Answer:

  see below

Step-by-step explanation:

The problem is set up properly.

The factor of x was not properly multiplied by the first two terms of the trinomial. Terms were not combined correctly.

The proper multiplication and combining of terms is shown in the attachment. The green diagonal lines show the like terms that need to be combined to form the result.

8x-11+5x+2x+6=180 what is the measurement for x.
Verizon [17]

I assume you're looking for the value of x?

Combine like terms: 8x+5x+2x-11+6=180 -> 15x-5=180

Add 5 to both sides: 15x=185

Divide both sides by 15: x=12 1/3

So x is 12 1/3 or 37/3

Hope this helped!

£2300 is invested for 4 years at 5% per year simple interest. Work out the total interest
Hatshy [7]

Answer: £460

Step-by-step explanation:

Use this formula to find the total interest I=\frac{P*R*T}{100}

I stands for interest, P is principal, R is rate, and T is time.

Principle = £2300

Rate = 5%

Time = 4 years

\frac{2,300*5*4}{100} =\frac{46,000}{100} =460

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! :-)

Here are The ingredients For makeing fish pie for 6 people.180g flour 240 g fish 80g butter 4 eggs 180 ml milk.
GenaCL600 [577]

The amount of ingredients are needed:

<u>For 2 people: </u>Flour = 60 g, Fish = 80 g, Butter = 26\frac{2}{3} g, Eggs = 2 eggs, Milk = 60 ml

<u>For 15 people:</u>Flour = 450 g, Fish =  600 g, Butter  = 200 g, Eggs  = 10 eggs, Milk = 450 ml

Step-by-step explanation:

Given,

For 6 people following things are needed:

Flour = 180 g

Fish = 240 g

Butter = 80 g

Eggs = 4  

Milk = 180 ml

To find the amount of ingredients for a) 2 people b) 15 people

Now,

a) <u>For 2 people</u>

Since the number of people decreased by \frac{1}{3}rd times

The amount of ingredients will be decreased by \frac{1}{3} times

So, following this are needed:

Flour = 180×\frac{1}{3} = 60 g

Fish = 240×\frac{1}{3} = 80 g

Butter = 80×\frac{1}{3} = 26\frac{2}{3} g

Eggs = 4×\frac{1}{3} = 1\frac{1}{3} = 2 eggs

Milk = 180×\frac{1}{3} = 60 ml

b) <u>For 15 people</u>

Since the number of people increased by \frac{5}{2}th times

The amount of ingredients will be decreased by \frac{5}{2}th times

So, following this are needed:

Flour = 180× \frac{5}{2}= 450 g

Fish = 240× \frac{5}{2} = 600 g

Butter = 80× \frac{5}{2} = 200 g

Eggs = 4× \frac{5}{2} = 10 eggs

Milk = 180× \frac{5}{2} = 450 ml
