R = robins cans
s = sara's cans
n = nick's cans
T = total cans
s = 5r
n = 6r
T = 216 = s + r + n
we sub in the first two equations into the first
216 = 5r + 6r + r
216 = 12r
r = 18
sub this back into equations 1 and 2
thus
r = 18
s = 90
n = 108
I'm pretty sure it's 29 . . . A way to remember is that when you multiply a number by ten, add a zero. For example, 34 x 10 is 340. Just add the zero!
Price of movie ticket in Japan is x=7.362$
Price of movie ticket in Switzerland is y=13.652$
Step-by-step explanation:
Let, Price of movie ticket in Japan is x
Price of movie ticket in Switzerland is y
Statement 1 : Total of 79.39$ of three movie ticket in Japan and two movie ticket in Switzerland
We write, 3x+2y=79.39 ( Equation 1 )
Statement 1 : Total of 75.68$ of two movie ticket in Japan and three movie ticket in Switzerland
We write, 2x+3y=75.68 ( Equation 2 )
Solving by method of elimination
Multiplying equation 1 by 2, we get
6x+4y=158.78
Multiplying equation 2 by 3, we get
6x+9y=227.04
Subtracting both the linear equation,
6x+4y=158.78
- 6x+9y=227.04
_______________
0x-5y=(158.78-227.04)
-5y=(-68.26)
5y=68.26
y=13.652$
Replacing value of y in any equation
3x+2y=79.39
3x+2(13.652 )=79.39
x=17.362$
Thus,
Price of movie ticket in Japan is x=7.362$
Price of movie ticket in Switzerland is y=13.652$
Answer:
The fraction of frame did Monica paint blue is 
Step-by-step explanation:
Given as :
The area of square frame = A = 24 square inches
Monica paint 
of one side of the frame blue
Let the measure of one side of frame = x
So, <u>From Area of square</u>
Area = side × side
Or, A = x × x
Or, x ² = 24
∴ x = 
= 2
So, Measure of each side = x = 2
Now, As Monica paint of one side of the frame blue
So, The painted part = × 2
∴ The painted part = 
×
I,e The fraction of painted blue =
Hence, The fraction of frame did Monica paint blue is Answer
