How do you solve 2z - 31 = -9z + 24?
Schach [20]

2z−31=−9z+24

Add 9z to both sides.

2z−31+9z=−9z+24+9z

11z−31=24

 Add 31 to both sides.

11z−31+31=24+31

11z=55

Divide both sides by 11.

11z/11=55/11

z=5

Answer:

Each monthly payment is of £560.

Step-by-step explanation:

Sue buys a car costing £8000 plus 20% VAT?

She has to pay:

8000 plus 20% of tax. So

T = 8000 + 0.2*8000 = 9600

She pays £4000 deposit and then chooses to pay the balance in ten equal monthly payments.

4000 deposit, and then 9600 - 4000 = 5600 divided in ten equal monthly payments.

5600/10 = 560

Each monthly payment is of £560.

mr Goodwill [35]

Use the next convertion factors:

60 seconds are equal to 1 minute

60 minute are equal to 1 hour

24 hours are equal to 1 day in earth

9.98\times10^4s\cdot\frac{1\min}{60s}\cdot\frac{1h}{60\min}\cdot\frac{1\text{day}}{24h}\approx1.15\text{day}<h2>Then, there are approximately 1.15 earth days in a Mar's day</h2>
