Answer:
37.5 %
Step-by-step explanation:
decrease in price=72-45=27
% decrease=27/72 ×100=75/2=37.5
To solve this, you must put the equation in slope-intercept form, which is y=mx+b.
To do this, isolate y.
First, subtract 3x from both sides.
3x + 9y = -9
3x + 9y - 3x = 9y
-9 - 3x = -9 - 3x
9y = -9 - 3x
Now, divide both sides by 9.
9y = -9 - 3x
9y / 9 = y
-9 / 9 = -1
-3x / 9 = -0.33x = -1/3x
y = -1 - 1/3x
In y = mx + b form:
y = -1/3x - 1
In slope intercept form, m is the slope.
In our answer, -1/3 is m, so it is the slope.
So the final answer is that the slope is -1/3.
Hope this helps!
1.2 A$ = 1 US$
22 A$ = x US$ Cross multiply
1.2*x = 22 * 1 Divide by 1.2
x = 22/1.2
x = 18.3 US $
Mixed number is just saying 3(denominator) times 1 (whole #) plus 2(numerator) which would equal 5 its like a cartwheel :)
Use the formula distance = rate x time
The rate is 20 m/s The time is 2 hours, which can be converted to seconds 1 hr = 60 min 1 min = 60 sec.
1 hr = 60 (60) = 3600 sec.
The distance traveled will be 20 m/s is 3600 s
