7.20+24.75=31.95
so 31.95 per student
31.95*350=11,182.50
This will cost the student body $11,182.50
Answer:
X=SMALL BOX.
Y=LARGE BOX
THEREFORE,X+Y=21
X=21-Y
THEREFORE,25(21-Y)+70Y=1110 POUNDS
525-25Y+70Y=1110
525+45Y=1110
45Y=1110-525
45Y=585
Y=585/45
Y=13 .
Therefore,13 large box and8 small box..
You would divide 717 by 8 which would result in x equaling 89.7
Answer:
n stands for the unknown number
Step-by-step explanation:
It's the only variable in the equations, so it is the only one that can stand for any unknown.
Okay so let’s start with number one you have 2 out of the 3 sides and you have to solve for the third
Let’s call the side you are looking for side A than the side with 13 side B and the side with 29 side C
So
B=13
C=29
A= ?
You would use the equation
A^2 + B^2 = C^2
So
A^2 + (13)^2 = (29)^2
13^2 = 169
29^2 = 841
So
A^2 + 169 = 841
A^2 = 672
A= 4 times the square root of 42
Or if yu need a estimated answer
A= 25.9
