shtirl [24]3 years ago
8 0

Answer:

Zachary is 9, Nicole is 8, and Jaycob is 27.

Step-by-step explanation:

x=Zachary

y=Nicole

z=Jaycob

x+y+z=44

x*3=z

x-1=y

However, for now, let's just assume that  x and y are actually the same, and that the answer is actually 45.

so, x*3=z, and y*3 also equals z.

This is so that technically, 45/5=x, because z accounts for 3, and both x and y account for 1 each, meaning altogether it should be 5 you should be dividing by. 45/5=9, so x=9. Now that we have that figured out, we can solve the rest easily. 9-1=8, so there's your y, and 9*3=27. 27+9=36, and 36+8=44.

Solve.<br><br> 3 = –(–y + 6)
o-na [289]

3=−(−y+6)

Simplify:

3=−(−y+6)

3=y+−6(Distribute)

3=y−6

Flip the equation.

y−6=3

Add 6 to both sides.

y−6+6=3+6

y=9

The perimeter of the square piece of gold is 12 milllimeter. how long is each side
Firdavs [7]
48 mm long

Since a square has all equal sides, it will be 12mm for all sides

Perimeter = L (Length) + W (Width) + L + W
(In this case since it’s a 2D shape)

12 + 12 + 12 + 12 = 48

Hope this helped :)
