Answer:
12 = u
Step-by-step explanation:
52=5u-8
Add 8 to each side
52+8=5u-8+8
60 = 5u
Divide each side by 5
60/5 = 5u/5
12 = u
Andrew and Michael are 15 miles apart. If they walk towards each other, they meet in 3
hours. If they both walk in the same direction, Michael overtakes, Andrew in 8 hours.
How fast does each boy walk?
Answer: Andrew - 1.875 Michael- 3.125
Step-by-step explanation:
If Andrew overtakes in 8 hours, we can divide 15 miles by 8 to see how many miles per hour he goes.
15/8 = 1.875
Then we can multiply 1.875 by 3 to see how much he traveled while walking towards Michael.
1.875*3=5.265- the distance he traveled
Now subtract that by 15 to see how many miles Michael walked.
15-5.625=9.375
That means Michael walked 9.375 miles.
Divide 9.375 by 3 to see how many miles he walked per hour
9.375/ 3 = 3.125

Two radio stations are playing this week's #1 hit song. One radio station plays the song every 18 minutes. The other radio station plays the song every 24 minutes. Both stations play the song at 3pm. How many minutes will pass before they play the same song again. (Only write the minutes.)
Answer:
1) 12
2) 72
Step-by-step explanation:
1) The GCF of 36 and 24 is 12. So, each child would get 3 prizes and 2 balloons.
2) The LCM of 18 and 24 is 72. When the first radio station is playing the song for the fourth time, the second radio station will play the song for the third time. This will happen 72 minutes after they both play it for the first time.
Answer:
1. 12 children
2. 72 minutes
Step-by-step explanation:
1. Find the GCF of 36 and 24, which is 12
2. Find the LCM of 18 and 24, which is 72

Answer:
x=5/3, and x=-1
Step-by-step explanation:
The absolute value sign makes anything inside of it positive. So there are two possible x values for this problem. When we open the absolute value brackets we need to create two different equations. 3x-1=4, and 3x-1= -4. Solving these two equations we can find two possible values of x. x equals 5/3, and -1.

(08.01) The graph shows two lines, Q and S.
A coordinate plane is shown with two lines graphed. Line Q has a slope of one half and crosses the y axis at 3. Line S has a slope of one half and crosses the y axis at negative 2.
How many solutions are there for the pair of equations for lines Q and S? Explain your answer.
[tex]\huge\blue{ANSWER}:—[/tex]
A solution for a pair of lines means that they are equal to each other. This occurs when they instersect. Since the lines have the same slope, but are not the same line, they are parallel, so they will never intersect. This means there are zero solutions.
Hope this helps!The provided set of equations for the lines Q and S have no solutions.
What is the Slope of a line?The slope of a line is a measure of how steep the line is and is defined as the change in y divided by the change in x between any two points on the line. In other words, the slope is the ratio of the vertical distance between two points on the line to the horizontal distance between them.
What are parallel lines?Parallel lines are two or more straight lines that are equidistant from each other at all points and do not intersect, no matter how far they are extended in both directions. Parallel lines are often denoted by a double vertical line symbol (||) drawn between them.
In the given information:
Line Q crosses the y-axis at 3 and has a slope of one-half.
Therefore,
x=0 and y= 3
Straight line equation: y= mx + c
where m is the line's slope
The values in this equation should be replaced.
y= mx + c
3= (1/2) ×0+c
3 = c
y= (1/2) x + c
Line S crosses the y axis at -2 and has a slope of one half.
Thus, the c will be negative.
After that, the line's equation is y = (1/2) x - 2.
Use the equation to plot the graph.
So,
Line Q and Line S are parallel lines.
Due to the fact that it won't intersect, there is an equation.
Thus, the provided pair of equations for lines Q and S have no solutions.
