Answer:
y=8/3
Step-by-step explanation:
x=y-3
4x+2y=2
4(y-3)+2y=2
4y-12+2y=2
6y-12=2
6y=16
y=16/6=8/3
Answer:
<h2>204 units²</h2>
Step-by-step explanation:
It's a rectangle. Therefore the opposite sides are congruent.
We have the equation:
2x + 4 = 12 <em>subtract 4 from both sides</em>
2x = 8 <em>divide both sides by 2</em>
x = 4
Put the value of x to the expression 4x + 1:
4(4) + 1 = 16 + 1 = 17
Therefore we have the rectangle with dimesions 17 × 12.
The area of the rectangle:
A = (17)(12) = 204
Answer:
1/21.
Step-by-step explanation:
There are 9 digits and the total number of permutations of 3 from 9 is 9P3
= 9!/6! = 504.
There are 4 even digits so the number of permutations of 3 from these 4 is 4! (4-3)! = 4*3*2 = 24.
So the required probability = 24/504
= 1/21.
