Answer:
Step-by-step explanation:
7 ) -3p=-48
p=-48/-3
<h2>p=16</h2>
8) -98=7t
t=-98/7
<h2>t=-14</h2>
9) -4.4 y =-4
y=-4/-4.4
<h2>y=1.1</h2>
10) 2.8 c=4.2
c=4.2/2.8
<h2>c= 1.5</h2>
First you multiply
so you will get 6n+6= 18n+29
Then move all "n" on one side of the equation
-23=12n
then divide by 12
the answer should be
n= -1.916
Let a be the number of adults which bought a ticket and c the number of children who bought a ticket. We can use the information given to assemble a system of equations.
Tickets cost 8 dollars for a, 1 dollar for c, and the total amount made is 100
8a + c = 100
The total of a and c is 30
a + c = 30
We can now subtract one equation from the other to use the elimination method to solve the system.
8a + c = 100
-(a + c = 30)
7a + 0 = 70
We can now solve for a.
7a = 70
a = 10
There were 10 adults who bought tickets. We can use this value as a known, plugging it into an equation to solve for the number of children.
a + c = 30
10 + c = 30
c = 20
So, the final answer is "20 children and 10 adults Equation 1: a + c = 30 Equation 2: 8a + c = 100".
We conclude that the solution to the given linear equation is x = 15/13.

How to solve that equation for x?</h3>
Here we have the linear equation:
13x - 4 = 11
And we want to solve this for x. To do so, we need to isolate x in one side of the equation.
We can start by adding 4 in both sides, so we get:
13x - 4 + 4 = 11 + 4
13x = 15
Now we can divide both sides by 13, so we get:
13x/3 = 15/13
x = 15/13
We conclude that the solution to the given linear equation is x = 15/13.
