Your answer should be 12+16x
X=hot dogs
y=potato chips
5x+2y=14.5
4x+5y=15.00
solving the system of equations
20x+8y=58 by multiplying the first equation by 4
20x+25y=75 by multiplying the second equation by 5
17y=17--->y=1 by subtracting equation 2 from 1
substituting in one of the equations
4x+5=15--->4x=10--->x=10/4=5/2=2.5
It’s proportional because it has a common rate. the 200 square foot room multiplied by the $3 for each square foot would be 600 and same with the 300 square foot house that costs $900. it has a common factor or rate
47 1/2 divided by 50 1/3
= 95/2 …………. 151/3
= 95/2 times by 3/151
= 285/302 of an hour.
0.9437 as a decimal.
Which is 56.6 minutes.
If the angle is x we have
cos x = 9/15 = 0.6
x = 53 degrees
So it's false.
