Answer:
x = 5
Step-by-step explanation:
Since these are similar triangles all you need to do is figure out how much "x" has gotten smaller.
First take the line DE length (16) and divide it by line BC (8)
16 / 8 = 2
Now divide line BD by 2
10 / 2 = 5
x = 5
Answer:
A=C/x-By/x
Step-by-step explanation:

Hey there! I’m happy to help!
Let’s use the variable g to represent the girls. This ratio shows that there are twice as many boys as girls (boys=2g)We also see that there are 18 more boys that girls. Let’s set up an equation
g+18=2g
We subtract 18 from both sides
g=2g-18
We subtract 2g from both sides.
-g=-18
We divide both sides by -1
g=18
Therefore, there are eighteen girls.
I hope that this helps! Have a wonderful day!
Yes every integer is a rational number, since each integer can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
