I can only do number 1 sorry :(
4x+y=2x-y what you have to do is sort the numbers into x and y so it becomes 4x - 2x = -y -y. (Remember when it crosses the = it becomes minus!) Then solve it to get 2x = -2y = 3      so x is 0.66 and y is -0.66 I guess?
I am probably wrong because I am not good at algebra but good at other stuff

a ceramic bowl weighs 340 grams when empty. it is then filled with sugar. one tablespoon of sugar weighs 12.5 grams. write an eq
wel

Answer:

Total Weight of Bowl W = 340 + (12.5\timesT) grams

Step-by-step explanation:

Given

Weight of Ceramic Bowl = 340 grams

1 table Spoon of Sugar Weighs = 12.5 grams

So T table Spoon of Sugar Weighs = 12.5\timesT

Total Weight of Bowl W = Weight of Ceramic Bowl + Weighs of T table Spoon of Sugar Weighs

Total Weight of Bowl W = 340+ (12.5\timesT)grams

this afternoon dan left school, rode the bus 11/12 of a mile, and then walked 1/3 of a mile to get home. how much farther did da
nika2105 [10]

Dan rode 7/12 miles farther than walk after school.

<h3>What is a fraction?</h3>

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.

To compare both the fractions we will make the denominators similar and then subtract them to know the distance.

So the walking distance is 1/3 miles

This is also equal to 4/12 miles. (By multiplying both denominator and numerator with 4)

Now subtract 11/12 and 4/12

11/12-4/12 = 7/12 miles.

Therefore, Dan rode 7/12 miles farther than walk after school.

Simplify the problem below.
marta [7]

To solve this problem, we first must rewrite each term in the form k times a^n so that we can compute the multiplication afterwards.  To do this, we must remember that the square root of a is equivalent to a^(1/2) and that variables in the denominator have negative exponents.  Using this knowledge, we can rewrite the given expression as:

a^(1/2) * (2a² - 4a^(-1))

Now, we must recall that when terms with the same base are multiplied together, we must add the exponents when simplifying.  This step is shown below.

2a^(1/2 + 2) - 4a^(1/2 - 1)

The next step is to perform the addition of the exponents and obtain our final answer.

2a^(5/2) - 4a^(-1/2)

The above expression is your final answer.  

Hope this helps!
