Answer:
Step-by-step explanation:
Given,
Length of base (a) = 8m
Height of pyramid (h1) = 6m
Height of cuboid (h2) = 10m
Now,
Volume (V) = a²h2 + 1/3 * a²h1
= 64 * 10 + 64 * 6/3
= 640 + 128
= 768 m³
Answer:
T < - 4

Answer:
The answer for 3 is 6 I belive
Step-by-step explanation:
all the rest is easy but you cut 1. off and Im lazy rn
5x - 4y = 42 ------ (1)
x - 6y = 24 ----------(2), multiply eq. 2 by 5 we get
5x - 30y = 120 -----(3),
now use eq. (3) - (1),
5x - 30y = 120
-(5x - 4y = 42)
- 30y + 4y = 120 - 42,
-26y = 78, y = -78/26 = -3,
x = 24 + 6y = 24 + (6*[-3]) = 24 - 18 = 6,
x = 6, y = -3.
