Answer:

1. [tex]3 (20+4x)[/tex]

2. [tex]60 + 12x[/tex]

Step-by-step explanation:

1. Let's just focus on one person at the moment. One of the friends bought a single shirt for $20, and 4 shirts that cost x dollars. Therefore, a single person's expense can be shown as:

[tex]20 + 4x[/tex]

Where x is the number of shirts the person bought.

Each of the three friends had the exact same expenses too, so we multiply this by three:

[tex]3 (20+4x)[/tex]

2. Simplifying the above equation just means multiplying each term in the parentheses by the 3 outside it, so 3 times 20 is 60, and 4x time 3 is 12x. Therefore, the simplified expression is:

[tex]60 + 12x[/tex]

Sherry make 16 pies in 12.9 hours.

What is Division method?

Division method is used to distributing a group of things into equal parts.

Given that;

Sherry can make 5 pies in 4 hours.

Now,

Since, Sherry can make 5 pies in 4 hours.

So, Sherry can make 1 pies in = 4/5 hours.

Thus, Sherry can make 16 pies in = 16 x 4/5 hours.

                                                    = 64/5 hours

                                                    = 12.9 hours

So, Sherry make 16 pies in 12.9 hours.

Step-by-step explanation:

Answer:

14,275

1013

Step-by-step explanation:

1: To get the population in the year 2001 we would have to multiply 4500 by 1.08. To get the population in 2002 we would have to multiply: 4500(1.08)(1.08) or 4500(1.08)^2  

Therefore you can write the following equation

4500(1.08)ⁿ where n is the number of years

we need is in 2015 and so n=15 so we have

4500(1.08)¹⁵=14274.5 which you should probably round to 14275

The second one is very similar to the first

to get from 1990 to 1991 you would multiply 5000*.93

so our equation would be

5000(.93)ⁿ where n is the number of years

1990-2012 is 22 so we have

5000(.93)²²=1012.96 which rounds to 1013

A) £3264000.

. £1000 increased by 5000% =£51,000

. £51,000×64=£3264000

B) £6528000

. £2000 increased by 5000% =£102,000

. £102,000×64=£6528000

Answer:

a.) 26< a 28  

b.) 4

Step-by-step explanation:

a.) After looking at the age in years collum you can notice that all of ages have a difference of 2. With this you can infer that the missing number is 28.

b.) To find the mean add up all the numbers in the frequency column.

3+2+7+8+0=20

Divide that by the amount of numbers. There are 5 numbers so 20/5=4.

Answer:

Scale factor = [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Given question is incomplete; find the question in the attachment.

Scale factor = [tex]\frac{\text{Dimension of image}}{\text{Corresponding dimension of preimage}}[/tex]

Scale factor = [tex]\frac{\text{Dimension of image rectangle B}}{\text{Corresponding dimension of preimage rectangle A}}[/tex]

From the figure attached,

Length of rectangle B = [tex]\frac{20}{3}[/tex]

Length of rectangle A =  20

Scale factor = [tex]\frac{\frac{10}{3}}{10}[/tex]

                    = [tex]\frac{\frac{10}{3}}{10}[/tex]

                    = [tex]\frac{1}{3}[/tex]

Therefore, image rectangle A is dilated with by a scale factor of [tex]\frac{1}{3}[/tex].

Answer:

Third side = 8.34 cm

Step-by-step explanation:

Given that,

The perimeter of a triangle, P = 22 cm

One side of a triangle, b = 9 cm

The area of the triangle, A = 20.976 cm²

The formula for the area of a triangle is given by :

[tex]A=\dfrac{1}{2}\times b\times h\\\\h=\dfrac{2A}{b}\\\\h=\dfrac{2\times 20.976}{9}\\\\h=4.66\ cm[/tex]

Perimeter = Sum of all sides

9 cm + 4.66 cm + x = 22

x = 22 - 13.66

x = 8.34 cm

So, the third side of the triangle is 8.34 cm.

Answer:

See below.

Step-by-step explanation:

1) Two equations are equivalent if they have the same solutions.

2) As long as two expressions [tex]a[/tex] and [tex]b[/tex] are equal, so [tex]a=b[/tex], adding the same value for both sides still makes the equation true, so

[tex]a = b[/tex]

[tex]a + c = b + c[/tex] is true.

3) As long as two expressions [tex]a[/tex] and [tex]b[/tex] are equal, so [tex]a=b[/tex], subtracting the same value for both sides still makes the equation true, so

[tex]a = b[/tex]

[tex]a - c = b - c[/tex] is true.

Step-by-step explanation:

the answer is 2y=16x+14

The equations that could be the other equation are y = 8x - 7 and y = -8x + 7.

If the system of equations has no solution, then the other equation must not have the same slope-intercept form as the first equation.

The slope-intercept form of the equation y = 8x + 7 is y = mx + b, where m is the slope and b is the y-intercept. Thus, the slope of the first equation is 8 and the y-intercept is 7.

Now let's check each of the given equations to see which one could be the other equation.

2y = 16x + 14

Rewriting this equation in slope-intercept form, we get y = 8x + 7, which is the same as the first equation. Therefore, this equation cannot be the other equation.

y = 8x – 7

This equation has the same slope as the first equation but a different y-intercept. Therefore, it represents a different line and could be the other equation.

y = –8x + 7

This equation has a slope that is the negative of the slope of the first equation, so it represents a different line. Therefore, it could be the other equation.

2y = −16x − 14

Rewriting this equation in slope-intercept form, we get y = -8x - 7, which has the same slope as the first equation but a different y-intercept. Therefore, it represents a different line and could be the other equation.

Answer:

minutes

Step-by-step explanation:

Let x be the time in the beginning (in minutes).

Given: The track team is trying to reduce their time for a relay race.

First they reduce their time by t^1=2.1 minutes.

Then they are able to reduce that time by t^2=1/10

If their final time is 3.96 minutes, then

X - t^1  - t^2 = 3.96

=> X = 3.96 + t^1 + t^2

=> X = 3.96 + 2.1 + 1/10

=>  X = 6.16

Answer:

The answer should be choice B.
