Answer:
width = 18 cm
Step-by-step explanation:
perimeter of rectangle = 2(length + width)
then:
90 = 2(27+w)
90/2 = 27+w
w = width
45 = 27+w
45 - 27 = w
18 = w
Check:
90 = 2(27+18)
90 =2*45 =
Answer:
13.1 (3sf)
Step-by-step explanation:
14 ^2 - 5^2 = 171

Each guest should get 144 cookies. This is because there are 432 cookies, and three guests. 432/3 = 144. :D Hope I helped!
Set up the ratios as proportional fractions:

We can simplify the first fraction to make the problem easier. Both the numerator and denominator of the first fraction can be divided by 3:


Both fractions now have the same denominator. Since both fractions have to equal each other, the numerators will also be the same. Therefore,
x = 4.
Hello, seems like you need help. Glad to help you.
To solve a slope with 2 given points, you must use the following equation:
-> Make sure to put the x on the top!
Plug the points into the equation.
2+6/-3-4
The slope will be 8/-7.
Hope this helped you out.
