Answer:
x = 4, 7
Step-by-step explanation:
We start off with the equation 
. from there, we can add 28 to both sides to get 
. From there, we have to factor the equation. In order to factor it, we have to ask ourselves what 2 numbers would add up to -11 and multiply to 28? In this case, the answer would be -7 and -4. So, we get the equation (x-7)(x-4) = 0. Then, we set each part of the equation = 0 to get the anwsers x = 4 and 7. Hope this helps!
Answer:
<h3>913x - 96</h3>
Step-by-step explanation:
Given
The expression of number of people entering on Saturdays = 508x-70
The expression of number of people entering on Sundays = 405x-26
total amount of people entering the theme park that weekend = Total entering on Saturday + total entering on Sunday
Substitute the expression;
total amount = 508x - 70 +(405x-26)
total amount = 508x+405x-70-26
total amount = 913x - 96
Hence the total amount of people entering the theme park that weekend is 913x - 96
Cd+e = 21
Cd + e - e = 21 - e
Cd = 21 - e
Cd/C = 21-e/C
d = 21-e/C.
Seven groups with 8 people in each group
Answer:
Quincy read 9 books.
Step-by-step explanation:
Work backwards. Samantha read three less books than Teresa (11-3=8). Ralph read half as many books as Samantha (8/2 = 4). Quincy read five more books than Ralph (4 + 5 = 9).
