The answer is AB = 6.

External value x (external value + internal value) = 
External value x (external value + internal value) of the other side

Substitute, transpose, and simplify.

TA x (TA + AB) = TC x (TC + CD)
10 x (10 + (x + 2)) = 8 x (8 + 12)
120 + 10x = 160
10x = 40
x = 4

To find AB: x + 12; x = 4
AB = x + 2
AB = 4 + 2
AB = 6

vladimir1956 [14]
9/50 is close to 10/50 or 1/5 or 0.2
7/15 is close to 7/14 or 1/2 or 0.5
0.2 + 0.5 = 0.7
0.7 is closer to 0.5 than 1

Which diagram best shows how fraction bars can be used to evaluate 1/2 divided by 1/4?
Helga [31]

Answer:

the second one

Step-by-step explanation:

2 halves make a whole. 1/2 + 1/2

4 fourths make a whole. 1/4 + 1/4 + 1/4 + 1/4

a half of a fourth is an eighth. 1/4 ÷ 1/2 = 1/8

Pls explain how to solve it!
Sophie [7]

Answer:

a = jd

Step-by-step explanation:

We want to solve for a given that a/d = j

To do so we want to isolate a (get a by itself )

We can do this by using inverse operations.

We would want to get rid of the d

A is being divided by d.

The inverse of division is multiplication so to get rid of the d we multiply a/d by d but whatever we do to one side we must do to the other so we multiply both sides by d

a/d * d = a

j * d = jd

we are then left with a = jd

And we are done!
