Answer:
Solve 14×1/5=n does not work
Step-by-step explanation:
Assuming you mean
4 ÷ 1/5=n
A Find out how many 1/5s are in 4.
That is correct. We are writing the division problem in words
B Solve 4×5/1=n.
We can copy dot flip
4 * 1/5=n
C Solve 1/4×1/5=n.
We do not flip the first term
D Solve n×1/5=4.
4 ÷ 1/5=n
Multiply each side by 1/5
4 ÷ 1/5 * 1/5=n* 1/5
4 = n*1/5
Answer:
We have the same homework!!!!
hours that passed= 10
Step-by-step explanation:
(1st step)We start with the expression:
(1st)82-0.4x=78
"STARTED at 82 degrees" 82
"Cooling DOWN 0.4 degrees" -0.4
"EACH hour" x
"NOW 78 degrees" =78
(2nd step) We want to get the variable x alone, so we have to do the opposite sign they have, to cancel the number out for it to be 0.
(1st) 82 -0.4x =78
(2nd) -82 ÷-0.4 =78
(3rd)Now, you work out the problem (transfer the numbers from the left to the right). First, you have to do the subtraction sign, not sure why.
(1st) 82 -0.4x =78
(2nd) -82 ÷-0.4 =78
(3rd) 78 -82= -4
-4÷-0.4= 10
X= 10
there you have it!
To make sure this is correct, you do the following.
82 -0.4 x 10
Solve using PEMDAS
-0.4 x 10 = -4
its time to add 82.
82 - 4 = 78
78 is the exact temperature that was said in the problem
Answer:
associative property of addition
Step-by-step explanation:
2p + (3q + 2) = (2p + 3q) + 2
There are no terms that can be combined since there are no like terms
We are using the associative property to move the parentheses from one group of terms to the other.
Well you can automatically eliminate, A, because when you multiply one number that's positive and another number that's negative the result is always going to be negative.
However, when you multiply two negatives the result is always positive!
So, the only ones up there that would result in a positive number is B and C
***D. was not posted so I cannot determine that one!
