Answer:
29/14
Step-by-step explanation:
Start by working out the LCM of these (or any common denominator). A common denominator for 4 and 7 is 28 cuz 4 x 7 = 28.
3/4 = 21/28
4/7 = 16/28
3/4 = 21/28
(21+16+21)/28 = 58/28 which can simplify to 29/14
5x+4=9 its an expression which is greater than 1 you can do almost any expression but it has to be more than one.
Hope this helps :D
Since there is a 4ft shadow from an 8ft tall telephone boot, and 4 is half than 8, then the lawn ornament that casts a 2ft shadow is 4ft tall. Hope this helps!
