3/7+[-6/11]+[-8/21]+[5/22]​

-125/462

Step-by-step explanation:

This is my answer... hope it really helps you

3/7+(-6/11)+(-8/21)+(5/22)

3/7-6/11-8/21+5/22

now we need to take LCM for 7,11,21,22

so the LCM=462

198-252-176+105/462

303-428/462

-125/462

Step-by-step explanation:

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
