Answer:
feet
Step-by-step explanation:
Well the perimeter is the sum of all sides that means
P= lenght + width + lenght + width
P=2(lenght + width)
so
Answer:
9cos(46x) + 9cos(12x)
Step-by-step explanation:
18cos(29x)cos(17x)
According to Product-Sum identities
cos(α)cos(β)= (1/2)[cos(α+β)+cos(α-β)]
Putting α=29x and β=17x in Product-Sum identity we get
= 18×(1/2)[cos(29x+17x)+cos(29x-1`7x)]
Dividing 18 by 2 we get 9
= 9[cos(46x)+cos(12x)]
Multiplying 9 with both the terms we get
= 9cos(46x)+9cos(12x)
1) x = 5y - 30
2) x = - 1.6y + 3.3
<em>im assuming these are 2 different questions</em>
<h3>
Explanation:</h3><h3>1)</h3>
Start with the equation:
x - 5y= -30
add 5y to both sides:
x = 5y - 30
Your answer is x = 5y - 30
<h3>2)</h3>
Start with the equation:
3x+5y=10
subtract 5y from both sides:
3x = -5y + 10
divide by 3 to get x singular
x = - 1.6y + 3.3
Your answer is x = - 1.6y + 3.3
Hope this helps :)
Elimination
2 ( 2x -y=5) multiply = 4x -2y=10
3x +2y=4
* add the X's and the 10 and 4 7x=14 * divide by 7 giving you
x=2
*and then plug back in
3(2) +2y =4
6 + 2y = 4
2y= -2
y= -1
the order pair is ( 2 , -1)
Converting 10 quarts to cups would be 40 cups
