Answer:
a = 5
b = -4
c = -20
Step-by-step explanation:
Here, we want to express the given equation in the following form;
So we can have this as;
5x-4y-20 = 0
That means we have;
a as 5
b as -4
and c as -20
Let x = times in the pool
Let y = times in the basketball courts
42=3x+5y
x+y=12
Therefore y = 12-x
Subsitute for y
42 = 3x + 5(12-x)
42 = 3x + 60 -5x
Subtract 60
-18 = -2x
9 = x
The person used the pool 9 times.
You subtract 11 from 19 and then the answer is 8
Answer:
Step-by-step explanation:
Alright, lets get started.
The part of the diagonals are given as 0.9 m and 1.2 m.
The diagonals of rhombus intersect each other.
Hence the length of diagonals will be : 
and 
The formula of area of rhombus is : 
where p and q are the length of diagonals.
So plugging the values of diagonals in formula, the area will be :
Area = 
Area = 
Area =

Hope it will help :)
74,233 increased by 58,490 is 74,233 * 58,490 so its 4,341,888, 170. So 4 billion, 341 million, 888 thousand, 170.
Scientific notation is 4.34188817 * 10 to the 9th power.
