Answer: The correct answer should be 7.6128
If you do the problem correctly, you will get an answer of 7.6128. This is because there are 4 decimals places in the numbers that are being multiplied. This means that there will be 4 decimal places in the answer. If you have her work, we can find the mistake. It is probably that she counted the wrong number of places.
I think 10.5 is the right answer.
Answer:
the first problem is 85+10w=50+15w which is 5.4
the second is 150+2c=120+4c which is 45
Step-by-step explanation
so when writing equalities you first write the equation with the constant and variable that apply to the same category together. like in the first problem when Liz saved 85 dollars and saved 10 weekly. those numbers applied to one thing so they are put together. you do that for both categories. once you do that you then combine like terms, ( by the way terms are each of the quantities in a ratio, series, or mathematical expression.) so in the problem Liz has 10w and Amelia has 15w .these numbers are alike so you combine them to then get 25w. then you do the same to the constant (which is the number that is by itself) then you divide 135 by 25 to get 5.4=c.
in the second problem you write the equation with the constant and the variable that apply to the same category together. so the first category will be 150+2c which is studio 1 and then the second category will be 120+4c which is then studio 2. just like in the first problem you combine like terms ( the definition for terms is explained in the paragraph above in parentheses). one you combine the terms you should have 270=6c. one you have this divide 270 by 6 to then get 45=6.
Answer: hope the explanation helps. it helps if you include the choices that you could pick
Step-by-step explanation:
A=lw
A=12*10.5
A=(12+x)*10.5
A=126+10.5x
I would hope I would be your boring but it could be all of the above if she was a snob.
