Answer:
B. 60
Step-by-step explanation:
30 is 1/2 of 60
X and 75° are both on the same line, so that makes it same side interior anglies I believe. A straight line is 180° so you set up your equation. 180=x+75. Subtract 75 from both sides. x=105°
Answer:
the number was probably multiplied by 3 and then divided by 2 which is 18

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
