2 x 3 x 5 x d x d x d x d x d = 30d5
y - d = cx so d = - cx + y That is the slope-intercept form in the c-d plane. Slope = -x Intercept = y
Circumference Equals Diameter times Pi C = D x π D = 5 C = 5 x π C = 5π² or 15.7ft²
D = {x [element of reals]}R = {y [element of reals]|y >= 4}
d=3c
Speed = Distance divided by Time (S = D/T)Time = Distance divided by Speed (T = D/S)Distance = Speed times Time (D = S x T)
d = 9
bx+cy=d bx=d-cy x=d-cy ----- b answer: d-cy ----- b
S= speed D= distance T= time S= D/T D= S x T T= D/S
The product of the means equals the product of the extremes. In other words, if A is to B as C is to D, then B times C equals A times D, so... A = B x C ÷ D B = A x D ÷ C C = A x D ÷ B D = B x C ÷ A
x = (d-a)/(a-c)

1+x=dd+x so dd=1 so d=1 1+x=89b+x so 89b=1 so b=1/89 bc+x=1+x so bc=1 so c=1/(1/89) = 89 so cd=89 (and x=88)
If a is to b as c is to d, a x d = b x c. The product of the means (b & c) equals the product of the extremes (a & d).
