Numerical expressions use numbers and algebraic expressions use variables.
San 13/15, John 69%, Phillip 12/18. When you divide 13/15 you'll get 86. When you divide 12/18 you'll get 66.
Answer:
Emma was right to say that both packages are close to 2 pounds.
If we round-off the weights of both to the nearest whole number we would get 2 pounds on both. We look at the the difference of both from 2 pounds we get the following:
2.36 - 2.0 = 0.36
2.09 - 2.0 = 0.09
The smaller the difference the closer it is to the base value. So we can say that the closest one is 2.0 pounds is the package that weighs 2.09 pounds.
The first answer is 25x + 45 = c
The second one is y=3x
Hopes this helps
