Answer:
x=5
Step-by-step explanation:
I did math and ForGOt
N = d - 5
2n/(d + 16) = n/d - 1/3 n/d
2n/(d + 16) = 2/3 n/d Divide by 2n
1 / (d + 16) = 1/3 d
Here's the tricky part.
d + 16 = 3d the two denominators are equal. the numerators are both 1.
16 = 2d
d = 8
so the numerator is d - 5
n = 8 - 5
n = 3
Let's see if it checks out.
n = 3
d = 8
2*3 = 6
8 + 16 = 24
New fraction 6/24 = 1/4
(3/8 - 1/3 ) = 1/8
3/8 - 1/8 = 1/4 so it checks with the original conditions put on it.

Answer:
Step-by-step explanation:
∠D = ∠B {opposite angles of parallelogram are equal}
∠D = 40°
In ΔDCA
∠DCA + ∠D + ∠CAD = 180 {Angle sum property of triangle}
57 + 40 + ∠CAD = 180
97 + ∠CAD = 180
∠CAD= 180 - 97
∠CAD = 83°
Answer:
<u><em>A. x+y<10</em></u>
<u><em>B. x+y≤10</em></u>
Step-by-step explanation:
A is correct because they can be less than.
B is correct because there is less than or equal too of numbers of volunteers.
C, D, and E cannot be correct however, because that means that they can be over at any number. Therefore, these three would be incorrect.
