Answer:
Find other solutions in explanation
x = 250
y = 1750
Step-by-step explanation:
x = cost per copybook
y = cost per pen
2. Sum of the cost of 4 copy books and 3 pen is equal to 7750
3.)
2x+y=2750 - - (1)
4x + 3y = 7750 - - - (2)
From (1)
y = 2750 - 2x
Substitute y = 2750 - 2x into (2)
4x + 3(2750 - 2x) = 7750
4x + 8250 - 6x = 7750
-2x = - 500
x = 500/2
x = 250
y = 2750 - 2(500)
y = 2750 - 1000
y = 1750
The problem with this conclusion is that there is missing data.
In order for there to be a conclusion you must test it multiple times in order to see how certain the conclusion is.
Good Luck! :)

Answer:
Step-by-step explanation:
Synthetic division is one way to determine whether or not a given number is a root of the quadratic. x^2 − 12x − 20 can be rewritten as x^2 - 12x + 36 - 36 - 20, or (x - 6)^2 - 56, which does not have integer solutions:
(x - 6)^2 - 56 = 0 becomes (x - 6)^2 = 56, which works out to x - 6 = ± 2√14.
None of the possible roots suggested in this problem turns out to be an actual root.
correct response: PRIME
Answer:
show how you know .. :D good rhyme
Step-by-step explanation:
park = 4" x 6" ( inches) small park
but one inch = 30 miles ooh big park
4*30 X 6*30
120 X 180 miles... like a big game range? :? very big
since we only have 6 square inches to fit the map into... then.. what size of map would fit? what size equals 6 inches? 2 x 3 ? hmm yes that's 6
soooo shrink the 4" x 6" to 2"x 3" so the scale needs to double or
1 inch = 60 miles
2"*60 x 3"*60 = 120 x 180 miles.. looks good try that :)
