Answer:
x = 8/3
y = 7/3
Step-by-step explanation:
In a parallelogram the diagonals bisect each other.
So 2x = y + 3
x + y = 5
Then you set them up to do combination/elimination to solve for the two variables.
2x-y = 3
Then you add the two equations together
3x = 8
Solve for x
x = 8/3
Then solve for y by plugging it into a equation
x + y = 5
8/3 + y = 5
8/3 - 5 = -y
8/3 - 15/3 = -y
-7/3 = -y
y = 7/3
Answer:
9/20 yes, 4/15 not. See below
Step-by-step explanation:
Pick 9/20 and multiply numerator and denominator by 5:
9/20 = 45/100
We know that if we divide a number by 100 we need to move the coma as two places left, so:
9/20 = 45/100 = 0.45
And this is a terminal decimal as we know where it ends.
On the other hand if we pick 4/15 let try to divide it (here I will do it 'manually'):
4 |_ 15
we can divide 4 by 15, so we use 40 and begin with a comma
40 |_ 15
0.
15 enters 2 times in 40 with a rest of 10, so:
40 |_ 15
30 0.2
100
100 divided by 15 is 6 and we have 10 as rest again, and again and again...
40 |_ 15
30 0.266.....
100
100
....
So, we will have 0.266666666666666 infinitely. The decimal for 4/15 is non terminating and is 0.26666666666666666...
Answer:
y = -2
Step-by-step explanation:
y - 2 = -4
add 2 to both sides
y - 2 + 2 = -4 + 2
y = -2
