Answer:
The perimeter of the rectangle is 54 meters.
Step-by-step explanation:
In order to find the perimeter of the rectangle, which is the sum of all the sides, we need to know not only the length, but also the width. The formula for area of a rectangle is A = length x width. Setting up an equation to find width 'w', we get: 162 = 18 x w. Using inverse operations, we divide both sides of the equation by 18 to get w = 9. Since we now know that w = 9 and l = 18, we can find the perimeter using the following equation: P = 2w + 2l or P= 2(9) + 2(18) or P=54 meters.
When multiplying fractions you multiply the denominators by the denominators and the numerators by the numerators
For example
4/5x 2/3
8/15
Answer:
x>=5/6
Step-by-step explanation:
She's practiced 2 1/3 hours already. Therefore, she has 1 2/3 hours left to practice. Let x be the minimum number of hours she needs to practice on each of the remaining two days.
Splitting up the remaining hours into two days, we get (5/3) divided by 2, which is 5/6 hours per day.
x is greater than or equal to 5/6 hours per day.
You have to find the difference between 4 1/2 and 1 7/8, in other words subtract those. MAKE SURE YOU SUBTRACT 4 1/2 MINUS 1 7/8, IF YOU DO IT THE OTHER WAY AROUND, IT WILL IMPACT YOUR ANSWER.
In order to subtract correctly, you have to make them common denominators.
