For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
We now write the equation that models the problem:

From here, we clear the value of x.
We multiply both sides of the equation by 2:

We subtract 30 on both sides of the equation:

Answer:
The value of the unknown number is given by:

Answer:
The answer is D. x= 4
Step-by-step explanation:
The angles are congruent so
2.3x +25 = 5.8x + 11
2.3x - 5.8x = 11 - 25
-3.5x = -14
x = 14/3.5
x = 4.
Answer:
To get answer A, Dave took 47*5 = 235
Step-by-step explanation:
There are 147 containers that contain 5 gallons each. We need to multiply to find the total number of gallons.
total number of gallons = containers * number of gallons per container
= 147* 5 gallons per container
=735 gallons
To get answer A, Dave took 47*5 = 235
