The area of a rectangle is 44m2 , and the length of the rectangle is 3m
Grace [21]

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

Half a number increased by 10 is equal to 35 less than twice the number. What is the number?
faust18 [17]

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

Liz flips a coin 60 times. The coin lands heads up 42 times and tails up 18 times. Complete each statement. The theoretical prob
alukav5142 [94]

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%

Feel free to ask for more if needed or if you did not understand something.

The street sign shown is a regular hexagon with side lengths of (7.6x+10.4) centimeters. The perimeter of the sign is 737.28 cen
lutik1710 [3]

Answer:

Equation:

6(7.6x+10.4)=737.28

Solution:

x=14.8\ centimeters

Step-by-step explanation:

<u>Perimeter of a hexagon </u>

We are given the length of the side of a regular hexagon

l=7.6x+10.4\ centimeters

And we also know the perimeter of the hexagon is

P=737.28\ centimeters

The perimeter of a regular hexagon is 6 times its side, so

P=6l=6(7.6x+10.4)

The equation that will give the relation to solve for x is

6(7.6x+10.4)=737.28

Reducing

7.6x+10.4=122.88

7.6x=122.88-10.4=112.48

\displaystyle x=\frac{112.48}{7.6}

x=14.8\ centimeters

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
