Answer:

y = x - 2.25

230·x + 180·y = 2260

230·x + 180·(x - 2.25) = 2260 --> x = $6.50

An adult ticket costs $6.50.

y = 6.5 - 2.25 = $4.25

Step-by-step explanation:

\text{We know:}\\\\\sin(-\alpha)=-\sin\alpha\\\\\sin(\alpha\pm k\cdot360^o)=\sin\alpha\\\\===============================\\\\\sin(360^o-\theta)=\sin\bigg(-(\theta-360^o)\bigg)=-\sin(\theta-360^o)=-\sin\theta

Answer:

y = 12

Step-by-step explanation:

∵ m∠ABC = 40

∵ BD ray is the bisector of ∠ABC

∴ m∠ABD = m∠CBD = 20

In 2 Δ BAD and BCD:

∵ m∠BAD = m∠BCD = 90°

∵ m∠ABD = m∠CBD = 20°

∵ BD is a common side in the two triangles

∴ ΔABD congruent to ΔCBD⇒(AAS)

∴ AD = CD

∴ 3y + 6 = 5y - 18

∴ 5y - 3y = 6 + 18

∴ 2y = 24

∴ y = 24/2 = 12

We are interested in the dimensions of a certain square. A rectangle has a length of 5 units more than the side of the square an
JulijaS [17]
Lets consider the side of square be 'x' units
So as per data,
Length of rectangle is x+5
Breadth of rectangle is x/2

and also as per data, the areas of rectangle and square are equal.
Area of rectangle = Length * Breadth = (x+5)*x/2 = ( x^{2} +5x)/2 <- equation1
Area of square = Side* Side= x*x = x^{2}  <- equation2

As per given data, Equation1 and equation 2 are equal
so 
( x^{2} +5x)/2 = tex] x^{2} [/tex]  
x^{2} +5x = 2 x^{2}
2 x^{2} -  x^{2}   = 5x
x^{2}  = 5x
x = 5

So the side of square = 5 units  

For Square, both dimensions are equal.

Apply the distributive property to expand the expression.<br> 9(2+5m)
zheka24 [161]
The answer would be (18+45m) because you have to multiply the 9 to the 2 which equals 18 and then do the same for the 5m and which would be 45 because you add the variable at the end
