28 tries. The ratio is 5:7, so once you multiply 5 by 4 to get 20, you do the same to 7 to get 28.
Answer:
(1.5, -13.5)
Step-by-step explanation:
Midpoint Formula: 
Simply plug in our coordinates into the formula:
x = (17 - 14)/2
x = 3/2
y = (-11 - 16)/2
y = -27/2
Answer:
x = 704/39 ( <----Fraction)
Step-by-step explanation:
28 squared minus 39x minus 80 equals 0
784-39x-80=0 evaluate the power
704-39x=0 Subtract the numbers
-39x=-704 move the constant to the right hand side and change it's sign
Divide on both side to get x = 704/39
you would just add both of them together so the weight would be 7.69 Ibs
complementary angles add up to 90°, so therefore we know that ∡A + ∡B = 90°, and also they are in a ratio of 3:6.
