perpendicular to this line is -3/2. **User:** A man invests a certain amount of money at 2% interest and $800 more than that amount in another account at 4% interest. At the end of one year, he earned $92 in interest. How much money was invested in each account? **Weegy:** Let the man invest an amount x at 2% interest.
Then, [ he invests an amount (x+800) at 4% interest.
Total simple interest for one year is
x*2/100 + (x+800)*4/100 = 92
2x+4x+3200 = 9200
6x = 9200-3200
6x = 6000
x = 1000
So the man invested $ 1000 at 2% interest and $ 1800 at 4% interest. ] **User:** What is the algebraic expression for "the difference between seven times a number and three times that number"? **User:** Describe the location of the point that has the following coordinates.

Given: y varies directly with x and has a constant rate of change of 7. When the value of y is 12, then the value of x would be 12/7 .

If y = 7x

when y = 12

x = 12/7

If y = 7x

when y = 12

x = 12/7
