Answer:
5n + 25q = 200 - - - (1)
n = 5q - - - (2)
q = 40
n = 5(40) = 200
Step-by-step explanation:
Number of Nickels = n
Number of Quarters = q
$2.00 = $2 * 100 = 200 cent
Nickel = 5 cent
Quarter = 25 cent
5n + 25q = 200 - - - (1)
n = 5q - - - (2)
5(5q) + 25q = 200
25q + 25q = 200
50q = 200
q = 200/5
q = 40
n = 5(40) = 200
Answer:
The area of the triangle enclosed by the three points
A(1,1), B(1,4) and C(-3,4) in this question will be given by
|Ax ( By − Cy)+ Bx(Cy−Ay)+ Cx(Ay− By) |/2
=|1(4-4)+1(4-1)+-3(1-4)|/2=10/5= 5 sq. units
Answer:
x<4
Step-by-step explanation:
For this inequation:
3(x + 8) > 2 (2x + 10)
or 3x +24 > 4x +20
-4x+ 3x + 24> -4x +4x +20
and we have -x +24> 20
or -x +24 -24 > 20-24
-x >-4 and finally x < 4 ( multiple -1 for both sides, > change into <)
All real number x so that x< 4 is solution.
