Answer:
Solve for z by simplifying both sides of the equation, then isolating the variable.
Exact Form:
z = 63/2
Decimal Form:
z = 31.5
Mixed Number Form:
x = 31 1/2
First, change the decimal to a fraction by putting it over 1000:
Now find a common denominator of 625 and 1000. The simplest to find and divide by is 5. So begin by dividing them each by five until you have a completely simplified fraction:
The answer is

Answer:
20 is 80% of 25
Step-by-step explanation:
We assume, that the number 25 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 25, so we can write it down as 100%=25.
4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.
5. Now we have two simple equations:
1) 100%=25
2) x%=20
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=25/20
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 20 is what percent of 25
100%/x%=25/20
(100/x)*x=(25/20)*x - we multiply both sides of the equation by x
100=1.25*x - we divide both sides of the equation by (1.25) to get x
100/1.25=x
80=x
x=80

Answer:
y=-3x-2
Step-by-step explanation:
The slope-intercept form is y=mx+b
where m is slope and b is y-intercept.
Substitute m=-3 and point (x,y)=(1,-5) into the equation:
-5=-3(1)+b
-5=-3+b
b=-5-(-3)=-5+3=-2
Therefore, the required equation:
y=-3x-2
