Answer:
R =
Step-by-step explanation:
I = ( multiply both sides by 100 to clear the fraction )
100I = PRT ( isolate R by dividing both sides by PT )
= R
A ladder leaning against a wall forms a triangle and exterior angles with the wall and the ground. What are the measures of the

Let roses be R and carnations be C
"in a ratio of 2 to 7" means that the ratio of R to C is 2 to 7, meaning you'll have to cross multiply to translate it algebraically
since C = 343 we plug 343 in :
ergo, she needs 98 roses
to make sure of the answer:
"ratio of 2 to 7" is technically a fraction =>
and since the ratio of the roses to the carnations is the same as we plug the values R = 98 and C=343:
