1. To solve for s you need to get s alone on the left side.
2. subtract 4t from both sides of the equation.
s+4t=r
-4t -4t
3. Your answer is:
s=r-4t
<span>Answer:
P=27
Q=10
TC=280
TC=FC+VC
FC=30
VC=280-30=250
TR=Q*P=10*27=270
Profit=TR-TC=270 - 280= -10
In short-tun Bob should continue mow lawns because he covers fixed costs (overvice instead of loss -10 he would had loss amounting fixed costs - 250)
In long-run he should close production.</span>
Geometric progresión:
we can calculate any term, using this rule:
an=a₁*r^(n-1)
a₁=the first term
r=the common ratio
a₆=128
r=2
an=a₁ * r^(n-1)
128=a₁ * 2⁶⁻¹
128=a₁ * 2⁵
128=a₁ * 32
a₁=128/32=4
Solution: a₁=4
You can solve this with a calendar. So you need to count 90 days until the 90th day which is November 22,2016.
1 addition property of equality
Since there the -9 disappeared on the left and the +7 changed by 9 to a +16, 9 must have been added to both sides of the equation, and the addition property of equality states that the equation remains true when the same thing is added to both sides.
