Can u Simplify this problem???!? 3t-7t+14t

Come on now, Tayala !

What if I say to you:
"Start with 3 cows, take away 7 cows, and then add 14 cows. How many are there ?"

Don't let the little 't' scare you.  It doesn't matter one bit what 't' really is.  It can be
a number, a teacher, a tiger, or a teacup.  Whatever it is, you start with 3 of them,
take away 7 of them, and then add on 14 of them.  How many are there ?

Hint:  If there are not ten of them, then go back and look at the cows again.

ANSWER ASAP (EXTRAS POINTS) 5.3n + 7.75 = 70.85, What is the value of n?
Verizon [17]

Answer:

Around 11.9

Step-by-step explanation:

5.3n + 7.75 = 70.85

First subtract 7.75 on both sides.

5.3n = 63.1

Then divide both sides by 5.3

n=11.9 (I rounded to the nearest tenth.)

System of Equations Problem

Sarah bought 3 first class tickets and 7 coach tickets.

Step-by-step explanation:

Given,

Number of people = 10

Total amount spent on tickets = $4830

Cost of each coach ticket = $270

Cost of each first class ticket = $980

Let,

x be the number of coach tickets

y be the number of first class tickets

According to given statement;

x+y=10      Eqn 1

270x+980y=4830   Eqn 2

Multiplying Eqn 1 by 270

270(x+y=10)\\270x+270y=2700\ \ \ Eqn\ 3\\

Subtracting Eqn 3 from Eqn 2

(270x+980y)-(270x+270y)=4830-2700\\270x+980y-270x-270y=2130\\710y=2130

Dividing both sides by 710

\frac{710y}{710}=\frac{2130}{710}\\y=3

Putting y=3 in Eqn 1

x+3=10\\x=10-3\\x=7

Sarah bought 3 first class tickets and 7 coach tickets.
