Answer:
$187.50 for shirts + The price for the hats.
Step-by-step explanation:
7.50 x 25 =the price for the shirts and 5 x K= the price for hats
K= how many camp counselors need hats.
in all add 187.50 and the price for the hats.
75% of students = 18
Divide by 3 to find 25% of students.
25% of students = 6
Add the two together or multiply the 25% of students by 4 to get the total number of students.
25% + 75% = 6 + 18 = 24 students
or
25%*4 = 6*4 = 24 students
Answer:
4. Infinitely many
Step-by-step explanation:
5x + 3(x − 1) = 10x − 2x − 3
5x+3x-3=8x-3
5x+3x-8x=3-3
0=0
x∈R
Answer:
x^2 -x -2 = (x -2)(x +1)
Step-by-step explanation:
To factor x^2 -x -2, you look for factors of -2 that have a sum of -1:
-2 = (-1)(2) = (1)(-2) . . . . . the latter pair has a sum of -1
Then these are the constants in the binomial factors:
x^2 -x -2 = (x +1)(x -2)

<em>Comment on the question</em>
The fact that x^2 +3x -4 is modeled with algebra tiles seems to be irrelevant to the question that is actually asked.
