Answer is C
Plug in the given number for each equation.

35/5=7, this does not match answer choice
55(35)= 1925, this does not match answer choice
105/35=3, this matches answer choice
15+35=50, this does not match answer choice

I do not understand what subscript numbers mean

alekssr [168]

Answer:

subscripts identify different instances of objects that have a similar meaning or definition

Step-by-step explanation:

You apparently are interested in the meaning of the subscript N in the explicit formula ...

$A_N=\dfrac{7N}{N+5}$

Here, it is used to identify different terms of a sequence. When a value is substituted for N, it replaces all instances of N. Using your example, the first three values of $A_N$ are ...

$\text{for N=1: }A_1=\dfrac{7\cdot 1}{1+5}=\dfrac{7}{6}\\\\\text{for N=2: }A_2=\dfrac{7\cdot 2}{2+5}=\dfrac{14}{7}=2\\\\\text{for N=3: }A_3=\dfrac{7\cdot 3}{3+5}=\dfrac{21}{8}$

So, if you're asked to find the 20th term of the sequence, you put 20 where N is, then do the arithmetic.

Subscripts are also used to identify elements of a matrix or coordinates in multiple dimensions. For this purpose, there may be 2 (or more) subscripts, whose order has meaning. The subscripts 24, for example, in $A_{24}$ refer to row 2, column 4 of a matrix named A. That is, the subscripts are in row, column order.

In short, subscripts are used to identify different instances of similar objects.

A and B together complete a work in 20days. They worked together for 5days and B leaves. How long will A takes to finish the rem

andreev551 [17]

Answer:

27 days

Step-by-step explanation:

A alone, rate per day = 1/36

A and B together, rate per day = 1 / 20

Total Workdone for 5 days :

1/ 20 * 5 = 5 / 20 = 1/4

Fraction of work left :

1 - 1/4 = 3/4

3 / 4 * 36 /1

= (3 * 36) / 4

= 108 / 4

= 27 days

9-2x=19

or,-2x=19-9

or,-2x=10

or,x=10/-2

therefore,
