Answer: 2.4
Step-by-step explanation:
4/5 x 3 = 2 and 3/5
2 and 3/5 converted into decimal is 2.4
You're welcome!
Hi there!
Thanks for asking for help!
I believe Part A of your answer is the expression: n+2n.
Because that is the answer for Part A, Part B is the answer: "The expression for the bookcases is n+2n because the problem says 'the larger bookcase holds twice as much as the smaller one,' and 'let n represent the amount of books the smaller bookcase holds'.
Since you need to find an expression for the amount both bookcases needs to hold you would add n (capacity of the smaller bookcase) and 2n (capacity of the larger bookcase) together to have an expression that represents the amount both hold.
Part C: 90=3n
I know this is the correct equation based on the expression written above since n+2n=3n, and the problem says "the amount both bookcases hold together is 90 books"
btw, bookcase 1 holds 30 books and the large bookcase holds 60.
Hope this helps you out! :)
Okay, so we know the first triangle is an equilateral and the second is an isosceles. (the lines indicate congruence)
To find x, we have to figure out the other triangle's angles.
Since it is equilateral, all its sides are 60 degrees.
All triangles angles add up to 180. 180/3= 60
To find x we subtract the angle beside it by 180 to find the angle's degree.
180-60= 120. x= 120.
Since it is an isosceles, the last two angles are the same.
Subtract the vertex from 180.
180- 120= 60
Divide that by 2. (since there are two angles)
y= 30 Or choice A. <span />
