One class collects 8 1/4 pounds of recyclable materials. Another class collects 1 1/2 times as many pounds as the first class. How many pounds of recyclable materials do the two classes collect altogether?
Answers
Answer:
20.625 pounds
Step-by-step explanation:
8 1/4 = 8.25 pounds
1 1/2 of 8.25 = 12.375 pounds
8.25 + 12.375 =
20.625 pounds
Example:
8 1/4 x 1 1/2 and that is 12.375 then you add 8 1/4 and that should be 20.625

If it is to the negative power, you live the decimal point to the left (if positive, move to the right). In the case we move the decimal point 5 places to the left of 7. This results in .00007.
11 = 1 + 3r + 2r
I really need help with this!!
Answers
Answer:
r = 2
Step-by-step explanation:
I'm assuming we're finding r
11 = 1 + 3r + 2r
Add up the numbers with r
11 = 1 + 5r
Subtract both sides by 1
11 = 1 + 5r
-1 -1
10 = 5r
Divide both sides by the coefficient, 5, to isolate the variable, r
10/5 = 5r/5
r = 2
Step-by-step explanation:
11=1+5r
11-1=5r
5r=10
r=10/5
r=2

On Friday, Marvin sold 4 suits that had a mean sale
price of $125. On Saturday, he sold 6 suits that had
a mean sale price of $140. What was the mean sale
price, to the nearest dollar, for all 10 of the suits he
sold on Friday and Saturday?
A. $130
B. $132
C. $133
D. $134
Answers
Answer:
C.$133
Step-by-step explanation:
You have to add all numbers then divide by how many numbers there are.
So, in this case, you must add 125 and 140 to get 265
Then you must divide by 2 since there are 2 numbers
265/2 = 132.5
Round to the nearest dollar
The final answer is $133

(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.
Answers
[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.
