Step-by-step explanation:
Annie = x
Brianna = y
Carly = z
Now,
x + y + z = 105 ...(1)
Carly has sold ten more than three times Brianna's sales.
z = 10 + 3y ...(2)
Brianna sold five more than Annie.
y = 5 + x ...(3)
Now,
z = 10 + 3y
z = 10 + 3(5 + x)
z = 10 + 15 + 3x
z = 25 + 3x
Now,
x + y + z = 105
x + (5 + x) + 25 + 3x = 105
5x + 30 = 105
5x = 105 - 30
5x = 75
5x/5 = 75/5
x = 15
So,
y = 5 + x
y = 5 + 15
y = 20
Now,
z = 25 + 3x
z = 25 + 3(15)
z = 25 + 45
z = 70
Thus,
Annie Sold 15 boxes
Brianna Sold 20 boxes
Carly Sold 70 boxes
Answer:
Depth=3.18cm
Step-by-step explanation:
V=πr2h
1LITRE=1000CM3
v=1000cm³
1000cm3=3.142×10²×Depth
Depth= 1000/3.142×100
Depth=3.18cm
<span>Let's start with basic definitions:
1 inch-----0.0833333 ft
If 0.375 Ft- represents 0.25 inches
then 1 foof-x inches
0.25 inches x 1 ft / 0.375 ft: 0.66666666666667 (2/3) inch
1 foot is represented by 2/3 of an inch</span>
Answer:
-80
Step-by-step explanation:
We have to do the parentheses first because it's part of PEDMAS.
-2x-5= 10
Next, we take 10 times -8
-8 x 10= -80
There you go! Hope this helps!
