“The captain of a rafting boat takes his crew down river for 6 hours, covering a total of 56 miles. When he realizes he left one of his passengers behind, he is forced to paddle back upriver for 8 miles. The trip back
up took him 3 hours."
A student used the following system of equations to model the situation given above. Which of the
statements is true about the system of equations the student used?
b = the speed of the boat
r = the speed of the current
[8(6-1)=3
1618+r) = 56

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..

true

step-by-step explanation:

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
