Ok so for the first one it’s super simple I’m gonna do it as less complicated so it can help you :)
So first we need to convert the mixed number to an improper fraction
1 4/5 = 9/5
Now we need to reduce the numbers greatest common divisor which is 3
3/5 x 6
Now multiply the numbers
Your answer is 18/5 I hoped this help
Now for the second one
this one is a little more complicated and I don’t know how to make it sound easier so I’m gonna tell you the answer which is 580/21
The last one is the same steps we did for the first one which is 27/20
I hoped this helped you it is a little difficult but you’ll get the hang of it :)
If 8 apples cost a dollar sixty then one apple costs 20 cents. so 20 cents.
Answer:
40n
Step-by-step explanation:
(40+n): The first one is asking to add forty and n, however the question is asking for multiplication so that is not an answer.
(n-40): This one is using subtraction, so this one is an obvious no.
(40/n): This phrase represents division, this could be a possibility because it is the inverse operation, however the numbers need to be reversed.
(40n): Im thinking that you got confused because there was no operation symbol. Whenever a number and a variable are attached without an operation symbol in between, you multiply. So, this is the correct answer.
If 
, all angles would be equal, resulting in similar triangles. So B is right
5 feet is 60 inches. The other side with the two lines is also 17.2 in. The two sides with only one line will each be (60 - 17.2 - 17.2) / 2, because they're equal. That will make both sides with the one mark 25.6 / 2, or 12.8 in.
You can't find the area unless you have the angle of the vertices or the height.
