Hmm try 192.5 I think that’s right
15 = ½ (7x-6)
distribute ½ into parentheses
15 = ½(7x) - ½(6)
15 = ⁷/₂x - 3
multiply by 2
30 = 7x -6
subtract +6 to both side
30 + 6 = 7x
36 = 7x
devide 7 to both side
36
------ = x
7
Answer:
12(2y^2)^1/2
Step-by-step explanation:
you could just do trial and error if your calculator can do cube root
<span>cross Products Property should be:
10 * K = 8 * 7
10k = 56
k = 56/10
k=5.6</span>
Expand it so the expression would equal
5x^2+11x+2=-1
move the negative one over by adding one to both sides
5x^2+11x+3=0
then do the quadratic formula
x=-b+/- (√(b^2-4ac))/2a
where b = 11 a=5 and c=3
