Answer:
1 cm
Step-by-step explanation:
We know that the formula for perimeter is<u> 2(l+w) or l+l+w+w</u>
We know that the height is 5 cm so that means <em><u>w= 5</u></em> also that there is 5 cm on both sides of the rectangle. So 5+5=10 so that means that the length of the rectangle is <em><u>1 cm</u></em> if you add the length together you 2 when you add the width you get 10. <em>10+2=12.</em>
Answer:

Step-by-step explanation:
From the question we are told that:
Slant Height of Kite 
Angle
Since Emma,The Kite and Andrew forms a right angle triangle
Generally the equation for distance between Andrew from Emma is mathematically given by



B-(-7)= -1
First negative multiply by negative is POSITIVE.
So: B+7= -1
Subtract 7 from both sides
B= -7-1
B= -8.
Answer: -8.
To Check Answer: Plug in the variable of B in the original equation.
So: -8-(-7)= -1
-8+7= -1
-1= -1
If the Solution works out the answer is right.
Answer:
adult $8.00
child $5.50
Step-by-step explanation:
Let the price of 1 adult ticket = x.
Let the price of 1 child ticket = y.
2x + 4y = 38
3x + 3y = 40.5
Multiply the first equation by 3. Multiply the second equation by -2. Then add them.
6x + 12y = 114
(+) -6x - 6y = -81
-----------------------------
6y = 33
y = 33/6
y = 5.5
2x + 4y = 38
2x + 4(5.5) = 38
2x + 22 = 38
2x = 16
x = 8
