Answer:
54
Step-by-step explanation:
3x -(7-x) = 29 remove the parens
3x - 7 + x = 29 simplify
4x -7 = 29 add 7 to both sides of the equation
4x = 36 divide by
x = 9
then 6x = 6 * 9 = 54

Y=mx+b is The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
1 hr = 60 min
1/6 hr = (60/6) min = 10 min
so the bell rings every 10 min. Since 1 hr = 60 min, this means that 2/3 of that is 40 min. So the bell will ring 4 times (divide 40 over 4) in the next 2/3 of an hour, which is the same as saying "the bell will ring 4 times in the next 40 minutes"
Answer: 4 times
