Answer:
-10
Step-by-step explanation:
So to set up the equation, it will be x/-5 = 2.
Then, you multiply (because it is the inverse of dividing) 2 by -5, and you get -10.
5 * 8/45=8/9
8/9 * 3/40=1/15
1/15
The standard form using integers is x + 3y = 0
<em><u>Solution:</u></em>
Given that we have to write the given equation in standard form
The standard form of an equation is Ax + By = C
In this kind of equation, x and y are variables and A, B, and C are integers
Let us convert the given equation to standard form
Given equation is:
Multiply the terms inside bracket with constant outside the bracket in right hand side of equation
Simplify the right hand side of equation
Move the 3 from R.H.S to L.H.S
Move the terms from R.H.S to L.H.S
Thus the standard form is found
Answer:
3800
Step-by-step explanation:
Variables:
O - Original cost
N - New cost
c - change factor
Step 1:
Recognize that if something decreases by 19%, it is worth 19% <em>less</em>
This means that the new price, fractionally, is 100% - 19% = 81%
So we can use c as 0.81 (81/100)
Step 2:
Write an equation to represent what is happening
N = O * c
Step 3:
Sub in what we know
3078 = O * 0.81
Step 4:
Rearange and solve
O = 3078 / 0.81 = 3800
