Answer:
The Zabato's number is 2.
Step-by-step explanation:
Let the number = x
Given that:
Three times the sum of the number and ten is the same as eight times the number.
According to the given condition:
3x + 10 = 8x
Simplifying by transferring terms with x on left side and others on right side
3x - 8x = -10 (Sign of transferred terms is changed)
-5x = -10
Dividing both sides by -5
-5x/-5 = -10/-5
x = 2
So the Zabato's number is 2.
Proof:
3x + 10 = 8x
Putting value of x
3(2) + 10 = 8 (2)
6 +10 = 16
16 = 16
Hence proved.
I hope it will help you.

Answer:
Step-by-step explanation:
For this exercise is necessary to remember the following formula:
Where "V" is the speed, "d" is the distance and "t" is the time.
In this case you must solve for the time, then:
Based on the information provided in the exercise, you can identify that:
Therefore, knowing this, you can make the substitution into the formula .
Through this procedure you get that the equation that can be used to find the amount of hours "h" that it will take Sandra to drive "m" miles at her constant speed, is:
Answer: 2730 tiles (Approx)
Step-by-step explanation:
Since, The side length of each side = 25
According to the question the shape of the tile is square.
Thus, the area of one tile = 25 × 25 = 625
Also, we need to tile a kitchen measuring 102 ft. by 18 ft
Thus, the area of the room in which we have to tile = 102 × 18 = 1836 = 1836×30.48 × 30.48 = 1705699.8144
Thus, the total number of the tiles = the area of the room in which we have to tile / the area of one tile =
Since, we must take 2730 tiles to tile the kitchen.
