1. No 1/5 is 0.2  5/5 is equal to 1, and 5/1 is equal to 5
2. If there are 50 states total and by 1795 15 states had become part, then the answer is 15/50, which could be simplified to 3/10

<span>No .. 1/5 is smaller that 5/5(which is equivalent to 1) then 5/1 is equivalent to 5
..and by 1795 there were 15 states so 15/50.</span>

Maurinko [17]

Answer:

The value of f(2) - g(7)=-58

Step-by-step explanation:

We have

f(x) = 3 ^ x - 7\\\\f(2) = 3 ^ 2 - 7\\\\=9-7\\\\=2\\\\g(x) = x ^ 2 + 11\\\\g(7) = 7 ^ 2 + 11\\\\=49+11\\\\=60\\\\f(2) - g(7)=2-60\\\\=-58

My mother is 12 years more than twice my age.after 8 years she will be 20 years less than three times my age...find my age and m
Mnenie [13.5K]
You are correct for the first part, you would be 16 and your Mom would be 44. After 8 years, you would be 24 and your mother would be 52. You solve the second part by adding 8 to 16 which equals 24. Then multiply 24 times 3 which equals 72. Lastly, subtract 20 from 72 to find your mother's new age. Which would be 52.

Hope this helps !

BRAINLIEST AVAILABLE!!!!<br><br> PLEASE HELP ME WITH THIS!!!<br> Thanks to all helpers!!!!!
larisa [96]

Answer: B

<u>Step-by-step explanation:</u>

-10x² + 12x - 9 = 0

a=-10, b=12, c=-9

x = \frac{-b+/-\sqrt{b^{2}-4ac}} {2a}

  = \frac{-12+/-\sqrt{12^{2}-4(-10)(-9)}} {2(-10)}

  = \frac{-12+/-\sqrt{144-360}} {-20}

  = \frac{-12+/-\sqrt{-216}} {-20}

  = \frac{-12} {-20} +/- \frac{\sqrt{-216}} {-20}

  = \frac{3} {5} +/- \frac{6i\sqrt{6}} {-20}

  = \frac{3} {5} +/- \frac{3i\sqrt{6}} {10}
