What is 7 / 2 divided by 4 / 21

Hi, answer 147 / 8

The first n terms of the arithmetic sequence {an}, {BN} and Sn, TN satisfy Sn / TN = 3N + 1 / 2n + 5, then A5 / B5=___ ,a3/b3=___

S9 / T9 = (27 + 1) / (18 + 5) [(a1 + A9) * 9 / 2] / [(B1 + B9) * 9 / 2] = 28 / 23 (a1 + A9) / (B1 + B9) = 28 / 232a5 / 2B5 = 28 / 23a5 / B5 = 28 / 23s5 / T5 = 16 / 15 [(a1 + A5) * 5 / 2] / [(B1 + B5) * 5 / 2] = 16 / 15 (a1 + A5) / (B1 + B5) = 16 / 15

Univariate quadratic equation 100 + 100 (1 + x) + 100 (1 + x) square = 121 [square on 1 + x]

Left factorization
The results are as follows
100( 1+ (1+x) +(1+x)^2 ) =121
Root left and right at the same time
10 radical (x ^ 2 + 3x + 3) = 11
The solution is as follows
X = (- 3 + (radical 46) / 5) / 2
Or x = (- 3 - (radical 46) / 5) / 2

9 * 3 / 8 is equal to?

9×3/8
=27/8

Given that the image of the first-order function y = (m-2) x + m 2-6 intersects with y, the ordinate of the intersection is - 2, the value of M is obtained
As the title

Because: y = (m-2) x + M2-6 over (0, - 2)
So: substituting - 2 = (m-2) 0 + 2m-6
It is found that: - 2 = 2m-6
m=2

200*19.9-199*19.8
The calculation should be simple
200 × 19.9-199 × 19.8 = 200 × 19.9-19.9 × 198 = 19.9 × 2 = 39.8, too much trouble, the teacher said.

The question is very simple!
200*19.9-199*19.8=200*19.9-19.9*198=19.9*2=39.8
