PLEASE help with 7th grade math work! Thank-you. Show work please.?
Hi there, I'm sure you'll appreciate that it's not very easy to draw a graph in this answer, but I'll do my best to describe it. The y axis should be the cost, and the x should be the number of t-shirts. The graph would meet the y axis (up and down axis) at 20, as the company is charging $20 before dealing with the number of t-shirts wanted. As each t-shirt is $2, the line would increase by 2 on the y axis for every 1 you move along on the x axis (side to side). If you drew the graph, you would look up 25 on the x axis, and it should give you the answer. The other way to do this is to work out the equation. So, since n is the number of t-shirts, you can substitue the number of t-shirts in for n. This will give you c = 2(25) + 20; so c = 70 For b), you would use your graph to find $80 on the y axis, and see how far along the x axis this is. The other option is to use the equation again, where c=$80; 80 = 2n +20; 2n = 60; n = 30. I know this is not how you have been taught, but it is quicker and will allow you to check your answers. c) As n is the number of t-shirts, if the equation is c = 2(15) +20, then there are 15 t-shirts. Sophia wants to know the cost of 15 t-shirts. d) The co-ordinates (30,80) will be when there are 30 t-shirts and the cost is $80. This is beacuse the x axis is the number of t-shirts, and the y axis is the cost, and the co-ordinates are written in the form (x,y). Elisa has used these co-ordinates to find the cost of 30 t-shirts I know this is not perfect without showing you a graph and table, but I hope it helps. Take care, x

Please help on 7th grade math problem on pyramids! Thank you!?
Does "slant height" mean the height from the middle of the base to the point at the top? If so then you have a right angled triangle going from the point to the middle of the base then out to the middle of a side. Upright = 16 feet. Bottom side = 20 (that's half of 40) Get the hypotenuse of this and that will be the distance from the middle of a side up the slates to the point of the roof. That's the height of one slate triangle and it's base would be 40. Now you can work out that area and times it by 4 to get the whole area. (I have a slate roof) :-)

I need help with some 7th grade math problems. Please I'm absolutely desperate. Make someones day?
Thank you if you answer! I wish I could like pay you or something. Anyways here's the problems: (xy^4)^3 divided by xy= ? Simplify: (14y)^4 Express the area of this square (shows picture of tiny square with 12d^6e^7 on the side) Express the area of this square (shows picture of tiny square with 7m^6n^9 on the side.) Which expression has the same value as 81h^8k^6? A.) (9h^6k^4)^2 ? B.) (6h^5k^3)^3 ? C.) (9h^4k^3)^2 ? D.) (3h^2k)^6 Simplify using the laws of exponents: 18^3 multiplied by 18^5 Simplify using the laws of exponents: (-9a^4)(2a^7)= ? BONUS: A ball is dropped from the top of a building. the expression 4.9x^2 gives the distance in meters the ball has fallen after x seconds. Write and simplify an expression that gives the distance in meters the ball has fallen after x^2 seconds, and after x^3 seconds. THANK YOU SO MUCH! I CANT EVEN EXPLAIN MY HAPPINESS IF YOU GUYS ANSWERED THESE. I LOVE YOU I LOVE YOU I LOVE YOU!
I am in 7th grade and take math 2 honors at a high school. I have an A-, how will that factor into my high school GPA?
Thanks for the A2A, Ernie! The only person who can answer this is your school counselor. Some schools count high school level classes taken in middle school in your cumulative GPA. Some don’t, as other have mentioned. (Those who don’t generally don’t count those classes toward your graduation requirements, which can cause a problem later on when you run out of math classes to take!) The question is whether or not the class will be listed on your high school transcript. If it is listed, the grade is counted in your cumulative GPA.Frankly, I’m not sure what a class called “Math 2” covers and whether it’s high school level. Usually high school math classes have names like algebra, geometry, trigonometry and calculus, whereas a “Math 2” might be a general math/prealgebra course, even if it is taught at the high school. Again, your school may vary; your school counselor will know for sure.I will mention that if “Math 2” is an algebra or other advanced math course, and if it is listed on your high school transcript, your counselor should explain that in your letters of recommendation or on the school report. If the admissions officers at the schools you are applying to are not familiar with your school, they may assume, like I did, that Math 2 is a non-standard math course, and wonder why you didn’t just take algebra, geometry etc.In terms of how this particular grade will affect your overall GPA, one A- is not going to make much difference. Even if you got all A minuses, your GPA would be strong at about a 3.8/4.0 (unweighted). If your high school weights grades, this honors A- would be worth 4.8/5.0 or 4.8/6.0 (depending on whether honors and AP/IB classes are weighted the same or differently).TL;dr: Don’t worry about it. Just do your best in the hardest classes you can do well in and you’ll be fine.
