Answer:
150 children200 adultsStep-by-step explanation:
The equations can be written as ...
y = 350 -x . . . . . . . . total number of people
4x +2y = 1100 . . . . . admission fees collected
Substituting for y, we have ...
4x +2(350 -x) = 1100
2x = 400 . . . . . . . . . . . . subtract 700, collect terms
x = 200
y = 350 -200 = 150
150 children and 200 adults attended the fair.

A meal that cost $50 had a 20% tip and 5% sales tax. How could you calculate your final total bill?
Answers
Answer:
$57.50
Step-by-step explanation:
find 10% of 50 first, which is 5, because 5 × 10 = 50, then add $10 to the $50 beacause 50 × 0.2 = 10, next, remove 5%, to do this divide 10% by 2 to get $2.50, 60 - 2.5 = 57.5

a large painting has a length of 18 inches and width of 12 inches. If each dimension is reduced by x inches to make the ratio of length to width 5 to 3, what is the value of x
Answers
Answer:
The value of x = 3.
Step-by-step explanation:
The ratio between length and width is given by:
[tex]\frac{L}{W}=\frac{5}{3}[/tex]
Where:
L represents the new length W represents the new widthNow, we know that each dimension is reduced by x inches, it means:
[tex]L=18-x[/tex]
[tex]W=12-x[/tex]
Then, we will have:
[tex]\frac{18-x}{12-x}=\frac{5}{3}[/tex]
Finally, we just need to solve it for x.
[tex]3(18-x)=5(12-x)[/tex]
[tex]5x-3x=60-54[/tex]
[tex]2x=6[/tex]
[tex]x=3[/tex]
Therefore, the value of x = 3.

−5x + y = −3
3x − 8y = 24
Answers
Answer:
x = 0
y = -3
Step-by-step explanation:
-5x + y = -3 --------------(I)
3x - 8y = 24 ------------(II)
Multiply the equation (I) by 8
(I)*8 - 40x + 8y = -24
(II) 3x - 8y = 24 {Add and y will be eliminated}
-37x = 0
x = 0
Plugin x = 0 in equation(I)
-5*0 + y = -3
0 + y = -3
y = -3
Answer:
- 5x + y =-3 ......1
3x -8y = 24.........2
eqn 1 is multiply by 8 .we get -40 x +8y=-24 .....3
-40 x +8 y =-24 ...........3
3 x - 8y = 24 ......... 2
·································
-37 x +0 = 0
··························
x =0
put x = 0 in equation 2
3 x -8 y =24
3×0 -8 y = 24

Answer:
C) the graphs of the function are a reflection across the line, y = x
Step-by-step explanation:
Inverse functions have graphs that are reflections over the line y = x and thus have reversed ordered pairs.

When that two functions are INVERSES of each other then
The graphs of the functions are a reflection across the line y = x
Option C
Given :
The two functions that are inverse to each other
When two functions are inverse to each other then
the domain of function f is the range of inverse function
The range of function f is the domain of inverse function
x values of function f = y values of inverse function
y values of function f = x values of inverse function
Hence we can say that the graph of function are reflection across y=x
The graphs of the functions are a reflection across the line y = x

So to find volume it is length x width x height or base x height
So let’s say
L=9.6
W= 5
H= 7
9.6•5=48
Now the base would be 48
48•7=336
To check if it is right, change the values around.
7•5= 35 and 35•9.6=336
7•9.6= 67.2 and 67.2•5=336
