Answer and explanation:
<h2>X</h2>
3x + 6y = 180 <em>Use the original expression to find x</em>
3x = 180 - 6y <em>Subtract 6y by both sides</em>
<em>Divide by 3 to get x</em>
x = 60 - 3y
<h2>Y</h2>
x = 60 - 3y <em>Use the new expression to find y</em>
x - 60 = - 3y <em>Subtract 60 by both sides</em>
<em>Divide by -3 to get y</em>
Answer:
Step-by-step explanation:
In the given sequence, the terms are increasing in arithmetic progression. The common difference, d between successive terms is 2
The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = 1
d = 2
Therefore, the expression for the general term for the sequence is
Tn = 1 + 2(n - 1)
Answer:
6.5 cm
Step-by-step explanation:
Here, <em>the tangent line squared is equal to the secant line times the secant line outside the circle</em>.
That is <em>20.2² = 14.7 * (14.7 + 2x)</em> --> it is 2x because the secant goes through <em>the whole circle</em>.
Simplify: <em>408.04 = 216.09 + 29.4x</em>
Subtract: <em>191.95 = 29.4x</em>
Divide: <em>x = 6.528911565</em> ≈ 6.5 cm
Answer: 144 inches.
Step-by-step explanation:
1. To solve this problem you must remember the formula for calculate the perimeter of a rectangle, which is shown below:
Where 
is the lenght and 
is the width.
2. You know the perimeter and the width, then you can solve for the length, as following:

813,60 = ?%.1800
?/100.1800=813,60
?=813,60/18
?=45,2
