\left(\dfrac{2}{5}x+\dfrac{5}{8}\right)+\left(\dfrac{1}{5}x-\dfrac{1}{4}\right)=\left(\dfrac{2}{5}x+\dfrac{1}{5}x\right)+\left(\dfrac{5}{8}-\dfrac{1}{4}\right)\\\\=\dfrac{2+1}{5}x+\left(\dfrac{5}{8}-\dfrac{1\cdot2}{4\cdot2}\right)=\dfrac{3}{5}x+\left(\dfrac{5}{8}-\dfrac{2}{8}\right)\\\\=\dfrac{3}{5}x+\dfrac{5-2}{8}=\boxed{\dfrac{3}{5}x+\dfrac{3}{8}}

riadik2000 [5.3K]

Answer:

to find the sale price, you need to find what 34% of 82 is.

82 x 0.34 = 27.88

subtract that from the original price

82 - 27.88 = $54.12

you could also multiply 82 by (1 - .34) to get the same answer

82 x (.66) = $54.12

sale price is $54.12

hope this helps:)

What is the solution to 5a-15+9a=3a+29
pogonyaev

5a-15+9a=3a+29

We simplify the equation to the form, which is simple to understand

5a-15+9a=3a+29

We move all terms containing a to the left and all other terms to the right.

+5a+9a-3a=+29+15

We simplify left and right side of the equation.

+11a=+44

We divide both sides of the equation by 11 to get a.

a=4
