Hello!
Just multiply across:
4/5 * 20.5/1 = 4(20.5) / 5(1) = 82 / 5 = 16.4
So 4/5 of 20.5 is 16.4.
Hope this helps :))
To find the measure of THX we will set THX and XHV equal to each other.
6x + 5 = 8x - 15
6x + 20 = 8x
20 = 2x
10 = x
Now we can find the measure of THX by substituting in 10 for x,
6x + 5
6(10) + 5
60 + 5
65
THX is 65
Hope this helps :)
