*6. Five brothers each bought two hot dogs & a bag of chips. If the chips
cost $1.25, and the total was $22.75 what was the price of each hot dog? *
A. $1.35 per hot dog
B. $1.45 per hot dog
C. $1.55 per hot dog
D. $1.65 per hot dog

Answers

D- 1.65 per hot dog

Take the amount of the bag of chips which is 1.25 and multiply it by 5 because that’s how many people there are and they each bought one bag
1.25 x 5= 6.25
Next you want to subtract that amount from the total so we can just have the amount of money spent on hot dogs
22.27-6.25=16.50
Then you want to divide 16.50 by 5 because they all bought the same amount of hot dogs and this will get us to the amount of to hot dogs
16.50/5=3.30
Finally you want to divide 3.30 by 2 which will get us the price for 1 hot dog
3.30/2=1.65

There you go!!
Answer is D $1.65 per hot dog

Of the 645 students in the freshman class, 85 are left-handed. About what percentage of the students are left-handed? Round to the nearest tenth.

About % of the freshman class are left-handed.

Answers

Answer:

About 13% of the freshman class are left-handed

Step-by-step explanation:

To find the percentage of a whole you need to divide the part by the whole number (85/645 = 0.1316), then you round to the nearest tenth (0.13) and change it into a percentage by moving the decimal point 2 numbers to the right. (13%)

what is the equation of the line?​

Answers

Answer:

x=3

Step-by-step explanation:

the x axis is going across by 2 and the number in between 2 and 4 is 3 and the line is going through the x axis hence the equation of the line is  x=3

Answer:

[tex]x=3[/tex]

Step-by-step explanation:

Normally, linear equations would be written in slope-intercept form, [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis). However, linear equations for horizontal or vertical lines are organized differently.

Here, we're given a vertical line. Vertical lines are written like [tex]x=d[/tex], where [tex]d[/tex] is the x-intercept, or the value of x when the line crosses the x-axis.

From the graph, we can tell that the x-intercept is 3. Therefore, our equation would be [tex]x=3[/tex].

I hope this helps!

Answer: Yes

Step-by-step explanation:

From the question, we are informed that Ed's birthday is less than 16 days

away and that Ann writes the inequality

d< 16, where d equals the number

of days, to represent this.

The inequality d < 16 is correct as it explains that the number of days left is less than 16.

Answer:

Ann is correct because d is less than 16.

Step-by-step explanation:

Ed's Birthday is *less than 16* days away so d<16

Answers

Answer:

Y = 5 - 2/x

Step-by-step explanation:

Answer:

x=2

Step-by-step explanation:

You want to isolate x so first, you have to multiply the whole equation by 1/4 so it will look like 1/4(2y+4/x=10). Simplify this to get 1/2y+x=5/2. You want to isolate x, so you have to subtract 1/2 from each side, this will make the equation x=5/2-1/2. Simplify this to get x=4/2 which can also be simplified to x=2. Therefore, the answer is x=2

What is the area of the shaded quadrilateral? (see attachment)

Answers

Answer:

B. 36 [tex]cm^{2}[/tex]

Step-by-step explanation:

The shaded quadrilateral has a shape of a trapezium.

Area of a trapezium = [tex]\frac{1}{2}[/tex](a + b)h

where: a is the side length parallel to the base, b is the base and h is the height.

The height of the figure = 11 - (4 + 1)

                                        = 11 - 5

                                        = 6

The height of the figure is 6 cm.

The length of its base = 11 - (1 + 2)

                                    = 11 - 3

                                    = 8

The length of its base is 8 cm.

The length of the side parallel to base = 11 - (4 + 3)

                                     = 11 - 7

                                     = 4

The parallel side length to base is 4 cm.

Area of quadrilateral = [tex]\frac{1}{2}[/tex](a + b)h

                                     = [tex]\frac{1}{2}[/tex](4 + 8)6

                                    = 12 x 3

                                    = 36

Area of quadrilateral = 36 [tex]cm^{2}[/tex]

Solve the simultaneous equations
4x + 5y = 9
4x - 2y = 2

Answers

Answer:

x = 1 and y = 1

Step-by-step explanation:

Let's solve your system by substitution.

4x + 5y = 9 ; 4x − 2y = 2

- Solve 4x + 5y = 9 for x:

4x + 5y = 9

4x + 5y + − 5y = 9 + − 5y (Add -5y to both sides)

4x = − 5y + 9

[tex]\frac{4}{x} = \frac{- 5y + 9}{4}[/tex]

[tex]x = \frac{- 5}{4} y + \frac{9}{4}[/tex]  

Then Substitute [tex]\frac{- 5}{4} y + \frac{9}{4}[/tex]  for x in 4x - 2y = 2

4x − 2y = 2

4([tex]\frac{- 5}{4} y + \frac{9}{4}[/tex]) − 2y = 2

− 7y + 9 = 2 (Simplify both sides of the equation)

− 7y + 9 + − 9 = 2 + − 9 (Add -9 to both sides)

− 7y = − 7

[tex]\frac{- 7y}{- 7} = \frac{- 7}{- 7}[/tex]  (Divide both sides by -7)

y = 1

Substitute 1 for y in x = [tex]\frac{- 5}{4} y + \frac{9}{4}[/tex]

[tex]x = \frac{- 5}{4} y + \frac{9}{4}[/tex]

[tex]x = \frac{- 5}{4} (1) + \frac{9}{4}[/tex]

x = 1

So, x = 1 and y = 1

Answers

Answer:

B

Step-by-step explanation:

they want us to find the equation in slope intercept form

which is y= mx + b

where m = slope and b = y intercept

the slope is change in y over change in x

as y goes up 1 x goes up 1 so the slope is 1 or m=1

the y intercept is at point (0,1)

so the y intercept is 1

now we add it all together and get that the equation Is

y=x+1

Answers

Answer:

Step-by-step explanation:

I have put my answer in slope-intercept form as that is usually the most common. Inputing the slope as "m" into the equation "y=mx+b" and substituting the x and y coordinates given to find b gives the equation "2=(1/4)(-4)+b" By solving this we get "b=3" to finish the equation.
