Girardo is using the model below to solve the equation 3 x + 1 = 4 x + (negative 4). 3 long green tiles and 1 green square tile = 4 long green tiles and 4 red square tiles

Girardo uses the following steps:

Step 1 Add 4 negative x-tiles to both sides
Step 2 Add 1 negative unit tile to both sides
Step 3 The solution is Negative x = negative 5

Which step could be adjusted so that Gerardo's final step results in a positive x-value?
In step 1, he should have added 4 positive x-tiles to both sides.
In step 1, he should have added 3 negative x-tiles to both sides.
In step 2, he should have added 4 negative unit tiles to both sides.
In step 2, he should have added 1 positive unit tile to both sides.

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent

its c or d   take a lucky guess my dude

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
