Julius has three times as many stamps in his collection as his friends Liam has 10 stamps in his collection. Julius has 87 stamps in his collection. How many stamps does Mario have in his collection? The equation 3(x + 10) = 87 models this situation. Which choice shows the sequence of operations needed to solve this problem using both arithmetic and algebra?

you should at least use a calculater

step-by-step explanation:

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

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.
