What is 4 1/3 minus 2 3/4

1 answer:

5 0

What you are asking is
$4 \frac{1}{3} -2 \frac{3}{4}$
we need to make the fractions improper now,
$\frac{13}{3} - \frac{11}{4}$
now we need common denominators:
$\frac{52}{12} - \frac{33}{12}$
we get
$\frac{19}{12}$
OR
$1 \frac{7}{12}$

Answer: $\frac{6}{y^2-xy}-\frac{6}{x^2-xy}=\frac{6(x+y)}{xy(y-x)}$

Explanation:

Combining the fractions, we have:

$\begin{gathered} \frac{6(x^2-xy)-6(y^2-xy)}{(x^2-xy)(y^2-xy)} \\ \\ =\frac{6x^2-6xy-6y^2+6xy}{(x^2-xy)(y^2-xy)} \\ \\ =\frac{6x^2-6y^2}{x(x-y).y(y-x)} \\ \\ =\frac{6(x-y)(x+y)}{-xy(x-y)^2} \\ \\ =\frac{-6(x+y)}{xy(x-y)} \\ \\ =\frac{6(x+y)}{xy(y-x)} \end{gathered}$

PLEASEE HEELLLP!!! I'LL GIVE BRAINLIEST!

Amanda [17]

Answer:

x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96

Step-by-step explanation:

The two angles above the horizontal line form a linear pair, so they are supplementary. Their measures add to 180 deg. That let's you find the value of x.

28x - 7 + 24x + 18 = 180

52x + 11 = 180

52x = 169

x = 169/52

x = 3.25

Now use the lower left angle and the upper right angle. They are vertical angles, so they are congruent. That allows you to solve for y.

12y + 30 = 24x + 18

We know that x = 3.25.

12y + 30 = 24(3.25) + 18

12y + 30 = 78 + 18

12y = 66

y = 66/12

y = 5.5

I don't know what the problem is asking for since you don't show.

x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96

Christie sells lemonade in her driveway she spends $20 dollars on supplies lemons sugar and cups she can make enough lemonade fo

Rasek [7]

Answer:

Profit = $ 5

Step-by-step explanation:

Money spent on supplies = $ 20

Number of cups of lemonade sold by her = 100

Selling price for 1 cup of lemonade = 1 quarter = $ 0.25

∴ Selling price for 100 cups of lemonade = $0.25\times100=25$

So, Christie can make $ 25 from 100 cups of lemonade.

Profit made by her = Selling price - Money spent on supplied

= $ 25 - $ 20 = $ 5.
