Answer:
Z= -4.6
Step-by-step explanation:
z/2-3/5=2/3z +6
you first find the LCM of both sides
LCM of 5 and 2 is 10 then LCM of 3 and 6 is 6
5z-6/10 = 4z+1/6
then you cross multiply
6(5z-6)=10(4z+1)
open the bracket
30z-36=40z+10
collect like terms
30z-40z=36+10
-10z=46
z= -46/10
= -4.6
For question 8, you'll have to calculate the price for three lamps and the sofa together. Take the total price of the items and multiply the percentage.
For question 9, the formula for simple interest is price(P) x rate(R) x time(T) / 100. Put in the information given:)
Answer:
