X = 18 - 1/2 the answer is 18 of x/18
Answer:
Non Proportional
Step-by-step explanation:
Make a proportion:
For example say you want to test out how many bottles of water you can buy for $10
Proportion:
4 - 6
10 - ?
Solve: 10×6÷4=15
So technically, you could only get 15 bottles for $10. Therefore, this is a non proportional problem.
Answer:
It would be B.
Step-by-step explanation:
This is because adding a negative exponent onto a number is telling you how many times you have to divide it by. So in this case, it would be the equation 1 / 2^4 to solve it.
3x-5y=-3 original problem
3(1)-5y=-3 put 1 in the place of x and multiply
3-5y=-3 subtract 3 from both sides
-5y=-6 divide both sides by -5
y=possitive 6/5
