Answer:

74/15

Step-by-step explanation:

\frac{3}{4}x - 3 = \frac{7}{10}

to remove fractions multiply each side of equation by 40

3/4x(40) - 3 = 7/10(40)

120/4x - 120 = 280/10

simplify:

30x - 120 = 28

add 120 to each side to get:

30x = 148

x = 148/30 or 74/15 simplified

It can be written as -5/1 or -5.

Hope this helps!

vekshin1

Answer:

133 ft

Step-by-step explanation:

Given in the question,

length of the rectangle = 31 ft

width of the rectangle= 20 ft

diameter of semicircle = 20 ft

radius of semicircle = 20/2 ft = 10 ft

Formula to use:

<h3>perimeter of rectangle + perimeter of semicircle</h3>

perimeter of rectangle = 2(l+w)

perimeter of semicircle = 1/2(2πr)

Plug values in the formula above

2(31 + 20) + 3.14(10)

133.4 ft

≈ 133 ft

a store advertises that customers can take 25%off the original price and then take an extra 10%off is this 35% of? explain
kow [346]
No, it is not 35% off... Let me explain.  Let's say the original price is $100 to make the math easy.  When you take 25% off then take an additional 10% off, the 10% is off of the discounted price, so

100 x 25% = 100 x .25 = 25 dollar discount
New price = $75

Now 10% off of $75
10% x 75 = .10 x 75 = $7.50 discount
New price = 75 - 7.50 = $67.50


Now, if you just took 35% off of $100

100 x 35% = 100 x .35 = $35 discount
New Price = 100 - 35 = $65

Bottom line... when you take an "extra" percentage off, you are taking a percentage of a smaller number, so the discount is not as big.
