We know that O is midpoint of BF, which means OF is equal to OB by definition of midpoint.
Also, angles FOE and BOA are congruent by vertical angles theorem. Angles B and F are congruent by given, both are right angles.
We can deduct that triangles EFO and ABO are congruent by ASA postulate of congruence.
<h2>From the congruence between triangles, we deduct that angles A and E are congruent.</h2>
Answer:
All of them except for the 3rd one
Step-by-step explanation:
2) 15 - 3x = 5(x + 4) - 8x
15 - 3x = 5x + 20 - 8x
15 - 3x ≠ -3x + 20
4) 2(x - 7) = 2x - 10
2x - 14 ≠ 2x - 10
1) 24x - 22 = -4(1 - 6x)
24x - 22 ≠ -4 + 24x
3) 12 - 2x = 6(2x + 2)
12 - 2x = 12x + 12
0 = 14x
0 = x, only one that has a solution
We know that
<span>Joey and Rita paint a room in 8 hours
so
100%----------> 8 hours
X%----------> 1 hour
x=100/8-----> 12.5%
that means
</span>Joey and Rita paint 12.5% of a room in 1 hour
Billy paint a room in 12 hours
so
100%----------> 12 hours
X %------------> 1 hour
x=100/12----> x=8.33 %
that means
Billy paint 8.33% of a room in 1 hour
i<span>f all three work together
then
All three paint (12.5%+8.33%) in 1 hour
20.83%------------> 1 hour
100%------------> x
x=100/20.83-----> x=4.8 hours
the answer is
4.8 hours</span>
Answer: 2/3
Explanation:
Rise over Run, count up how many units and to the right until you reach the second point
Answer:
(x+2) + x + (x+4) = 2(1/2) + 2(x+3)
Step-by-step explanation:
They are equal to each other and the rectangle has 2x more perimeter
The triangle would be divided in half from that rectangle.
Sorry If this is confusing I am not very good at explaining things.
