You would first multiply two on both sides of the equal sign. This turns your equation into this:
4-m=20
Then, subtract 4 from both sides of the equal sign. This makes your equation this:
-m=16
However, a variable that is alone usually isn't supposed to be negative. To change this, you must change the sign of the m; since you did this to one side of the equation, you must do it to the other. Making your equation finish off like this:
m=-16
Hope I could help! Sorry about the late response.
Answer:
See below in bold.
Step-by-step explanation:
3y - 2x = 9
3y = 2x + 9 Divide through by 3:
y = 2/3x + 3 is the slope-intercept form.
The y intercept is when x = 0:
y = 2/3(0) + 3
= 3.
The y-intercept is at (0, 3).
Answer:
7 trophies for $49.00
5 trophies for $30.00
-----------------------------------
Explination:
It says that she wants to pay no more than 7 dollars for each trophy she buys, which means 7 and less. So we have to multiply 7 x the number of trophies, And if it gives you the excact number or less its correct.
So we multiply
7 x 7 = 49 (The excact number, correct)
9 x 7 = 63 (The price they are selling it at is higher, incorrect)
12 x 7 = 84 (The price they are selling it at is higher, incorrect)
5 x 7 = 35 (Paying less, Correct)
3 x 7 (The price they are selling it at is higher, incorrect)

Its really easy if you put your mind into it! Goodluck <3
Answer:
<em>10a + 10b / 9x - 9y = 2 / 3</em>
Step-by-step explanation:
As we can see;
10 * ( a + b ) / 9 * ( x - y ) ⇒ 10a + 10b / 9x - 9y
This concludes that the top part of this equation is multiplied by 10 and the bottom by 9. To derive the solution, let us do the same with 3 / 5;
10a + 10b / 9x - 9y = 3 * 10 / 5 * 9
And simplify, to recieve;
10a + 10b / 9x - 9y = 30 / 45 = 6 / 9 = 2 / 3,
<em>Answer: 10a + 10b / 9x - 9y = 2 / 3</em>
