Answer:

Step-by-step explanation:

WX = XY because (VW = VY)

WX = u + 42

XY = 3u

u + 42 = 3u

42 = 3u - u

42 = 2u

u = 42 / 2

u = 21

Answer:

u = 21

Step-by-step explanation:

Consider triangle XWV and triange XYV

XV = XV (common)

Angle XVW = Angle XVY (given)

VW = VY (given)

∴triangle XWV ≅ triange XYV (SAS)

∴ XW = XY (corr. sides, ≅ triangles)

u + 42 = 3u

u = 21

If Haley's ant farm doubles in population, she will have 122 more ants in her farm than Nate does. Haley's ant farm currently ha

xxMikexx [17]

Answer:

238

Step-by-step explanation:

Start with Raven's ants since hers is the one that everyone else's is based off of.

Raven = 208

Haley has half of that plus 76, so

Haley = (208/2) + 76

Haley = 180

If Haley's farm doubles in population, she would have 360 ants. That number is equal to Nate's number + 122. We have an equation of sorts there to solve for Nate's ants:

180(2) = N + 122 so

360 = N + 122 and

N = 238

Nate has 238 ants in his farm.
