Answer:
r = -1/3 and r = 3/5
Step-by-step explanation:
Given the expression 15r^2-6r-3 = -2r
collect the like terms
15r^2-6r+2r-3 = 0
15r^2-4r-3 = 0
Factorize
15r^2-9r+5r-3 = 0
3r(5r-3)+1(5r-3) = 0
(3r+1)(5r-3) = 0
3r+1 = 0 and 5r-3 = 0
3r = -1 and 5r = 3
r = -1/3 and r = 3/5
Nine hundred fifty four thousandths
The answer is p= .125 another way of putting it is 2/2.5
Answer:
8/17
Step-by-step explanation:
first find hypotenuse which is 34
then to get sine it is opposite/hypotenuse
opposite ÷ hypotenuse
16/34
8/17
First we move the term: 8x - 15x = 6 - 48
-7x = -42
Divide both sides by -7
x = 6
