Answer:
x = 20
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
9x = 180 ( divide both sides by 9 )
x = 20
Answer:
x = 48.
Step-by-step explanation:
If AE is 921, then EC is equivalent to that. First, you subtract 9 from 921, then divide by nineteen to get your answer: x = 48.
Answer:
100 x 2 x10x5
Step-by-step explanation:
1st: -2*2^(1-1) = -2*1 = -2
4th: -2*2^(4-1) = -2 *8 = -16
8th = -2*2^(8-1) = -2*128 = -256
Last choice is correct
Since we're given y, we can substitute y into the first euqation...
-2x+3(3x+4)=19
-2x+9x+12=19
7x=7
x=1
hope this helps :D brainliest pls
