<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:
6a
Step-by-step explanation:
AB = √[(3a - -3a)² + (0)²]
⇒ AB = √[(3a + 3a)² + (0)²]
⇒ AB = √[(6a)² + (0)²]
Answer:
-1
Step-by-step explanation:
All of them equal negative one and -1*-1 equals negative 1
3b+5r=2 gallons of cabbage red
1r+7b=2gallons of egplant
1 gallon of cabbage sells for 22 (means 2 gallos is 44)
1 gallon of egplant is 26 (means 2 gallons is 52)
3b+5r=44
r+7b=52
r+7b=52
miinus 7b from both sides
r=52-7b
sub 52-7b for r in othe equestion
3b+5(52-7b)=44
3b+260-35b=44
-32b+260=44
minus 260 from both sides
-32b=-216
divide both sides by -32
b=6.75
r=52-7b
r=52-7(6.75)
r=52-47.25
r=4.75
3blue+5r=2gallons
5+3=8
8units=2gallons
4units=1gallon
1unit=1quart
therefor
1 quart of blue paint is $6.75
1 quart of red paint is $4.75
The plant will be 34 millimeters after 8 months and 118 millimeters after 3 years. I solved this using the formula y=10+3x, where you are solving for y. You would replace x with the number of months and then solve.
