The system of equations are solved and the cost of adult ticket and child tickets are $ 6 and $ 4 respectively
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the adult tickets be a
Let the child tickets be c
Group A buys 3 adult tickets and 2 child tickets and pays a total of $26
So , 3a + 2c = 26 be equation (1)
And , Group B buys 5 adult tickets and 3 child tickets and pays $42
So , 5a + 3c = 42 be equation (2)
On simplifying , we get
Multiply equation (1) by 5 and equation (2) by 3 , we get
15a + 10c = 130 be equation (3)
15a + 9c = 126 be equation (4)
Subtracting equation (4) from equation (3) , we get
c = $ 4
Therefore , the cost of child ticket is $ 4
Substituting the value of c in equation (1) , we get
3a + 2 ( 4 ) = 26
3a + 8 = 26
Subtracting 8 on both sides , we get
3a = 18
Divide by 3 on both sides , we get
a = $ 6
Therefore , the cost of adult ticket is $ 6
Hence , the system of equations are solved

this is due in 4 hours plus i have 5 classes left please help
Answer:
Onaje is correct.
Step-by-step explanation:
To start, total up how many shirts we have, and multiply them by t. Since they are the same price, we now have a total for how many shirts they bought. This proves the second and third equations that they wrote. If you take the easy way and just add them, you'll still have 25t, making Onaje's expression correct.
EDIT: Just saw you need why it's incorrect for Paula, just hold on.
So for Paula, it's simple why she is incorrect. If you look at the third equation she wrote, she's adding 25 to 2t, which is completely incorrect, and will come up with a different result than 16t + 9t.
Hope this helps.

Which measure is of an angle that is coterminal with a 95° angle?
Answer:
95° - (1,080 n) °, for any integer n
Step-by-step explanation:
Co-terminal angle are those angles who share the same initial side and terminal sides,
And, these angles are obtained by adding or subtracting the multiple of 360°,
That is, if Ф is an angle,
Then its co-terminal angles are,
Ф + 360 n
Where, n is any integer (negative or positive)
Here, Ф = 95°,
Since, n is an integer,
⇒ - 3n is an integer,
Thus, the co-terminal angles of 95° are,
95° + 360° (-3n)
= 95° - (1080 n) °; for any integer n.
Step-by-step explanation:
Hope this helps!~

Which equation shows how to rewrite the sum of 30 and 45 using their greatest common factor? 30 + 45 = 5(6 + 9) 30 + 45 = 15(2 + 3) 30 + 45 = 5(6) + 15(3) 30 + 45 = 5(6)(3)
Answer: 30 + 45 = 15(2 + 3)
Step-by-step explanation:
The greatest common factor for 30 and 45 will be gotten as follows:
Factor of 30 = 2 × 3 × 5
Factor of 45 = 3 × 3 × 5.
GCF = 3× 5 = 15
Therefore, the equation that shows how to rewrite the sum of 30 and 45 using their greatest common factor will be:
30 + 45 = 15(2 + 3)

By decomposing the design into two rectangular prisms, the surface area of the design is calculated as: A. 256 in.²
What is the Surface Area of a Rectangular Prism?The surface area of a rectangular prism is expressed as, S = 2(lw + lh + wh).
The design can be decomposed into top rectangular prism and bottom rectangular prism.
The surface area of the design = surface area of the top rectangular prism + surface area of the bottom rectangular prism - 2(area of the top rectangular prism that joins the bottom rectangular prism)
Surface area of the top rectangular prism = 2(lw + lh + wh) = 2(5×4 + 5×4 + 4×4) = 112 in.²
Surface area of the bottom rectangular prism = 2(lw + lh + wh) = 2(8×5 + 8×4 + 5×4) = 184 in.²
Area of the top rectangular prism that joins the bottom rectangular prism = l × w = 5 × 4 = 20 in.²
The surface area of the design = 112 + 184 - 2(20) = 256 in.²

Answer:
x = 119, y = 55
Answer:
x = 119°
y = 55°
Step-by-step explanation:
y + 125 = 180 {linear pair}
y = 180 - 125
y = 55°
Sum of all the angles of quadrilateral = 360
x + 55 + 72 +114 = 360
x + 241 = 360
x = 360 - 241
x = 119°
