Find the sum of the first 7 terms of the following series, to the nearest integer.

Virty [35]

Answer:

$r = 2.5 \\ sum = \frac{a( {r}^{n - 1} )}{r - 1} \\ = \frac{125( {2.5}^{7 - 1} )}{7 - 1} \\ = \frac{30517.6}{6} \\ = 5086.3$

Is 11/2 and 6/11 equivalent? Plz I need the help☹️

trapecia [35]

For this case we have the following fractions:

$\frac {11} {2}\\\frac {6} {11}$

We must rewrite the fractions, using the same denominator.

We have then:

We multiply the first fraction by 11 in the numerator and denominator:

$\frac {11} {2} \frac {11} {11}$

We multiply the second fraction by 2 in the numerator and denominator:

$\frac {6} {11} \frac {2} {2}$

Rewriting we have:

For the first fraction:

$\frac {121} {22}$

For the second fraction:

$\frac {12} {22}$

We note that:

$\frac {121} {22}> \frac {12} {22}$

Answer:

The fractions are not equivalent:

$\frac {11} {2}> \frac {6} {11}$

Vlada [557]

Answer:

The answer to your question is There were sold 166 adult tickets and 294

children tickets.

Step-by-step explanation:

Data

Total number of seats = 460

cost for adults = a = $52

cost for children = c = $26

Total cost = $16276

Process

1.- Write equations to solve this problem

a + c = 460 Equation l

52a + 26c = 16276 Equation ll

2.- Solve the system of equation by substitution.

-Solve equation l for a

a = 460 - c

-Substitute a in equation ll

52(460 - c) + 26c = 16276

-Expand

23920 - 52c + 26c = 16276

-Simplify

-26c = 16276 - 23920

-26c = -7644

c= -7644/-26

c = 294

3.- Find a

a = 460 - 294

a = 166
