write a system of equations to describe the situation below, solve using elimination, and fill in
the blanks.
dr. larson, a pediatrician, has 3 annual checkups and 1 sick visit scheduled next tuesday,
which will fill a total of 198 minutes on his schedule. next wednesday, he has 2 annual
checkups and 1 sick visit on the schedule, which should take 138 minutes. how much time is
allotted for each type of appointment?
minutes for an annual checkup and
minutes for a sick

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
