Answer:
-6 + 3x = -9

-----------------------------

And 6 to both sides:

-----------------------------

3x = -3

-----------------------------

Divide by 3 on both sides:

-----------------------------

x = -1

-----------------------------

**Answer: x = -1**

-----------------------------

-----------------------------

And 6 to both sides:

-----------------------------

3x = -3

-----------------------------

Divide by 3 on both sides:

-----------------------------

x = -1

Work out the percentage change to 2 decimal places when a price of £70 is increased to £99.

Use the binomial theorem to expand the expression :(3x + y)^5 and simplify.(b) find the middle term in the expansion of(1/x+√x)^4 and simplify your unswer.(c) determine the coefficient of x^11 in the expansion of (x^2 +1/x)^10, simplify your answer.

What is a linear function?

If you had 12 pieces of licorice to share equally among 5 people, how much 5 licorice would each person get? Show your thinking clearly using pictures, words and/or numbers.

This is how much VAT is charged on certain items

as a percentage of the item's cost.

Before VAT is added, Simon pays 12p per unit of

electricity plus a fixed charge of £87 per year.

How much does Simon pay in VAT if he uses 3000 units of electricity in one year?

er hour

Shane and Space

Simon will pay £18 in VAT for using 3000 units of **electricity** in one year.

The **VAT rate** for gas and electric is 5%.

Therefore, Simon will pay VAT on his electricity usage.

Let's calculate Simon's annual **electricity****cost** without VAT:

Cost per unit of electricity = 12p

= £0.12

**Number of units **used in one year = 3000

**Electricity****cost** without VAT = Cost per unit × Number of units

= £0.12 × 3000

= £360

Now, let's calculate the **VAT amount:**

VAT rate = 5% = 0.05

VAT amount = **Electricity****cost** without VAT × VAT rate

= £360 × 0.05

= £18

Therefore, Simon will pay £18 in VAT for using 3000 units of **electricity** in one year.

I don’t know the answer but help this man

Answer:

Step-by-step explanation:

The assumptions include:

The samples from each population must be independent of one another: this was adequately met.

The populations from which the samples are taken must be normally distributed: this was not talked about

The population standard deviations must be known: not known

or the sample sizes must be large (i.e. n1≥30 and n2≥30: true

The validity conditions for a two-sample z-test/interval were not all adequately met

The answer would be 7
