Answer:
x=10 or x=-4
Step-by-step explanation:
|x-3|=7
There are two solutions, one positive and one negative
x-3 = 7 and x-3 = -7
Add 3 to all sides
x-3+3 = 7+3 x-3+3 = -7+3
x = 10 x = -4
Distance divided by time is speed. To find the rate of speed, divide 40 yards by 4.24 seconds which is approximately 9.43 yards per second. 9.43 yards per second is the rate of speed.
The percent of the 7th graders that are in favor of school uniforms is 42.857% which can be rounded as 42.9%.
The survey results show there are a total of 112 7th-grade students and from this total, the number of students that support school uniforms is 48.
Let's calculate the percentage 48 represents:
- x = 48 x 100 / 112
- x = 4800 / 112
- x = 42. 857
This means the percentage of 7th graders that support uniforms is 42.857% which can be rounded to
