Are slopes just for people who ski? No, they’re everywhere! Take a look around you. They’re in skateboard ramps, roller coasters, accessibility ramps on buildings, loading ramps on the backs of trucks, and even in the angle of a plane taking off or landing. A. Find an example of a slope in real life. Your example can be from the Internet, videos, magazines, newspapers, or right outside your window. Take a picture or a screenshot, or create a drawing, of your example. Put this in a PowerPoint slide. Next to your image, create a graph of the slope. You do not have to be exact. Just estimate what you think the slope should be. Create a post with your slide. Explain your graph and describe the real-life example that it is based on. Example: This is my new skateboard ramp. It is approximately 11 ft long by 8 ft tall. B. Go to another student’s post and write the equation for that student's line in point-slope form, standard form, or slope-intercept form. Explain your reason for choosing that form. C. Respond to replies to your own post. Covert the equation that was written about your graph to another form. Be sure to check back regularly to participate in the discussion with your fellow students and teacher.

Eva is at a sushi restaurant. She ordered 2 pieces of squid for a total of $3.50, 1 piece of eel for $3.25, 3 pieces of tuna for a total of $6.75, and 4 pieces of crab for $8.00. Which list shows the unit cost of each pieces of sushi from least to greatest?

Answers

The price of each piece of sushi is required.

The cost of each piece of sushi from least to greatest is squid ($1.75), crab ($2), tuna ($2.75) and eel ($3.25)

$2\ \text{pieces of squid}=\$3.5\n\Rightarrow 1\ \text{piece of squid}=(3.5)/(2)=\$ 1.75$

1 piece of squid costs $1.75.

1 piece of eel costs $3.25.

$3\ \text{pieces of tuna}=\$6.75\n\Rightarrow 1\ \text{piece of tuna}=(6.75)/(3)=\$ 2.25$

1 piece of tuna costs $2.75.

$4\ \text{pieces of crab}=\$8\n\Rightarrow 1\ \text{piece of crab}=(8)/(4)=\$ 2$

1 piece of crab costs $2.

2 pieces of squid = $3.50
Therefore 1 piece of squid = $1.75 (3.50÷2)

1 piece of eel = $3.25

3 pieces of tuna = $6.75
Therefore 1 piece of tuna = $2.25 (6.75÷3)

4 pieces of crab = $8.00
Therefore 1 piece of crab = $2 (8÷4)

Put them in order of price and you get

$1.75 , $2 , $2.25 , $3.25
squid,crab,tuna,eel

Can someone answer this for me pls and thank you

x in terms of b:

-2(bx - 5) = 16

-2bx + 10 = 16

-2bx = 6

x = 6 / -2b

x = -3/b

--------------------------------

when b = 3 then

-2(3x - 5) = 16

-6x + 10 = 16

-6x = 6

x = -1

Answer

The value of x in terms of b is -3/b

The value of x when b is 3 is -1

Jenna was 4 4/6 feet tall last year. This year she is 5 2/6 feet tall. How many feet did Jenna grow in the past year

Answers

You want to subtract the heights. 5 2/6-4 4/6=5 1/3-4 2/3=2/3.

You could turn the mixed fractions into improper fractions so 4 4/6 would become 28/6 and 5 2/6 would become 32/6. Then you can subtract 32/6 by 28/6 which would be 4/6 simplified into 2/3
