Answer:
$45 in all
Step-by-step explanation:
30 + 15 = 45 that is me
We need to represent the numbers of calls symbolically:
Third evening: x calls
First eve: x-6 calls
Second evening: 3x calls
Find x. Add up these three numbers x, x-6 and 3x and equate your sum to 79:
x+x-6+3x = 79. Then 5x=79+6, or 5x = 85. Thus, x = 17.
17 calls on the 3rd night,
17-6 calls on the 1st night, and
3(17) = 51 calls on the 2nd night.
Check! Add together 17, 11 and 51. Do these add up to 79? Yes.
1/4(8/3 • 9) - 3
=3
I think this is probably the answer
The length of the line segment with endpoints at (0, 3) and (-6, -5) is 10 units
<h3>What is an equation?</h3>
An equation shows the relationship between two or more numbers and variables.
The distance between two points A(x₁, y₁) and B(x₂, y₂) on the coordinate plane is:

The line segment have endpoints at (0, 3) and (-6, -5). Hence:
Length = √[(-5-3)² + (-6 - 0)²] = √(8² + 6²) = √100 = 10
The length of the line segment is 10 units
