Use each of the digits 2,3,5, and 8 once with any combination of + ,- ,· ,÷, or ( ) to write an expression with a value of 104. You can repeat operations, but not numbers.
Answers
(5*2+3)*8=104 because 5*2 equals 10 and 10+3 equals 13 and then 13*8 equals 104

Laura walks 3/5 mile to school each day. Isaiah's walk to school is 3 times as long as Laura's. How far does Isaiah walk to school each day?
Answers
In this question, it is important to understand the words of the problem and then note down the details already provided in the problem. This will make the solving of this problem easier.Now coming to the details already given. Distance walked by Laura to reach school each day = 3/5 mile Distance walked by Isaiah to reach school is 3 times that of Laura and it is already given in the question. Then The distance walked by Isaiah to reach school each day = (3/5) * 3 = 9/5 = 1 4/5 So Isaiah walks a distance of 1 4/5 miles each day for reaching school. I hope that the procedure of doing such problems is clear to you and yiou can attempt such problems in future without needing any help.
If you would like to know how far does Isaiah walk to school each day, you can calculate this using the following step:
Isaiah's walk: 3 times as long as Laura's Laura's walk: 3/5 mile
3 * 3/5 mile = 9/5 mile = 1 4/5 mile
The correct result would be 1 4/5 mile.

PLEASE HELP 20 POINTS!The sum of the x- and y-intercepts of the graph of 5x+3y = k is 32 5. Find the length of the line segment joining the x- and y-intercepts.
Thank you so much! I literally have no idea how to do this.
Answers
Sure you do.
What is the x-intercept ? It's the point where the graph crosses the x-axis. But y=0 at every point on the x-axis ! So the x-intercept is the point where
5x + 3(0) = k 5x = k x = 0.2 k
Similarly ... What is the y-intercept ? It's the point where the graph crosses the y-axis. But x=0 at every point on the y-axis ! So the y-intercept is the point where
5(0) + 3y = k 3y = k y = k/3
The sum of the x- and y-intercepts is 32.5 . 0.2k + k/3 = 32.5 Multiply each side by 5 : k + 5k/3 = 162.5 Multiply each side by 3 : 3k + 5k = 487.5 8k = 487.5 Divide each side by 8 : k = 60.9375
The x-intercept is (0.2k, 0) = the point (12.1875, 0) .
The y-intercept is (0, k/3) = the point (0, 20.3125) .
Those are the two points. Now it wants you to find the distance between them. Do you remember how to find the distance between 2 points ?
Find the (difference of their x-values) and square it. Find the (difference of their y-values) and square it. Add the two squares together. Take the square root of the sum. That's the distance between the points.
(12.1875)² + (20.3125)² = the square of the distance.
If you don't get 23.688 for the distance, then check your arithmetic.
