The solution set is (9.5, 3.5). Explanation: 9.5(2)+3.5(2) is the same as 19+7 which equals 26. These same numbers are used for x-y=6, which is 9.5-3.5=6.
If Rachel's total budget was n, then:
.45n=$76.5 divide both sides by .45
n=$76.5/.45
n=$170.00 Rachel's total budget.

Answer: 15 kg</h3>
==============================================
Work Shown:
KE = 480
v = 8
KE = (1/2)*m*v^2
480 = 0.5*m*8^2
480 = 0.5*m*64
480 = 0.5*64m
480 = 32m
32m = 480
m = 480/32
m = 15
The SI unit for mass is in kilograms
Also a joule is defined with kilograms since 1 J = 1 kg*m/s^2
1 joule is the amount of energy needed to move an object of mass 1 kg with an acceleration of 1 m/s^2
So this is why the mass m is in kilograms.
Three would fit cause 3 times 12 is 36 and 4 times 12 is 48 which would be too big
