Solve the given equation.<br><br><br><br> s - 19 = 12
Viktor [21]

Answer:

s=31

Step-by-step explanation:

hi again so what you are gonna do is find out the opposite of subtraction which is addition then you are gonna do the opposite..so add 19 and 12 together then your sum would be 31.....to check your answer you must subtract 31 from 19 and then you get 12....so therefore s=31

hope you are getting a better understanding!

(In picture) “Explain how you know you know using proportional lengths”
gregori [183]

9514 1404 393

Answer:

  yes

Step-by-step explanation:

If GH║FE, then ∆DEF ~ ∆DHG.

In similar triangles, corresponding sides have the same ratios.

The ratios of corresponding sides are ...

  DG/DF = DH/DE

  DG/(DG + GF) = 18/(18+36)

  (1/2GF)/((1/2GF +GF) = 1/3

  (1/2)/(3/2) = 1/3

  1/3 = 1/3

Corresponding sides are proportional. Angle D is congruent to itself, so ∆DEF ~ ∆DHG by the SAS similarity postulate. Angles DGH and DFE are therefore congruent and GH║FE.
