Soz man i use the metric system
You can find a common denominator using the two denominators multiples.
Answer:
Do you mean:
(1+(2/3))j = 15
((3/3)+(2/3))j = 15
((3+2)/3)j = 15
(5/3)j = 15
j = 15 / (5/3)
j = 15 * (3/5)
j = 9
Step-by-step explanation:
0=65-10t-5t^2
now what you want to do is multiply a and c
-5(t^2+2t-13)
Now just find the zeros
About 6 times. 6.4 to be exact!
