Find cost per choc 248/4 = 62 / choc 62 per choc x 11 choc = 682
w = 3 (2a+b)-4 add 4 to both sides
w+4 = 3(2a+b) expand R side
w+4 = 6a + 3b subtract b from both sides
w+4-3b = 6a divide both sides by 6
a = (w+4-3b)/6
P
L = P+2
M = 2P Summed = 26 kg
P + P+2 + 2P = 26
4P = 24
P = 6 L = 8 M = 12
y= 4x+12-5 = 4x + 7 change the x to y and the y to x of the original function then solve for y
y = 4x+7 switch the x 's and y 's
x = 4y+ 7 now solve for y
x-7 = 4y
y = (x-7)/4 this is the inverse
g(x) = ((x-1)/4) put in x=5
g(5) = (5-1)/4 =1
f(x) = x² − 3x + 3 Put in x = 1
1^2 -3(1) + 3 = 1
1 inch = 4 feet
1 inch = 4x12 = 48 inches
scale factor 1:48
.94s = 1.14 v where s and v are the priginal populations
s/v = 1.14/.94
= 114 /94 = 57/47
30 x + 20 (35-x) = 900 solve for 'x' the 30L sprinkler hours then 35-x = 20L hours
(3 + x)/(5 + x) = (1 + x)/(2 + x)
(x+3)(x+2) = (x+1)(x+5)
x^2 + 5x + 6 = x^2 + 6x + 5
1 = x
Surface area = pi x d x h x #columns
= pi x 10 x 18 x 16 = 9047.789ft2
9047.79 ft2 / 350 ft2/gal = 25.85 ~ 26 gallons
