Westkost [7]2 years ago
8 0

Answer:

This alot but ill help you with 2 of them to learn em

Step-by-step explanation:

1) 2x^2 +5 =167

Subtract the 5 from both sides to get the equation 2x² = 162

Then divide the 2 from both sides to get x² = 81, Then square root from both sides to get x= 9

6) 2(2y +4)²=72

Divide 2 from both sides to get (2y+4)²=36

Then square root that to get 2y+4 = 6

subtract 4 from both sides to get 2y =2

Then divide both sides from 2. Y=2

Calculate the VAT amount that is included in the R93,57 monthly flat rate for the UNMETERED residential area
Misha Larkins [42]

Answer: R12.20

Step-by-step explanation:

VAT in South Africa is 15% so if the flat rate is R93.57, the VAT amount can be found by finding the pre-tax flat rate:

93.57 = x + 0.15x

1.15x = 93.57

x = 93.57/1.15

x = R81.37

VAT is 15% of R81.37:

= 15% * 81.37

= R12.20
