The population of the Boom town increased by 25% compared to last year, present population is 6000 then last year population is equal to 4800.
As given in the question,
Given population of the present year is equal to 6000
Let us consider 'x' be the last year population.
Increased in population compared to last year = 25%
Required equation is given by :
x + (25/100)x = 6000
⇒ (125 / 100 )x = 6000
⇒ x = ( 6000 × 100 ) / 125
⇒ x = 4800
Therefore, the population of the last year as per given data of the present year is equal to 4800.
The above question is incomplete, the complete question is:
Compared to last year, the population of Boom Town has increased by 25%. The population is now 6,000. What was the population last year?

Simon's photo album has 8 photos of his car and some photos of his motorbike
He replaced some of the photos of his motorbike with some more photos of his car.
The number of photos of his car became 12. The ratio of the number of photos of his car to his motorbike became 3:5. How many photos of Simon's bike was there in the album ORGINALLY?
There were 24 photos of Simon's motorbike in the album originally.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
Let x be the number of photos of Simon's motorbike in the album originally.
We know that the number of photos of his car became 12, so the number of photos of his car originally was 8.
We also know that the ratio of the number of photos of his car to his motorbike became 3:5.
So the number of photos of his car and his motorbike originally was x-4.
We can set up the following equation:
12/(x-4) = 3:5
We can cross-multiply and simplify to get:
3x - 12 = 60
3x = 60 + 12
3x = 72
x = 72/3
x = 24
Hence, originally there were 24 photos.

Why is it called substitution method?
It is called the substitution method because we substitute the value of one variable with another one and solve the equation.
By changing the value of another variable in an equation, the variable can be eliminated using this method. Thus, the elimination by substitution method is the name given to this technique.
As we are aware, the substitution approach entails solving the equation to determine the value of the variable, which is then substituted in the other equation. The elimination approach, in contrast, involves removing variables from the equation such that the equation's system can be reduced to being the function of a single variable.

Answer:
no although they were close
Step-by-step explanation:
One Kung Pao chicken and two Big Macs provide 2620 calories. Two Kung Pao chickens and one Big Mac provide 3740 calories. Find the caloric content of each item.
One Kung Pao chicken contains 1620 calories. One Big Mac contains 500 calories.
What is an equation?
A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.
Assume that one Kung Pao chicken content x calories and one Big Mac content y calories.
Given that one Kung Pao chicken and two Big Macs provide 2620 calories.
Two Kung Pao chickens and one Big Mac provide 3740 calories.
Now using the variable finding calories:
One Kung Pao chicken and two Big Macs provide x + 2y calories.
Two Kung Pao chickens and one Big Mac provide 2x + y calories.
The system of equations is:
x + 2y = 2620 ......(i)
2x + y = 3740 .....(ii)
Using the elimination method to solve the given equations.
Multiply equation (i) by 2 and subtract it from equation (ii)
2x + y = 3740
2x + 4y = 5240
(-) (-) (-)
_____________
-3y = -1500
Divide both sides by -3:
y = 500.
Putting y = 500 in equation (i)
x + 2(500) = 2620
x + 1000 = 2620
x = 1620

How many images are formed If two plane mirror are position at an angle of 450?
There are seven images are formed If two plane mirrors are positioned at an angle of 45°.
The formula for the number of images formed by two plane mirrors placed at a certain angle is
⇒360/n
where n=angle between the mirrors
The most important thing to remember is that every time the number of images formed is only ODD numbers, if the result is even then you need to subtract 1 from that.
if it is odd u need not subtract, since the number of images ever formed is only odd.
so for an angle, of 45° the number of images formed are:
⇒360/45=8
in this case, since the images formed are even u need to subtract 1 from it i.e
8–1=7
So, the number of images formed is 7.

A alone can do piece of work in 6 day and B alone in 8 day. A and B undertook to do it for $3200. With the help of C, they completed the work in 3 day. How much i to be paid to C?
If A alone can do a piece of work in 6 days and B alone in 8 days, then A and B undertook to do it for $3200 and complete the work in 3 days with the help of C, then C would be paid 400 dollars.
Therefore the answer is $400.
This is a work and time problem that can be solved using the concept of rate of work. Let's call the amount to be paid to C as "x".
A can do 1 piece of work in 6 days. Therefore, his rate of work is 1/6.
B can do 1 piece of work in 8 days. Therefore, his rate of work is 1/8.
Amount of work A and B can do in 3 days is
= 3×(1/6) + 3×(1/8)
= 3×(1/6)×(4/4) + 3×(1/8)×(3/3)
= 12/24 + 9/24
= 21/24
= 7/8
So amount of work C doing is
= 1 - 7/8
= 1/8
As C do 1/8 amount of work, the amount C would receive is
