Answer:
X=20; pqr = 130°
Step-by-step explanation:
They key here is to notice that the instructions say that qs bisects pqr, meaning that it evenly cuts it into 2 pieces. So, to find x, you just solve for x in the equation 3x+5=2x+25. Then, you plug it back into either side of the equation, at which point, you should get 65. Since it is half of pqr, just double it to get your final answer of 130°
Hi <span>angelaatkinsonca1,
the answer would be 6.
Remember that to find the percentage of any number, you convert the percent to a numerical form and multiply:
10% = 0.10
2% = 0.02
37% = 0.37
and so forth.
So, in this case, 20% = 0.20
To find 20% of the number 30.00, you would just multiply the two numbers together:
30.00 x 0.20 = 6.000
or, just the number 6.
Hope this helps!
Good luck</span>

You can do this without the calculator
115 grams
after 1 half-life = 115 / 2 = 57.5 grams
after 2 half-lives = 28.75 grams
after 3 half-lives = 14.375 grams
after 4 half-lives = 7.1875 grams
after 5 half-lives = 3.59375 grams
after 6 half-lives = 1.796875 grams
