Answer:
x=11
Step-by-step explanation:
First you need to make those numbers into an equation. So you will have 4x+4=48. First you have to get the 4 on the other side so you do the opposite of the symbol and subtract 4 from 48 to get 44. So now you have 4x=48. Now you do the opposite og multiplication so you divide 44 by 4 and you get 11. Hope this helped :) I would appreciate it if you made this brainiest answer

Answer:
175 ft
Step-by-step explanation:
From the question,
(a) ΔABC and ΔEDC are similar because all the angles in ΔABC is equal to the corresponding angles in ΔEDC.
I.e, ΔABC is equiangular to ΔEDC. (AAA).
(b) From the diagram.
for similar angle, ratio of corresponding sides are equal
100/d = 4x/7x
100/d = 4/7
where d = distance across the river
solve for d
d = (100×7)/4
d = 175 ft
225 divided by 15 equals 15. It will take you 15 hours to get to the 225th mile marker.
