1)
||x|-4|= |x-1|
1st step = separate the equation into 2 possible equations
2nd step = solve the equations
|x|-4= x-1
x= -3/2
Or
|x|-4= - (x-1)
X= 5/2
2)
Do the same
X= -5/2
X= 7/2
-10(x-7) -3x
= -10x + 70 - 3x
= -13x + 70
The answr is A
Answer:
(1).(C) Commutative property.
(4).(D) 3
(3).(D) 75
Step-by-step explanation:
(1) Commutative property of addition states that if two number p and q are real. Then, it doesn't matter in which order the numbers are added it will provide the same result. i.e.
<em>p + q = q + p</em>
Therefore, -8 + (-15) = (-15) + (-8) is an example of commutative property.
(2) - (q+14) = (-3) + (-14)
(3) -10 + <em>a </em>+ (-15) = 50
Answer:
No solution
Step-by-step explanation:
7x - 3 = 7 + 7x
Subtract 7x from both sides of the equation.
7
x
−3−7x=7 rewrite as
7x-7x-3=7
-3=7
Answer:
The sample proportion of students who go to their locker at least 3 times each day is 0.403.
Step-by-step explanation:
Sample proportion of students who go to their locker at least 3 times each day.
The sample proportion of students who go to their locker at least 3 times each day is the number of students who do this divided by the size of the sample.
In this question:
137 go to their locker at least 3 times each day, sample of 340 students. So
137/340 = 0.403
The sample proportion of students who go to their locker at least 3 times each day is 0.403.
