Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.
Bridgette wants to attend more group exercise classes at her gym. This week, she plans to
attend 4 cardio classes and 5 weightlifting classes, which will last a total of 339 minutes. Next
week, she hopes to attend 3 cardio classes and 1 weightlifting class, which will last a total of
158 minutes. Given that all cardio classes and all weightlifting classes are the same length,
how long is each class?
Every cardio class lasts for
minutes.

1x2x4x7x87

Step-by-step explanation:

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}

i got 142 as my answer
