Mary covered her kitchen floor with 10 tiles. The floor measures 6 feet long by 5 feet wide, The tiles are each 3 feet long and w feet wide. Write an equation to represent the situation.

Answers

Number of tiles used forcovering the kitchen floor = 10
Area covered by the floor = 6* 5 feet^2                                              
                                         = 30 square feet

Length of each tiles = 3 feet
Width of each tiles = w feet
Area covered by each tiles = 3w square feet
Then the equation can be written as
3w * 10 = 30
30w = 30
 w= 30/30    
    = 1 feet

So the width of each tiles is 1 feet.I hope the procedure is clear enough for you to understand. The equation to determine the solution is
10 *3w = 30
There are 10 tiles used and the area covered by each tiles is 3w. Also the area of the floor is 30 square feet. All those information's have been used to get to the equation.

Explanation: Keep dividing by 2

Jim bought 2 packs of batteries from a store. The price of each pack was the same. After he bought the batteries, his account balance showed a change of −$23.94. What would have been the change to Jim's account balance had he only bought 1 pack of batteries from the store?−$21.94 −$11.97 $11.97 $21.94

Answers

Hello,

The correct answer is B) -$11.97

Hope this helps!!!! :)

**(Vanessa)**

Final answer:

If Jim had purchased only one pack of batteries, the change to his account balance would be -$11.97.

Explanation:

This problem describes a mathematical scenario related to buying and pricing. Given that Jim bought 2 packs of batteries for -$23.94, we can infer that this is the total cost for both packs. Therefore, to find the cost of one pack, you will simply divide the total cost by the number of packs.

To do this, −$23.94 should be divided by 2. Using a calculator, this division equals −$11.97. Therefore, the change to Jim's account balance if he had only bought 1 pack of batteries would have been −$11.97.

Solve this k/3+4-2k=-9k

Answers

k/3 + 4 -2k = -9k
First you add 9k to both sides
k/3 + 4 -2k = -9k
            +9k   +9k
k/3 + 4 + 7k = 0

Now subtract 4 from both sides
k/3 + 4 + 7k = 0
        -4           -4
k/3 + 7k = -4

Now multiply 3 by both sides
k/3 + 7k = -4
x3     x3    x3
k +21k = -12

Now add k + 21k
22k = -12

Now divide both sides by 22
22k = -12
-----    -----
 22      22
k = -6/11

Answer:

25.04\,* \,3.005=75.24520

Step-by-step explanation:

Multiplication refers to repeated addition of same number .

For example 2 * 3 means 3 is added 2 times or we can say 2 is added 3 times .

Here, we need to find product of 25.04 and 3.005 .

To solve : 25.04\,* \,3.005

First, we will solve 2504* 3005

2505* 3005=7524520

Now number 25.04 has 2 decimal places and 3.005 has 3 decimal places, so  will shift decimal  2 + 3 = 5 places towards left of number 7524520 .

So, 25.04\,* \,3.005=75.24520

3-5(x+4)=8(2x-3) how to solve this equation

Answers

Answer:3

Step-by-step explanation:

Final answer:

The solution to the equation 3-5(x+4)=8(2x-3) is x = 1/3. The solving process involves distributing, collecting similar terms, isolating variables, and finally simplifying.

Explanation:

To solve the equation 3-5(x+4)=8(2x-3), we need to follow a few steps:

  1. Start by simplifying both sides of the equation. This step would involve the use of the distributive property.
  2. Distribute 5 into the parenthesis on the left side to get 3 -5x -20. In the same way, distribute 8 into the parenthesis on the right side to get 16x -24.
  3. The simplified equation would then be: -5x -17 = 16x -24.
  4. Next, get all the x terms on one side (by adding 5x to both sides) and the constants on the other side (by adding 24 to both sides). This gives us 21x = 7.
  5. Finally, to isolate x, divide both sides by 21 to get x = 7/21, which simplifies to x = 1/3.
