Given :
The admission fee at a small fair is $1.50 for children and $4.00 for adults.
On a certain day, 2,200 people enter the fair and $5,050 is collected.
To Find :
How many children and how many adults attended.
Solution :
Let, number of children and adults attended are c and a.
So, c + a = 2200 ....1)
Now, fair collected is given by :
1.5c + 4a = 5050 ....2)
Putting value of a from equation 1) to 2), we get :
1.5c + 4( 2200 - c ) = 5050
1.5c - 4c = 5050 - 8800
2.5c = 3750
c = 1500
a = 2200 - 1500
a = 700
Therefore, 1500 children and 700 adults attended the fair.

Write down the integer values of x that satisfy the inequality -2 < x _<4
Those integers are {-1,0,1,2,3,4} (integers in the range -2 and 4)
The integer values of x that satisfy the given inequality are {-2, -1, 0, 1, 2, 3, 4}.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is -2<x≤4.
The integer values of x that satisfy the inequality are
{-2, -1, 0, 1, 2, 3, 4}
Therefore, the integer values of x that satisfy the given inequality are {-2, -1, 0, 1, 2, 3, 4}.

Find the value of x.
Answer:
x=6
Step-by-step explanation:
24=4x
divide both by 4
equals 6
Answer:
to find x we have to find the similarly between the smaller and the larger triangle
the two triangle are similar by side angle side(SAS) similarly therom.
we have to see carefully that the two triangle are similar but not congruent.
Step-by-step explanation:
so the bigger triangle is twice big as the smaller.

[tex]x_1=5,\\x_2=2[/tex]
Step-by-step explanation:
Problem 1:
The angles [tex]\angle 3[/tex] and [tex]\angle 7[/tex] are corresponding, and thus are equal to each other. We can then set up the following equation:
[tex]5x+2=27,\\5x=25,\\x=\fbox{$5$}[/tex].
Problem 2:
The angles [tex]\angle 6[/tex] and [tex]\angle 4[/tex] are supplementary, meaning they add up to [tex]180^{\circ}[/tex]. Therefore, we have the following equation:

Help pls!! Find the value of x and m
Answer:
The answer's the third one listed.
Step-by-step explanation:
The equation to solve for x is:
6x + 16 + 10x - 6 + 90 = 180
16x + 100 = 180
16x = 80
x = 5
To solve for angle BCD, just substitute 5 for x

m = 50 - 6
m = 44

Solve the system of linear equations by elimination.
-3.x – 5y = -7
-4x + 5y = 14
Answer:
(- 1, 2 )
Step-by-step explanation:
Given the 2 equations
- 3x - 5y = - 7 → (1)
- 4x + 5y = 14 → (2)
Add the 2 equations term by term to eliminate y , that is
- 7x + 0 = 7
- 7x = 7 ( divide both sides by - 7 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (1)
- 3(- 1) - 5y = - 7
3 - 5y = - 7 ( subtract 3 from both sides )
- 5y = - 10 ( divide both sides by - 5 )
y = 2
solution is (- 1, 2 )
Answer:
( -1, 2)
Step-by-step explanation:
Since this is asking for elimination, you will need to line up x or y to be the opposite amount:
-3x -5y = -7
-4x + 5y = 14
(notice -5y and 5y are already opposite, therefore no further actions are needed to line them up.)
Next step is to add both equations up to eliminate y and to find x:
-7x = 7
x = -1
After finding x, plug the x back into either one of the equations to solve for y. If you are unsure, you can plug it into the other equations to double check.
If you chose to do equation 1:
-3(-1) -5y = -7
3 -5y = -7
-5y = -10
y = 2
If you chose to do equation 2:
-4(-1) + 5y = 14
4 + 5y = 14
5y = 10
y = 2
After finding x and y, you will find the point ( -1, 2)
1. What is the slope of a line that is perpendicular to the x-axis
Answer:
The slope of a line that is perpendicular to the x-axis is undefined.
Step-by-step explanation:
We know that the x-axis is a horizontal line.
We also know a line that is perpendicular to the x-axis is basically a vertical line.As the slope of a perpendicular line is undefined because no matter what the value of y is, the x-value remains the same.Therefore, the slope of a line that is perpendicular to the x-axis is undefined.
For example, the slope between (1, 2) and (1, 4) is:
Using the slope formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [4 - 2] / [1 - 1]
= 2 / 0

Flying against the wind , an airplane travels 3660 kilometers in 6 hours. flying with the wind , the same plane travels 3800 kilometers in 4 hours. what is the rate of the plane in still air and what is the rate of the wind?
Answer:
...
against the wind, an airplane travels 3640 km in 7 hours.
with the wind, the same plane travels 6000 km in 6hrs.
...
let speed of plane in still air be x mph
speed of wind be y mph.
..
t=d/r
..
against wind speed = x-y mph
with wond speed = x=y mph
...
3640/(x-y)=7
3640 = 7x-7y
/7
520=x-y.....................1
...
6000/x+y = 6
6000 = 6x+6y
/6
1000=x+y.....................2
...
Add (1) & (2)
2x=1520
/2
x=760 mph speed of plane in still air
...
plug value of x in 2
1000=760+y
100-760=y
240 = y
240 mph speed of wind

Hey there!
According to the question, you need to find out the distance from your friend's house to school.
Firstly figure out the coordinate of your school and school. Then use formula of distance.
So, we find the coordinates as (7,7) and (5,0).
So, x 1 = 7 y1= 7
x 2 = 5 y2 = 0
~ Use distance formula.
[tex]d = \sqrt{( {x2 - x1)}^{2} + ( {y2 - y1)}^{2} } [/tex]
~ Put all values.
[tex]d = \sqrt{ {(5 - 7)}^{2} + ( {0 - 7)}^{2} } [/tex]
~ Simplify it.
[tex]d = \sqrt{ {( - 2)}^{2} + {( - 7)}^{2} } [/tex]
[tex]d = \sqrt{4 + 49} [/tex]
[tex]d = \sqrt{53} [/tex]
D= 7.280
Therefore, the distance between your friend's house and your school is 7.3 units.
Hope it helps....
