$(4y - 4) + 3y = 52$

$4y - 4 + 3y = 52$

Collect like terms

$7y - 4 = 52$

Add sides 4

$7y - 4 + 4 = 52 + 4$

$7y = 56$

Divide sides by 7

$\frac{7y}{7} = \frac{56}{7} \\$

$y = 8$

Thus ;

$Angle \: \: W = 4y - 4$

$Angle \: \: W =4(8) - 4$

$Angle \: \: W = 32 - 4$

$Angle \: \: W =28 °$

_________________________________

$Angle \: \: X = 3y$

$Angle \: \: X = 3(8)$

$Angle \: \: X = 24°$

At the city Museum child admission is $5.30 and adult admission is $9.30 on Sunday 146 tickets were sold for a total sales of $1

DerKrebs [107]

Answer:

The number of child tickets is 53

And adult tickets sold out is 93

Step-by-step explanation:

Let the child tickets be x

And the adult tickets be y

x+y = 146 - - - - - - - 1

x= 146-y

5.3x + 9.3y= 1145.80 - - - - - 2

We can substitute x= 146-y in equation 2

5.3(146-y) + 9.3y= 1145.80 - -- 2

773.8 - 5.3y +9.3y = 1145.80

773.8+4y= 1145.80

4y= 1145.80-773.8

4y= 372

y= 372/4

y= 93

We can now substitute y= 93 in equation 1 to find x

x+ 93= 146

x= 146-93

x= 53

Hence

The number of child tickets is 53

And adult tickets sold out is 93

According to u.s. postal regulations, the girth plus the length of a parcel sent by mail may not exceed 108 inches, where by "gi

Pepsi [2]

Let x represent the side length of the square end, and let d represent the dimension that is the sum of length and girth. Then the volume V is given by
V = x²(d -4x)
Volume will be maximized when the derivative of V is zero.
dV/dx = 0 = -12x² +2dx
0 = -2x(6x -d)
This has solutions
x = 0, x = d/6

a) The largest possible volume is
(d/6)²(d -4d/6) = 2(d/6)³
= 2(108 in/6)³ = 11,664 in³

b) The dimensions of the package with largest volume are
d/6 = 18 inches square by
d -4d/6 = d/3 = 36 inches long

The world population in 2013 was about 7.125 billion. In 2003, it was about 6.357 billion. Which number represents the increase

Makovka662 [10]

Answer:

D.

7.68 × 108

Step-by-step explanation:

World population in 2013 was about 7.125 billion

In 2003 , it was about 6.357 billion

Increase = 2013 population- 2003 population

That’s 7.125 billion - 6.357 billion = 0.768 billion

A billion has 9 zeros. When you move The point one place to the right , it reduces the number of zeros by one. you now have

7.68 x 10^8
