Solve for d in the proportion.
d
2
=
20
4
d = ??
To solve for d, we can cross multiply:
d * 4 = 2 * 20
4d = 40
Divide both sides by 4:
d = 10
Solve for a in the proportion.
4
10
=
6
a
a =
To solve for a, we can cross multiply:
4 * a = 10 * 6
4a = 60
Divide both sides by 4:
a = 15
7
3
=
14
a
a =
To solve for a, we can cross multiply:
7 * a = 3 * 14
7a = 42
Divide both sides by 7:
a = 6
To solve for d in the proportion, you can cross-multiply and then solve for d. Here's how:
First, let's write the proportion:
d/2 = 20/4
Next, cross-multiply:
4 * d = 20 * 2
Simplifying the right side:
4d = 40
Now, divide both sides of the equation by 4 to isolate d:
d = 40/4
Simplifying further:
d = 10
Therefore, d equals 10.
