I am divisible by 5.

So your ones digit is 0 or 5

I am an even number.

So your ones digit is 0. We fill that in.

_ _ 0

My tens digit is 1.

So we fill that in.

_ 1 0

My tens digit is greater than my ones digit.

Well, of course 1 is greater than 0. We didn't need to be told that.

I have only one odd digit.

Since the 1 is odd, the hundreds digit is even, 2,4, or 8

I am less than 400.

So your hundreds digit is 2. Fill that in and we're done.

2 1 0

My hundreds digit is greater than my tens digit.

Of course 2 is greater than 1, we didn't need to be told that.

I am divisible by 3.

Of course 210 is divisible by 3. We didn't need to be told that.

Too much information!

Which value of x makes the following equation true? 3(x - 4) = -2x + 18 A. 7 B. 9 C. 10 D. 6

Answers

3(x - 4) = -2x + 18

Basically, you need to solve for x

3(x - 4) = -2x + 18
3x - 12 = -2x + 18
+2x +2x

5x - 12 = 18
+12 +12

5x = 30
x = 6

Answer: The value that makes this equation true would be 6.

3x-12=-2x+18 (distributive property)
Now add two x to both sides.
5x-12=18
Now add. 12 to both sides.
5x=30
Divide both sides by 5.
x=6

A piece of licorice is to be cut into 10 equal size pieces . If the length of the piece of licorice is 2/3 yard, how long will each piece of licorice be?

Answers

The first thing to do is turn this into an equation:
2/3 ÷ 10

10 as a fraction is 10/1
2/3 ÷ 10/1 =

Fractional division is just fractional multiplication after switching the numerator and the denominator of the second fraction:
2/3 X 10/1

Fractional multiplication is simply multiplying the numerators by each other, and the denominators by each other:
2 X 10 = 20
3 X 1 = 3

20/3

Each piece of liquorice will be 20/3 or 6 2/3 of a yard long.

A small university has six identical parking lots that hold a total of 1110 cars. Write an equation to find the number of cars each parking lot can hold.

Answers

Each parking lot can hold 185 cars.

What is division?

Math operations include division as one of its types. This technique involves splitting the phrases or numbers into the same amount of components.

Let's denote the number of cars each parking lot can hold as x.

Since there are six identicalparking lots, the total number of cars they can hold is 6x.

According to the problem, the total number of cars that can be parked in these six lots is 1110.

So we can write:

6x = 1110

This equation relates the number of cars each parkinglot can hold (x) to the total number of cars that can be parked in all six lots (1110).

To solve for x, we can divide both sides of the equation by 6:

x = 185

Therefore, the required number is 185 cars.

Because they are all identical, they share the same amount of cars. So the equation would be 6x=1110
