Answer:
x=9
Step-by-step explanation:
I took one side, and made proportions:
12:16
3:4
so, x-1:6=3:4
(x-1)/6=3/4
solve it for x=9
Answer:
There were 58 students in each bus.
Step-by-step explanation:
Total number of students x=
237
Number of students who travelled by car =
5
∴ Number of students who travelled by bus =
237
−
5
=
232
Presuming the buses to have the same capacity, and knowing that there were four buses, the number of students in each bus can be expressed as:
x
=232
÷4
x
=
58

As the six-sided die does not have a side labelled "7", the probability of rolling a 7 is zero.

Ed : (0,205)(4,197)
slope(m) = (197 - 205) / (4 - 0) = -8/4 = -2
y = mx + b
slope(m) = -2
(0,205)...x = 0 and y = 205
time to sub
205 = -2(0) + b
205 = b
equation is : y = -2x + 205...so Ed loses 2 lbs per week
Eric :
y = -1.5x + 200...so Eric loses 1.5 lbs per week
when they started, Ed weighed 205 lbs and Eric weighed 200 lbs
* of the two, Eric loses fewer lbs per week. When the two began their respective weight-loss programs, Ed was heavier by 5 lbs.
