Answer:
width=11/2
length=8
Step-by-step explanation:
44=(2w-3) x w <em>area for a rectangle (44) = the length (2w-3) times the width (w)</em>
44=2w^2 - 3w <em>distribute</em>
2w^2-3w-44 = 0 <em>subtract 44 from both sides</em>
(w+4)(2w-11) <em>factor</em>
width=11/2
(11/2 x 2) - 3
length = 8
Answer:
x=10
Step-by-step explanation:
x/2 + 10 = 35 - 2x
x/2 + 2x = 35 - 10
5x/2 = 25
5x = 25.2
5x = 50
x = 50/5
x = 10
Answer: The theoretical probability of the coin landing heads up is 0.7
Step-by-step explanation:
Hi, to answer this question we simply have to divide the number of times that the coin lands heads up (42 times) by the number of times that the coin was flipped:
Mathematically speaking:
42 /60 = 0.7 (decimal form)
The theoretical probability of the coin landing heads up is 0.7
For the or percentage form we simply multiply the result by 100:
0.7 (100) = 70%

Equation:
Solution:
Step-by-step explanation:
<u>Perimeter of a hexagon
</u>
We are given the length of the side of a regular hexagon
And we also know the perimeter of the hexagon is
The perimeter of a regular hexagon is 6 times its side, so
The equation that will give the relation to solve for x is
Reducing
Answer:
21
Step-by-step explanation:
8 5/12 + 6 2/3
8 5/12 + 6 8/12 = 14 13/12
14 13/12 = 15 1/12
15 1/12 + 5 11/12 = 20 12/12
20 12/12 = 21
