a =
Step-by-step explanation:
4a -16 = a - 15
both left and right -a
then
4a - 16 -a = a - 15 -a
then
4a -a -16 = a -a -15
then
3a -16 = -15
both left and right + 16
then
3a -16 + 16 = -15 + 16
then
3a = 1
both left and right ÷3
then
3a ÷ 3 =1 ÷ 3
then
a =
Well 5=5
and 37/40
hmm, try to get that 40 into an nice number that is multiplule of 10
if we divide top and bottom by 4 that would work
9.25/10=92.5=100=925/1000=925 thousandths=0.925
so the decimal would be 5.925
