Answer:
Step-by-step explanation:
X=9
Answer:
The answer in the procedure
Step-by-step explanation:
Let
x ----> the dog walking hours
y ----> the car washing hours
we know that
The system of linear inequalities is equal to
-----> inequality A
-----> inequality B
Solve the system of inequalities by graphing
The solution is the shaded area
see the attached figure
Two possible combinations of hours are
(10,10) and (0,9)
<em>Verify</em>
For (10,10)
Substitute the value of x and the value of y in both inequalities
<em>Inequality A</em>
-----> is true
<em>Inequality B</em>
----> is true
therefore
(10,10) is a possible solution
For (0.9)
Substitute the value of x and the value of y in both inequalities
<em>Inequality A</em>
-----> is true
<em>Inequality B</em>
----> is true
therefore
(0,9) is a possible solution
Answer:
C. 3
Step-by-step explanation:
2/5 x = 6/5
Multiply each side by 5/2 to isolate x
5/2 * 2/5 x = 6/5 * 5/2
x = 6/2
x=3
Step-by-step explanation:
1: Solve one Equation for one of the variables
2: Substitute (plug-in) this expression into the other equation and solve
3: Resubtitue the value into the original equation to find the corresponding variable
Step-by-step explanation:
You said:
'25% of the people = 60 people "
' 25% ' means 0.25
'of ' means ' times'
So people (0.25) x (the people) = 60
the people=60/0.25
the people=6000/25
the people=240
