Formula of Trapezoid
Area= (b1+b2)/2*h
Area= (10+28)/2 * 23
Area= 38/2 * 23
Area= 19*23
= 437
Hope this helps!
Answer:
(X,Y) is (20,10) so that mean he made 10 bucks and sold 20 cups
Step-by-step explanation:
If the Length is 11 and the Width is 3 that makes the area 33. Now if you want all possible answers less than 33 then:
L: W: A:
11cm 3cm = 33cm
10cm 2cm = 20cm
9cm 1cm = 9cm
Now that's as low as you can get with whole numbers.
Answer:
12
Step-by-step explanation:
Answer: there are eight bicycles and 7 tricycles.
Step-by-step explanation:
Let x represent the number of bicycles that are there.
Let y represent the number of tricycles that are there.
There are a total of 15 bicycles and tricycles. This means that
x + y = 15
A bicycle has 2 wheels and a tricycle has 3 wheels. There are 37 wheels all together if we count them up. This means that
2x + 3y = 37- - - - - - - - - - - - - 1
Substituting x = 15 - y into equation 1, it becomes
2(15 - y) + 3y = 37
30 - 2y + 3y = 37
- 2y + 3y = 37 - 30
y = 7
x = 15 - y = 15 - 7
x = 8
