Use the following word problem for questions 7 and 8 below. A total of 564 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold? 7) Which equation below could be used to find the number of adult tickets that were sold. *

7 + 8x = 564
7x + 8x = 564
A + 3A = 564
A + 3 = 564
3A = 564

A+3A=564

Step-by-step explanation:

As A is the no. of Adult tickets solds are denoted as 'A' and since the no. of Student tickets sold are 3 times of the adult tickets sold meaning 3 times A, denoted as 3A, when we sum them up, it equates to the total no. of tickets sold

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
