Answer:
Step-by-step explanation:
1a+1b(a+b-c)+1b+1c(b=c-a)+ 1a+1c(c+a-b)
1a+1b-c+1b +1c-a+1a+1c-b
1a+2b-c+a+1c-b
2a+1b+c this is the answer I think lol
Answer:
just remove the parentheses and add the numbers
Step-by-step explanation:
Answer:
15 Kg cm²
Step-by-step explanation:
Given that V varies inversely with P then the equation relating them is
V = 
← k is the constant of variation
To find k use the condition
V = 360, P = 20, then
360 = 
( multiply both sides by 20 )
k = 7200
V = 
← equation of variation
When V = 480, then
480 = ( multiply both sides by P )
480P = 7200 ( divide both sides by 480 )
P = 15
Answer:
x = 3
Step-by-step explanation:
-6x - 20 = -2x + 4 (1 - 3x)
Distributive property
-6x - 20 = -2x + 4 - 12x
Combine like terms
-6x - 20 = -14x + 4
Add 14x to both sides
-6x - 20 + 14x = -14x + 4 + 14x
Simplifying
8x - 20 = 4
Add 20 to both sides
8x = 24
Divide both sides by 8
x = 3
