Answer:
The Original Number is 36
Step-by-step explanation:
Given:
y is the number in units place
x is the number in tens place
Original Number = 
is equation 1
Now after interchanging the digits
New number = 
New Number = 27 + Original Number
Substituting Valus in above equation we get.

let this be equation 2
Adding equation 1 and 2 we get

Substituting value of y in equation 1 we get

x=3 and y=6
Original Number =
For this case what we can do is the following rule of three:
152 -----> 2
x --------> 20
We clear the value of x:
x = (20/2) * (152)
x = 1520 tons
Answer:
in order to locate 20 ounces of diamonds the company needs:
x = 1520 tons of rock
Hello! To solve this equation, first, add 5g to both sides. There are many instances where you would add, but because -5g is negative, you add. You do this to cancel that out, and get the integer without the variable on the right by itself. When you do this, you get 7g + 9 >= -12. Now, subtract 9 from both sides to get the 7g by itself. After that, you get 7g >= -21. Now, divide each side by 7 to isolate the variable. -21/7 is -3. There. g >= -3.
Answer:
5 cm
Step-by-step explanation:
Here, we want to get the length of each box edge
Let the length be s
Mathematically, the volume of a cube is s^3
Thus;
s^3 = 125
s^3 = 5^3
s = 5 cm
