Answer:
solution :
x = 4
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
5*(x-10)-(30-15*x)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
5 • (x - 10) - (30 - 15x) = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
20x - 80 = 20 • (x - 4)
Equation at the end of step 3 :
20 • (x - 4) = 0
Step 4 :
Equations which are never true :
4.1 Solve : 20 = 0
Step-by-step explanation:
Answer:

Step-by-step explanation:
By definition, the absolute error is defined as:

Where:
: is the error
: is the approximate value
: is the exact value
In this problem the approximate value was 100 and the exact value was 75. Then we substitute these values in the formula to find the error.

A2= 1
a3=-3
a4=-7
the common difference is -4
Answer:approximately 65.6
Step-by-step explanation:
Here we want to have x on one side of equation so,
we put number 5 on right side of equation:
abx=5
then we divide both sides by ab to obtain x on left side:
Result:
x=<u />
