Answer:
1. x = -5 + 5y
2. x = -5 - y/2
Step-by-step explanation:
Answer:
h = 6 units
Step-by-step explanation:
The formula for the volume of a tetrahedron is given as :
V = sh
Where
s is area of base and h is height
Put s = 8 and V = 48 to find h as follows :

So, the height of the tetrahedron is 6 units.
Answer:
36
Step-by-step explanation:
X equals 12, substitute X for 12
3(12)=36
One number is 4 times the other, so x and 4x.
The sum of two numbers is 4x+x=70.
Solve for x to get
x=70/5=14
the other number is 4x=4*14=56
Answer:
636
Step-by-step explanation:
5xyz+3y
5(2.5)(12)(4)+3(12)
(12.5)(48)+36
600+36
636
