the answer is 1
Step-by-step explanation:
Answer:
x=8a
Step-by-step explanation:
(3/a) x - 4 = 20
add 4 to both sides
(3/a) x = 24
Divide by 3/a
x = 24 / (3/a)
Use KCF (keep change flip)
x = (24/1) x (a/3)
x = 24a / 3
simplify
x = 8a
Answer:
it has increased by 1/2 so the scale factor would either be 3/2 or 1.5 or something
Step-by-step explanation:
4a-2=a+4
+2 to both sides
4a=a+6
-a from both sides
3a=6
I think I already answered it to you from the same question you asked earlier.
But anyways, the answer is in the image below and the steps are also in one of the images too.
Hope this helps! :)
