3 over 1 + 6 over 60
[3 over 1 × 60 over 60] + 6 over 60
180 over 60 + 6 over 60 ➡ 186 over 60
186 over 60 ➡ 31 over 10
Then we divide 31 from 10 which give you the quotient of 3.1..
(((Meaning ➡ '"3.1" would be your answer)))
Answer:
Associative property of addition
Step-by-step explanation:
its the same order only the () move
If its 21 inches then rounding to the nearest who should be 21 inches
Let's solve this system of equations through substitution.
We have these two equations.
-7x-2y=14
6x+6y=18
Now let divide the second equation by 6.
6x+6y=18 ----> x+y=3
Next, let us move y to the right side of the equation.
x+y=3 -------> x=3-y (x equals 3-y)
Because we found out that what x is in terms of y, we can input that in for every instance of x in this equation below.
-7x-2y=14 becomes -7(3-y)-2y=14 (Why? Because x equals 3-y!)
We have a one variable equation now and can solve for y.
-7(3-y)-2y=14
-21+7y-2y=14
5y=35
y=7
Plug in 7 for y in any equation to find x.
x+y=3
x+7=3
x=-4
answer: x=-4, y=7
