Yes 90 is 1/10 of hundred
Answer:
4 lb
Step-by-step explanation:
Subtracting 4 lb from 18 lb yields 14 lb, the weight of the backpack without math book: 18 lb - 4 lb = 14 lb
The math book weighs 4 lb.
Answer:
The length of a side of the base is
Step-by-step explanation:
we know that
The volume of a rectangular prism is equal to
where
B is the area of the base of the prism
h is the height of the prism
we have
Substitute the values and solve for B
Remember that the base is a square
so
Hello.
Let's solve the absolute value inequality.
In order to do that, let's imagine that |3x-4| is positive.
Since the absolute value of |3x-4| is 3x-4, we write 3x-4 and solve:
Now, move -4 to the right, using the opposite operation:
Add:
Divide both sides by 3:
However, this is only 1 solution.
Let's imagine that |3x-4| is a negative number.
So, the inequality looks like so:
Move 4 to the right:
Divide both sides by -3:
Therefore, the solutions are
Note:
If we divide both sides of an inequality by a negative number, we flip the inequality sign.
I hope this helps you.
Have a nice day.
Answer:
Correct choice is A
Step-by-step explanation:
The line divides the coordinate plane into two semiplanes (top and bottom).
The inequality represents the region of all points (x,y) (including line ) which coordinates satisfy the inequality Actually, this region is top semiplane (red region).
The inequality represents the region of all points (x,y) (including line ) which coordinates satisfy the inequality This region is exactly bottom semiplane (blue region).
These two semiplanes intersect by line
All another options contain some inequalities that do not include the line
