You and some friends are playing a friendly online Role Playing Game. You download the basic game onto your 2 Gigabyte USB Flash Drive. The game used Gigabyte of space. You also want to add your friends’ mods onto the same USB Flash Drive. Each individual mod uses of a Gigabyte. Trevor believes there is room to save 15 mods. Mark thinks there is only enough room to save 10 mods. Use your mathematical reasoning to justify who is right and why. How many friends’ mods can ,t on the USB Flash Drive?

step-by-step explanation:

x = 12

y = 1

for the points!

hello!

to begin with, we're given that on earth, a rock weighs 20 pounds, and while on jupiter, that same rock weighs 42 pounds. now, we're trying to find the weight of a rock that weighs 10.5 pounds on earth, on jupiter.

to solve this, first, set up a proportion, cross-multiply, and solve it algebraically.

setting up the proportion is the hardest and the most confusing part of the problem, but it's simple.

if on earth, the rock weighs 20 lbs, and on jupiter it weighs 42 lbs, our first part of our proportion is 20/42 lbs. the second part has to be equal to each other. this means that 10.5 has to be on the numerator of the fraction, and x, the value we're trying to find, has to be on the denominator. remember that the rock weighs 10.5 lbs on earth, and we're trying to find the weight of it on jupiter (which is x).

20/42 = 10.5/x

next, you would cross-multiply.

20x = 42(10.5)

20x = 441

now, solve it algebraically by using division.

x = 22.05 lbs

this can be rounded to 22.1 lbs.

therefore, the weight of the rock on jupiter is 22.1 lbs, the fourth choice.
