Step-by-step explanation:

Jack and beth are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of shiny wrapping paper. Jack sold 5 rolls of plain and 8 rolls of shiny for a total of $190. Beth sold of 5 rolls plain and 3 shiny for a total of $90. Find the cost of each roll of wrapping paper

Answers

Answer:

Cost of a roll of plain wrapping paper = $6

Cost of a roll of shiny wrapping paper = $20

Step-by-step explanation:

Let [tex]x[/tex] denotes cost of a roll of plain wrapping paper and [tex]y[/tex] denotes cost of roll of shiny wrapping paper.

Jack sold 5 rolls of plain and 8 rolls of shiny for a total of $190.

[tex]5x+8y=190\,\,\,(i)[/tex]

Beth sold of 5 rolls plain and 3 shiny for a total of $90.

[tex]5x+3y=90\,\,\,(ii)[/tex]

Subtract (ii) from (i).

[tex]8y-3y=190-90\\5y=100\\y=20[/tex]

Put [tex]y=20[/tex] in (ii)

[tex]5x+3(20)=90\\5x+60=90\\5x=90-60\\5x=30\\x=6[/tex]

Therefore,

Cost of a roll of plain wrapping paper = $6

Cost of a roll of shiny wrapping paper = $20

An 18% tip is left on a $65 dinner bill. 5% tax is added (before tip). What is the total paid?

Answers

Y=

Answers

Answer:

y = 210,000(1.055)^t

Step-by-step explanation:

Initial population: p = 210,000

Annual growth rate: 5.5% = 0.055

Number of years: t

Population in year t: y

y = p(1 + r)^t

y = 210,000(1 + 0.055)^t

y = 210,000(1.055)^t

The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?

Answers

Answer:

x = -4, 4

Step-by-step explanation:

Given graph in the attachment represents the function y = f(x)

Real solutions of the function means all the points where the curve of the graph either touches or crosses the x-axis.

Since, graph of the function touches and crosses at x = -4 and x = 4

Therefore, all real solutions of the function are x = -4 and x = 4

HELP

Answers

Answer:

Y = 1

X= -1

Step-by-step explanation:

Y is 3 so x is 2 and if y = x then x - 1 would be one and then that would make y = 1

X is 2 - y which is 3 will equal -1

Answer:

Step-by-step explanation:

2x – 3y = -5.........(i)

у = х – 1................(ii)

Multiply equation (ii) by 3,

3у = 3х – 3.......(iii)

Add (i) and (iii)

2x – 3y = -5

-3x + 3y = – 3

-x = -8

x = 8

put the value of x in eq (ii)

у = х – 1

у = 8 – 1

y = 7

THANK YOU.

The greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.

What is LCM?

It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.

It is given that:

The GCF of 14x and 18xy

As we know, GCF is the greatest common factor.

The greatest common factor of 14 and 18 or

GCF(14, 18) = 2

And the greatest common factor of GCF of x and xy

= x

the greatest common factor of 14x and 18xy is:

= 2x

Thus, the greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.
