Answer:
The length of the rectangle is 6 ft while the width is 3 ft.
Step-by-step explanation:
The formula for finding the area of a rectangle is
<em> </em><em> </em><em> </em><em> </em><em>area = width x </em><em>length</em><em> </em> and vice versa
lets substitute the numbers that we already know
18 = <em>w</em> x <em> </em><em> </em><em>2w</em>
We know from our times tables that 2 times 9 equals 18, and also that 3 times 6 equals 18.
6 is two times 3, so that works out!! Lets give it a try
18 = 3 x 3(2)
18 = 3 x 6
18 = 18 !!!
and we are done!

Answer:
The another word for magnitude is size
The answer would be 7/3. You would divide them both by 3. You just divide them by the same number to the point were you cant divide both by the same number anymore. For example 18/9 you can divide it by 2 to get 2.
8x-5=27
8x=32
x=4
Color it red!
1. Add 5 to both sides (combine like terms)
2. divide both sides by 8
3. You get your answer!!
Answer:
There would be 10 quarters and 23 dimes.
Step-by-step explanation:
There are generally two methods to solving this type of problem. (1) is guess and check, where you try different amounts of dimes and quarters in combinations of 33 coins until you reach an amount of $4.80. However, we can also solve the problem algebraically using two equations and two variables. In this case, 'd' = amount of dimes and 'q' = amount of quarters. We know that there are 33 total coins, or d + q = 33. We also know that the amount of the coins is $4.80, or .10d + .25q = 4.80. Solving the first equation for 'q', we get q = 33 - d. We can then substitute this expression for 'd' in the second equation to solve for d: .10d + .25(33 - d) = 4.80 or .10d + 8.25 - .25d = 4.80. Combining like terms and using inverse operations, first subtraction then division, we get d = 23. If there are 23 dimes, then there must be 10 quarters, for a total of 33 coins or $2.30 in dimes and $2.50 in quarters.
