9y+9x=27
x+y=3
<em><u /></em><u>Answer:</u> <em>x</em>+<em>y</em>=3
The orginal price is 72 because 52 plus 20 is 72 which should be the regular original price. if a middle schooler like me can do it im sure you can toooo
Just exactly as you graph any other function: List a bunch of values for 'x', find the value of the function for each one, and start graphing the points, until you have enough points to see the shape of the function, and can draw more of it without more points. When you do that, you'll discover that -cos (x-pi) is equal to cos (x).
Answer:
1,2,5 equal 32
Step-by-step explanation:
Answer:
Part 1: 30.42
Part 2: 33.598 (33.6)
Step-by-step explanation:
Part 1:
First you're going to start by subtracting 142 from 360 to get 218
Then you're going to divide 218 by 360 to get a rounded .61
Then you're going to multiply that by pi (3.14)
.61 x 3.14 = 1.9
Then you're going to square 4
4 x 4 = 16
Then multiply 1.9 x 16
Your answer should be 30.42
<u>Part 2: </u>
<u>Since it gives you the measurment you need, you're going to skip the subtracting and just divide 107 by 360</u>
<u>This gives you .3 (rounded)</u>
<u>Multiply by pi</u>
<u>.3 x 3.14 = .94</u>
<u>multiply by square of 6 (36)</u>
<u>.94 x 36 = 33.84</u>
<u>if you shove it all into a calculator without rounding inbetween at all you get 33.59</u>
