Step-by-step explanation:

1.  We can make an equation out of this...

    3x+3=48

    x is the age of Geoff which is what we are trying to find out

   

    We have to add 3 to both sides of the equation

    3x+3=48

         -3   -3

     ________

    we end up with 3x=45

     we then have to divide 3 by both sides because its the opposite of                

     multipling

Apartment buildings are required to have a fire extinguisher (extintor de incendios) every 600 feet. If a building has a total of 13,500 feet, how many fire extinguishers are needed?

Answers

Given:

Apartment buildings are required to have a fire extinguisher every 600 feet.

Height of building = 13,500 feet

To find:

The number of fire extinguishers are needed.

Solution:

Building needs a fire extinguisher every 600 feet.

Height of building = 13,500 feet

So, required number of fire extinguishers is

[tex]n=\dfrac{\text{Total height of building}}{600}[/tex]

[tex]n=\dfrac{13500}{600}[/tex]

[tex]n=\dfrac{135}{6}[/tex]

[tex]n=22.5[/tex]

Number of fire extinguishers cannot be negative.

[tex]n\approx 23[/tex]

Therefore, 23 number of fire extinguishers are needed.

Myra gets paid at home for doing extra chores. Last week, she did 5 loads of laundry and 8 loads of dishes, and her parents paid her $18. The week before, she finished 4 loads of laundry and 6 loads of dishes, earning a total of $14. How much does Myra earn for completing each type of chore?

Answers

Answer: Laundry = $2

Dishes= $1

Step-by-step explanation:

Let the amount paid for doing laundry be x

Let the amount paid for doing dishes be y.

Based on the information in the question, this can be formed in an equation as:

5x + 8y = 18 ..... i

4x + 6y = 14 ...... ii

Multiply equation i by 4

Multiply equation ii by 5

20x + 32y = 72 ...... iii

20x + 30y = 70 ...... iv

Subtract iv from iii

2y = 2

y = 2/2 = 1

Dishes cost $1

Since 5x + 8y = 18

5x + 8(1) = 18

5x = 18 - 8

5x = 10

x = 2

Laundry cost $2

Answer:

The expression x² + 8x + 7 can be factored out as (x + 7)(x + 1).

Step-by-step explanation:

You can see how this factors by looking at the last term, and the coefficient of the second term.  You need to find two numbers that multiply to make seven, and add to make eight.

Because seven is a prime number, this becomes very easy.  If this works at all, the numbers must be seven and one.

And lo, if you check, seven and one do indeed add up to be eight, so that's what we need to use.  Let's do it:

x² + 8x + 7

= x² + x + 7x + 7

= x(x + 1) + 7(x + 1)

= (x + 7)(x + 1)

Regular tickets cost 34.50 and vip tickets cost 78.50 a total of 810 tickets were sold, and a total ticket sales were 29,045. The equation 34.50r + 78.50 (810-r)= 29,045 can be used to determine the number of regular tickets r sold to the concert. How many of each type of ticket were sold?

Answers

Answer:Number of regular tickets=785

Number of VIP tickets=25

Step-by-step explanation:

Step 1

Cost of Regular tickets=34.50

Costs VIP tickets =78.50

Total tickets sold =810

Cost of both rockets sold=29,045

Using the the given equation that 34.50r + 78.50 (810-r)= 29,045 to determine the number of regular tickets, we have that

Step 2---Solving

34.50r + 78.50 (810-r)= 29,045

34.50+63,585 - 78.50r=29,045

63585-29045=78.50r-34.50r

34,540=44r

r=34540/44

r=785=Number of regular tickets

Number of regular tickets+Number of VIP tickets =810

Number of VIP tickets=810-785=25

Which of the following equations best represents the line of best fit for the data in the scatterplot?

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have the line of best fit for the data in the scatterplot.

The line passes through the points -

(0, - 1) and (2, 0).

Then, the slope will be -

m = 1/2

and the [y] - intercept is -1. So the equation that best represents the line of best fit is -

y = (1/2)x - 1

Therefore, the equation that best represents the line of best fit is -

y = (1/2)x - 1

Another way to think of this is 8 - 4 = 4.

When using 8, Z must equal 4.

Take this information to the left hand column.

8 - Z = Z

We know Z equals 4 so plug this information in. Is it correct?

Mortgage loan of $46,000.00.
Interest rate is 5 percent.
Monthly payment is $269.10.
How much of the first monthly payment is for interest?

Answers

Answer: $191.67

Step-by-step explanation:

When paying back mortgages, the monthly payment has two components: an interest payment component and a principal repayment component.

The interest payment component is based on the total amount of debt still to be paid at the time and the principal repayment component is the rest of the payment after the interest has been deducted.

This interest is in a yearly rate so should be combined to a monthly rate as the payments are monthly:

= 5% / 12

= 5/12%

Interest = Mortgage remaining * interest rate

= 46,000 *  5/12%

= $191.67
