Well we already know that the 36:100 is correct because it is the starting amount, to check the 18:50 50 is half of the 100 insects so you would divide 36 by 2 which gives you half of 36 which is 18 so we can check off 18:50 as correct. Idk about the final one but the other two are correct.
Answer:
x = −6
Explanation:
5x + 7y = -23
Y = -2x - 11
Substitute -2x - 11 for y in 5x + 7y = -23
5x + 7(−2x − 11) = −23
Simplify both sides of the equation
5x + 7(−2x − 11) = −23
5x + (7)(−2x ) + (7)(−11) = −23 (Distribute)
5x + −14x + −77 = −23
(5x + −14x) + (−77) = −23 (Combine Like Terms)
−9x + −77 = −23
−9x − 77 = −23
Add 77 to both sides
−9x − 77 + 77 = −23 + 77
−9x = 54
Divide both sides by -9
−9x / -9 = 54 / -9
x = -6

Answer:
Step-by-step explanation:
x^-y=1/(x^y) so 3t^-4=3/(t^4)
Dees nuts because it’s spleens it but yea
