Over the last 3 evenings, Huda received a total of 94 phone calls at the call center. The third evening, she received 3 times as many calls as the second evening.
The second evening, she received 9 fewer calls than the first evening. How many phone calls did she receive each evening?
Please answer??
Answer: See explanation
Step-by-step explanation:
Let the number of calls received the first evening be x.
The second evening, she received 9 fewer calls than the first evening. This will be: = x - 9
The third evening, she received 3 times as many calls as the second evening. This will be: = 3(x - 9) = 3x - 27
Then, the expression for each evening can then b put together and solved further as:
x + (x - 9) + (3x - 27) = 94
x + x - 9 + 3x - 27 = 94
5x = 94 + 9 + 27.
5x = 130
x = 130/5
x = 26
First evening = 26 calls
Second evening = x - 9 = 26 - 9 = 17 calls
Third evening = 3x - 27 = 3(26) - 27 = 78 - 27 = 51 calls

The value of y is 225 when x is 50 from the given graph.
What is Coordinate System?Arrangement of reference lines or curves used to identify the location of points in space is called as Coordinate system.
We need to find the value of y when x is fifty.
In the given graph we have to draw a perpendicular line at x =50.
Now we have to check the point where the perpendicular line touches the graph curve.
Take the corresponding value of y.
When x is 50 the value of y is nearly to 225.
Hence, the value of y is 225 when x is 50.

A, B, D
Step-by-step explanation:
The "form factor" in the attached is the difference between the sum of the squares of the short sides and the square of the long side. If that difference is 0, the Pythagorean theorem is satisfied, and the triangle is a right triangle. When the difference is positive, the triangle is acute; negative, the triangle is obtuse.
As you can see, all but the third triangle are right triangles.

BRAINLIEST PLEASE!!!!!!!!!!!!!Sum of 2 numbers is 36. The larger is 3 more than twice the
smaller number, Find the smaller number below.
Answer:
11
Step-by-step explanation:
so we just make a system of equations:
x+y=36
say that x is the larger and y is the smaller
x-3=2y
so we can combine the equations and solve for x and y
re-arrange x-3=2y to be x=2y+3
x+y=36
x=2y+3
insert the value for x into x into x+y=36
2y+3+y=36
3y+3=36
y=11
now insert that back into x+y=36
11+x=36
x=25
Out of the two numbers x and y, 11 is the smaller number

Line A has a slope of -4/3. Line B is perpendicular to Line A. What is the slope of Line B?
Answer:
The answer is 3/4
Step-by-step explanation:
If two lines in perpendicular, then the slope has a relation as slope1 * slope2 = -1. Then if line 1 has slope -4/3 then -4/3 * x = -1, then x = 3/4 which is the slope for the second line.
