Arlene read 30 pages. That is 10 pages more than half of the pages Taylor read. How many pages did Taylor read?
Write an equation in the form px+q=r to represent this problem.
__x +__ = __
Let's represent the number of pages Taylor read with the variable "x".
Given that Arlene read 30 pages, which is 10 pages more than half of what Taylor read, we can write the equation:
30 = 0.5x + 10
So the equation in the form px + q = r is:
0.5x + 10 = 30
Cassandra measured her height as 63 inches. That is 6 inches less than 3 times her younger brother’s height. How tall is her younger brother?
Write an equation in the form px+q=r to represent this problem.
__x +__ = ___
Let's represent the height of Cassandra's younger brother with the variable "x".
Given that Cassandra measured her height as 63 inches, which is 6 inches less than 3 times her younger brother's height, we can write the equation:
63 = 3x - 6
So the equation in the form px + q = r is:
3x - 6 = 63
Anthony got a job babysitting. Each hour he works he will be paid $8.00. As a bonus, he will earn an additional $1.50 per hour for each child he watches. If his total hourly rate is $12.50, how many children does he watch?

___x + ___= ___
Let's represent the number of children Anthony watches with the variable "x".
Given that Anthony earns $8.00 per hour for his base rate and an additional $1.50 per hour for each child he watches, we can write the equation:
$8.00 + $1.50x = $12.50
So the equation in the form px + q = r is:
1.50x + 8 = 12.50
Susan read 17 pages today. That is 8 pages fewer than 13 of the pages she read yesterday. How many pages did she read yesterday?(1 point)
Let's represent the number of pages Susan read yesterday with the variable "x".
Given that Susan read 17 pages today, which is 8 pages fewer than 13 times the number of pages she read yesterday, we can write the equation:
17 = 13x - 8
So the equation in the form px + q = r is:
13x - 8 = 17
Karen measured her height as 59 inches. That is 27 inches more than half her older sister’s height. How tall is her older sister?
Let's represent the height of Karen's older sister with the variable "x".
Given that Karen measured her height as 59 inches, which is 27 inches more than half her older sister's height, we can write the equation:
59 = (0.5 * x) + 27
So the equation in the form px + q = r is:
(0.5 * x) + 27 = 59
