$z-4\frac{2}{3}=2\frac{2}{3}\ \ \ \ |add\ 4\frac{2}{3}\ to\ both\ sides\\\\z=2\frac{2}{3}+4\frac{2}{3}\\\\z=6\frac{4}{3}\\\\\boxed{z=7\frac{1}{3}}$

So z-4 2/3=2 2/3
so 4 2/3=12/3+2/3=14/3
2 2/3=6/3+2/3=8/3
z-14/3=8/3
multiply both sides by 3
3z-14=8
add 14 to both sides
3z=22
divide both sides by 3
z=22/3=7 1/3

An amusement park sells child and adult tickets at a ratio of 3:1. On Saturday, they sold 63 adult tickets. How many child ticke

nalin [4]

Answer:

The number of child tickets sold by the amusement park is 189.

Step-by-step explanation:

Let A represent the number of adult tickets and C represents the number of child tickets, therefore we have:

3:1 = C:A .................... (1)

Where;

C = ?

A = 63

Substituting for the value into equation (1), we have:

3:1 = C:63

This can be converted to solve for C as follows:

3 / (3 + 1) = C / (C + 63)

3 / 4 = C / (C + 63)

0.75 = C / (C + 63)

0.75(C + 63) = C

0.75C + (0.75 * 63) = C

0.75C + 47.25 = C

47.25 = C - 0.75C

47.25 = 0.25C

C = 47.25 / 0.25

C = 189

Therefore, the number of child tickets sold by the amusement park is 189.

George had one sheet of paper. He cut it into 6" x 5", and 3" x 6". What were the dimensions and total area of his original shee

Deffense [45]

Answer: $l={8}'' ,b={6}''$ , $l={6}'' ,b={8}''$

and area is $=48$ inch square

Step-by-step explanation:

area of sheet $=l\times b$

area of sheet first $={6}''\times {5}''$

$=30$ inch square

area of sheet second $={3}''\times {6}''$

$=18$ inch square

total area of both sheet $=30+18$

$=48$ inch square

area of sheet $=l\times b$

$=48$ inch square

$l={6}'' ,b={8}''$

$l={8}'' ,b={6}''$

perimeter of sheet

$=2\left ( l+b \right )$

$=2(6+8)$

$={28}''$

What is the answer to this?

nekit [7.7K]

Answer:

Step-by-step explanation:

Y= 1x^2 + 3x + 9

Y= Ax^2 + Bx + C

To determine which way a parabola opens just look at the coefficient (the number) of the x^2 - Always use the coefficient that is beside the x^2

So, if the coefficient A is positive the parabola is opening upward

if the coefficient A is negative the parabola is opening downward
