<u>Answer</u>:
Length of the envelope = 14
Width of the envelope = 5.6
<u>Step-by-step explanation:</u>
Let the width of the rectangle be x
Then the length of the rectangle will be 
Also the length of the plastic band to cover the front and back of the envolpe = 
To cover one side th band required is
=>
=>
=>
=>
=>39.4
We know that the perimeter of the rectangle is
=> 2( L + B) = 
=> 2( 
) = 19.7
=> 2( 
=> 
=> 
=> 
Now length of the envelope =
=> 
=> 
=> 14
Answer:
<u>The correct answer is A. 14 x + 6 y = 10. Negative 14 x minus 35 y = 77</u>
Step-by-step explanation:
Let's find out the constants to eliminate the x terms
7 x + 3 y = 5
2 x + 5 y = negative 11
Let's multiply the first equation by 2 and the second one by -7, this way:
2 * (7 x + 3 y = 5)
-7 * (2 x + 5 y = negative 11)
14x + 6y = 10
-14x - 35y = 77
<u>The correct answer is A. 14 x + 6 y = 10. Negative 14 x minus 35 y = 77</u>
To find the x-intersept, just set y = 0 into the equation, then solve it for x:
-2x + 5 * 0 = -10
-2x + 0 = -10
-2x = -10
x = (-10)/(-2)
x = 5 <----- this is the answer.
I hope this helps. =)
Answer:
x=55
Step-by-step explanation:
2x-7=103
2x=103+7
2x=110
x=55
