Answer: 77 seeds
Step-by-step explanation:
Given: The germination rate for zinnia seeds =78%
Let x be the total number of seeds he planted, then
The seeds germinated= 78% of x
⇒The seeds germinated= 0.78x
If James wants 60 zinnia plants for his yard, then it will give the equation
Hence, he should plant 77 seeds .
Answer:
12a + .5B
B= -6a
a=.042B
1/2(6a+B)= 12a+.5B
1/2(6a+B)=0
-12a=.5B
-6a=B
12a=-.5B
I would say 6:12.
it is equivalent to 12:24 because 12/2= 6 and 24/2 = 12 so 6:12 is your answer!
