Kora has 2 graham crackers and its enough for 1 s'mores. how many s'mores would kora make if she had 20 graham crackers?

10 s'mores

Step-by-step explanation:

c = crackers

s = s'mores

2c = 1s          

· 10   · 10     Multiplying both sides by the same number results in equality.

20c = 10s

20 graham crackers makes 10 s'mores.

Hope this helps!

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
