<h2>
Answer:</h2>
First day - 25 calls
Second day - 16 calls
Third day - 75 calls
<h2>
Step-by-step explanation:</h2>
You need to set variables and create system of equations first.
First evening= x
Second evening= y
Third evening = z
x+y+z=116
z=3x
y=x-9
Now you plug in the values into the equation x+y+z=116
x+(x-9)+(3x)=116
5x-9=116
5x=125
x=25
You plug in the value of x into the other equations.
x= 25
z= 3*(25)=75
y=(25-9)=16
Rearrange so it corresponds with days...
First day - 25 calls
Second day - 16 calls
Third day - 75 calls
Answer:
(2/3)r=30
r=45cm
Step-by-step explanation:
When trying to find a fraction of something, multiply to get your answer:
(2/3) of r = (2/3)r
The blue ribbon can be represented by both 30cm and (2/3)r cm:
(2/3)r=30
2r=90
r=45cm
The graphs are attached. Each graph is transformed by a horizontal translation or vertical translation or a reflection.
Answer:
- 1/5
Step-by-step explanation:
Slope of a line passing through two points can be calculated as:
The given points are (-2, -1) and (8, -3). Using the values in above formula, we get:
Thus the slope of the line through the given points is -1/5. So 2nd option gives the correct answer
Answer:
Flip the sign.
Step-by-step explanation:
For example if it was -2<3 youd flip the sign when you get your answer. So it would be -2>3 except itd be your answer. I just made this problem up but flip the sign!
