Answer:
y = 5
Step-by-step explanation:
WY is the perpendicular bisector of XZ and so divides ΔWXZ into 2 congruent triangles ΔWXY and ΔWZY
Hence WZ = WX ← corresponding sides, thus
5y - 8 = 2y + 7 ( subtract 2y from both sides )
3y - 8 = 7 ( add 8 to both sides )
3y = 15 ( divide both sides by 3 )
y = 5
Answer:
14 boys
Step-by-step explanation:
Hi
<span>5(4c-2d) + 2d - 6(d-3c) = 20c - 10d + 2d - 6d + 18c
5(4c-2d) = 5(4c)+5(-2d) = 20c-10d
- 6(d-3c) = -6(d)-6(-3c) = -6d+18c
</span>20c - 10d + 2d - 6d + 18c = 20c + 18c - 10d - 6d + 2d = 38c - 14d
20c+18c = 38c
-10d-6d+2d = -16d+2d = -14d
Answer: 38c-14d

Answer:
26.9
Step-by-step explanation:
Right now we have '8' in the tenths place. That '6' following the '8' requires us to round up. Thus, 26.86 to the nearest tenth is 26.9.
