**Weegy:** A boat travel in 3 hours at 65 miles per hour is 195 miles far. 3 hours * 65 miles/hour = 195 miles

**User:** 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 _____.

**Weegy:** If y is 5 when x is 2.5 and y varies directly with x, y is 20 when x is 10. 5/2.5 = y/10 2.5y = 50 y = 50/2.5 y = 20

**User:** What is the equation of the line, in standard form, that passes through (4, -3) and is parallel to the line whose equation is 4x + y - 2 = 0

**User:** Goofy Golf ticket prices for kids under 12 years of age increased from $4.00 to $6.00 this year. What is the percent of increase in the tickets

**Weegy:** The percent of increase in the Goofy Golf ticket prices is 50%

**User:** What is the equation of the line, in slope-intercept form, that passes through (3, -1) and (-1, 5)?

**Weegy:** The equation of the line, in slope-intercept form, that passes through (3, -1) and (-1, 5) is y = -3/2x + 7/2

**User:** If the first equation is multiplied by 3 and then the equations are added, the result is _____.
3x + y = 3
x - 3y = -2

**User:** Alfonso is 8 years older than Ashley. Five years ago Alfonso was three times as old as Ashley. How old is Ashley now?

**User:** 3(2x - 3) + 4(2 - x) = 0

**Weegy:** (2x - 1)(x + 5) = 0; 2x - 1 = 0; 2x = 0 + 1; 2x = 1; x = 1/2; x + 5 = 0; x = 0 - 5; x = -5; the solution set is (1/2, -5)

**User:** Find the thirtieth term of the following sequence.
-6, -4, -2, 0, ...

**Weegy:** 32 is 20th term of the following sequence. -6, -4, -2, 0.

**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 ...

If the first equation is multiplied by 3 and then the equations are added, the result is 10x = 7.

3x + y = 3 multiply 3 on both sides:

9x + 3y = 9 (equ. 1)

x - 3y = -2 (equ 2)

adding up equations 1 and 2 the result is:

10x = 7
