Step-by-step explanation:
The difference of the given expressions is 274x - 4325.
The given expressions are 38x+215 and 312x−4110.
What is the subtraction of expressions?To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.
Now, 38x+215 is subtracted from 312x−4110
That is, 312x−4110 - (38x+215)
= 312x-38x-4110-215
= 274x - 4325
Therefore, the difference of the given expressions is 274x - 4325.

Step-by-step explanation:
The area of the triangle will be A = (1/2) y₁(x₂ - x₁). Then the correct option is B.
What is the area of the triangle?Assume 'h' is the height of the triangle and 'b' be the base of the triangle. Then the area of the triangle is given as,
A = (1/2) × h·b
The coordinates of the triangle will be (x₁, y₁), (x₂, y₂), and (0, 0).
The length of the base of the triangle will be given as,
Base = (x₂ - x₁)
The height of the triangle is given as,
Height = (y₂ - 0) or (y₁ - 0)
Height = y₂ or y₁
The area of the triangle will be given as,
A = (1/2) × (x₂ - x₁) × y₁
A = (1/2) y₁(x₂ - x₁)
The area of the triangle will be A = (1/2) y₁(x₂ - x₁). Then the correct option is B.

A plumber charges his customers $25.70 per hour, h, plus a $54.50 service fee.On Tuesday,he earns $118.75 for fixing Mrs.Goodwill's sink. How long does it take the plumber to fix Mrs.Goodwill's sink
Answers
Answer:
2.5 hours
Step-by-step explanation:
Given that :
Charge per hour = 25.70
Service fee = $54.50
If total earning = 118.75 ; how many hours did it take to fix the sink?
Let number of hours = x
Total earning = service fee + (charge per hour * number of hours)
118.75 = $54.50 + (25.70x)
118.75 - 54.50 = 25.70x
64.25 = 25.70x
x = 64.25 / 25.70
x = 2.5
Hence, it took 2.5 hours to fix the sink
