Answer Z = -1/4
Step-by-step explanation:
-1/3+2z= -5/6
Add 1/3 to both sides
-1/3+2z+1/3 = -5/6+1/3
Simplify
2z=-1/2
Divide both sides by 2
2z/2 = -1/2/2
Simplify
z = -1/4
Answer:

Step-by-step explanation:
The cost is £79.76. Since the car covers 560 miles and 34.5 miles is travelled by one gallon. So, dividing 560 by 34.5 we get 16.23. Since 1 gallon is 4.55 litres, 16.23 gallons is 73.8465. Now the cost of petrol is £1.08 per litre. So, multiplying 73.8465 by £1.08 we have £79.76

Wow that's sad sir..
Hope it gets better ;-;
-3(2r+7)=3
distribute -3
-6r-21=3
add 21 to both sides, this causes the 21 on the left to cancel itself out.
-6r=24
divide each side by -6, this causes the -6 on the left side to cancel itself out.
r=-4
