Answer:
67.5
Step-by-step explanation:
this gives you the basis of the problem, 2 pages every 3 minutes, so that means that you have to divide 45 by 2, this will give you 22.5
then you multiply by 3 because 22.5 is how many sets of 2 Ella has to read, and if we remember every set of 2 pages takes 3 minutes, so 22.5 times 3 is 67.5, but if you want the answer in time it would be 67 minutes and 30 seconds because a minute is 60 seconds and half of that is 30
Answer:
Cost to a rent a snorkel , Cost on 10 rent snorkel
Step-by-step explanation:
Given,
Tourist spend on rent snorkel and fin=
10 snorkel and 12 pairs of fin
Let the cost to rent a snorkel be =x
and cost of a pair of fin is =y
x=3y (given condition)
Cost of a pair of fin=
Cost of rent a snorkel
Total cost of a rent snorkel
=
The answer is x=2
Remember, first add/substract the like terms, in this case 6x-10x to get -4x. Then, add 8x to negative 8x to cancel it out and do the same thing to -4x. Do this with all your terms and you should get 4x=8. Then divide both sides by 4 to get x=2.
