Question

Can you please answer this

Answer 1

13. 71.5=5.5u divide each side by 5.5 to solve for u
71.5/5.5=13 so u=13

14. 5/6x=5/14 to solve for x you divide both sides by 5/6.  But to divide fractions you multiply the reciprical.  So:
x=5/14*6/5=30/70 or 3/7

15. 44=t/11 multiply both sides by 11 to solve for t
484=t

16. 8.3=b/14 multiply both sides by 14 to solve for b
116.2=b

17. x/3= 15 multiply both sides by 3 to solve for x
x=45

18. 7.8x=23.4 divide both sides by 7.8 to solve for x
x=3

Answer 2

13) divide 71.5 by 5.5 to find the answer for u.
14) find the common denominator then divide like in the last one
15) multiply 11 by 44 to find t
16) multiply 14 by 8.3 to find b
17) multiply 3 by 15 to find x
18) divide 23.4 by 7.8 to find x
