Answer:
x = 5
Step-by-step explanation:
If x + 5 = 10, then x would have to be 5 because 5 + 5 = 10.
The way you would solve this would be:
x + 5 = 10
subtract 5 from both sides of the equation
x + 5 - 5 = 10 - 5
simplify:
x = 5

Quest
Suppose the supply for a certain textbook is given by P
Find the equilibrium quantity and the equilibrium price.
and demand is given by p= - +10, where p is the price and q is the quantity. The graph of these equations is shown to the right.
Answers
Answer:
(d) is correct
Equilibrium quantity is 4.5
Equilibrium price is 5
Step-by-step explanation:
Given
[tex]p = \frac{1}{4}q^2[/tex] -- supply
[tex]p = -\frac{1}{4}q^2 + 10[/tex] -- demand
Required
Find the equilibrium price
Equilibrium price is when:
[tex]Demand = Supply[/tex]
This means that (d) is correct
So, we have:
[tex]p =p[/tex]
[tex]\frac{1}{4}q^2 = -\frac{1}{4}q^2 + 10[/tex]
Collect Like Terms
[tex]\frac{1}{4}q^2 +\frac{1}{4}q^2= + 10[/tex]
[tex]\frac{1}{2}q^2 = 10[/tex]
Multiply both sides by 2
[tex]2*\frac{1}{2}q^2 = 2*10[/tex]
[tex]q^2 = 20[/tex]
Take the square root of both sides
[tex]q = \sqrt{20[/tex]
[tex]q = 4.47[/tex]
[tex]q = 4.5[/tex] -- approximated
The equilibrium price is:
[tex]p = \frac{1}{4}q^2[/tex]
Substitute value for q^2
[tex]p= \frac{1}{4}*20[/tex]
[tex]p = 5[/tex]

8 The cost of a laptop increased by 25% between
2015 and 2019
In 2019. the laptop cost £1000
How much did the laptop cost in 2015?
Answers
Given:
The cost of a laptop increased by 25% between 2015 and 2019.
In 2019, the laptop cost £1000.
To find:
The cost of the laptop in 2015.
Solution:
Let x be the cost of the laptop in 2015.
The cost of a laptop increased by 25% between 2015 and 2019. So, the cost of the laptop in 2019 is
Cost of laptop in 2019 = [tex]x+\dfrac{25}{100}x[/tex]
= [tex]x+0.25x[/tex]
= [tex]1.25x[/tex]
In 2019, the laptop cost £1000.
[tex]1.25x=1000[/tex]
[tex]x=\dfrac{1000}{1.25}[/tex]
[tex]x=800[/tex]
Therefore, the cost of the laptop in 2015 is £800.

One season, the Hornets won 20 games. They played a total of 25 games. Write an equation to find the number of games the Hornets lost.
Answers
Answer:
25 - 20 = 5
Step-by-step explanation:
Since the Hornets have played a total of 25 games and won only 20 of them, you want the difference between the two to figure out how many games the Hornets lost.
t = total games played
w = games won
l = games lost
t - w = l

A sum of money is divided among Khairul, Michael and Ethan in the ratio
6:4: 5. After Khairul gives $30 to Michael and $15 to Ethan, the ratio
becomes 7:6:7. Find the amount of money Khairul had initially.
Answers
Answer:
$360
Step-by-step explanation:
The intial ratio of the sum shared between Khairul, Michael and Ethan is 6 : 4 : 5.
This would be 6x : 4x : 5x
Khairul gives $30 to Michael and $15.
The ratio is. Now;
(6x - 45) : (4x + 30) : (5x + 15)
We are told this is equal to the ratio 7:6:7
Thus;
((6x - 45) + (4x + 30))/(5x + 15) = (7 + 6)/7
(10x - 15)/(5x + 15) = 13/7
Factorize the left hand side;
5(2x - 3)/5(x + 3) = 13/7
5 will cancel out to get;
(2x - 3)/(x + 3) = 13/7
Cross multiply to get;
7(2x - 3) = 13(x + 3)
14x - 21 = 13x + 39
14x - 13x = 39 + 21
x = 60
Amount Khairul had initially was denoted as 6x.
Thus,6x = 5 × 60 = $360
