9-x/5=3. Solve for x

kari74 [83]

Answer:

$\boxed{\boxed{\sf x=-6}}$

Step-by-step explanation:

$\sf \cfrac{9-x}{5}=3$

$\sf \cfrac{5\left(9-x\right)}{5}=3\times \:5$

$\sf 9-x=15$

$\sf 9-x-9=15-9$

$\sf -x=6$

$\sf \cfrac{-x}{-1}=\cfrac{6}{-1}$

$\sf x=-6$

Graph the function.<br> f(x)= 3/5x}=-5

Start at negative 5 since that’s your y-intercept.
Since 3/5 is your slope and slope equals rise over run you go up 3 units and go right 5 units.

Answer:

0.4016%

Step-by-step explanation:

Estimated Value = 3,500 people , Exact attendance = 3486 people

We can see that there is a Percentage decrease . So we will apply the formula.

%Decrease = Old Value - New Value /Old Value × 100%

%decrease = 14/3486 %

%Decrease = 0.4016% (Answer)
