The sum of 8 and a number is 8 + x. Now multiply that by 4 to get 4(8 + x). The word "is the same as" means "equals" 59 more than the number, which means we add 59 to the unknown we have called x. So our equation now looks something like this (exactly like this, actually): 4(8 + x) = x + 59. Simplifying a bit gives us 32 + 4x = x + 59. 3x = 27 and x = 9. The number is 9!

Answer:
3. 2kg/m 4. 1.524 meters
Step-by-step explanation:
3. 20g/cm to kg/m.
(20g÷1000g)kg ÷ (1cm÷100cm)m
1/50kg ÷ 1/100m
1/50 x 100/1=2kg/m
4. 1nch=2.54cm.
1foot=12inches
5feet= 5x12
=60inches
1inch=2.54cm
60nches=60×2.54
=152.4cm
100cm=1m
152.4cm=152.4÷100
=1.524m
thus 5 feet=1.524meers
