Answer:
2.34
Step-by-step explanation:
Divide the total by the number of bags!
28.08/12=2.34
CHECK: 2.34*12=28.08

Answer:
The inequality in this case is 100 + 400*t > 500 + 350*t and for B to be cheaper Sophia has to rent it for more than 8 months.
Step-by-step explanation:
In order to write the inequality we first need to write two equations one for each apartment. For apartment A we have a fixed cost of $100 and a variable cost of $400 that varies according to the time living in there, so we have:
rent = 100 + 400*t
For apartment B we have a fixed cost of $500 and a variable cost of $350 that varies according to the time living in there, so we have:
rent = 500 + 350*t
In order for the total paid in B to be less than for the one in A we need to satisfy the following inequality:
100 + 400*t > 500 + 350*t
400*t - 350*t > 500 - 100
50*t > 400
t > 400/50
t > 8 months
The inequality in this case is 100 + 400*t > 500 + 350*t and for B to be cheaper Sophia has to rent it for more than 8 months.
Answer:
6. 135°
7. 135°
Step-by-step explanation:
You have to assume that the figure is a regular octagon, so has central angles equal to exterior angles equal to 45°.
6. A regular anything is circumscribed by a circle, so the measure of any inscribed angle is half the measure of the corresponding central angle. That is, ∠BET =∠TBA = (45°)/2, so their sum is 45°. ∠BOT is the supplement of that, 180° - 45° = 135°.
__
7. ∠GIT + ∠ITS is the same measure as one internal angle of the octagon. That is the supplement of the exterior angle we identified above as being 45°.
∠GIT + ∠ITS = 135°
Denominators of fractions cannot be zero, therefore the domain is all real numbers besides 2, for that is the only number that will falsify the fraction
If they all have the same variable it will be much easier to solve cause they’re all like terms. so you just take 10-5 which is 5 plus 3 which is 8 and 8 minus 8 is 0.
