Answer: 3/14
Step-by-step explanation: you just multiply?
2 plus 2 equals 4 so then they almost finished two pizzas right there so you have 5 2/3
Answer:
height = 4 meters
h = 2A / ( a + b )
Step-by-step explanation:
Let A represent the area of the trapezoid, h, the height a, the length of one base and b, the length of the other base
Area of a trapezoid, A = ( a + b)* h / 2
Now let's slot in the given values
A= 18 sq meters
a = 3 meters
b = 6 meters
we have;
18 = ( 3 + 6 ) * h /2
18 = 9 * h /2
Cross multiply
18*2 = 9h
36 = 9h
divide both sides by the coefficient of h (9)
4 = h
therefore, h = 4 meters
To solve for h without substituting
From A = ( a + b )* h /2
cross multiply
2*A = ( a + b )* h
divide both sides by ( a + b )
2A / ( a + b ) = h
therefore,
h = 2A / ( a + b )
Answer:
x = 8/13
Step-by-step explanation:
6 - 3x - 3/5(15x + 20) = 7(2x/7 - 2) - x
6 - 3x - 9x - 12 = 2x - 14 - x
6 - 12 + 14 = 2x - x + 3x + 9x
8 = 13x
x = 8/13
