Answer:
11.55 m^2
Step-by-step explanation:
The area is 11.55 bc the area of a triangle is A =1/2*b*h
4.2*1/2*5.5= 11.55
4x - y = 5 --> 4x = y + 5
substitute
4x + 4y = -4
(y + 5) + 4y = -4
5y + 5 = -4
5y = -9
y = -1.8
solve x
4x = y + 5 = -1.8 + 5 = 3.2
x = 3.2/4 = 0.8
Let n be the sum of all 6 numbers:
In the 1st case n/6 = 41 ==> n =246
in the 2nd case n'/5 = 46===> n' =230, the unknown number is n-n' =246-230
= 16
You move the decimal 6 places to the right: 1986000
