Answers

If the slope is the same but they have 2 different y-intercepts, the lines are parallel.

Remember that y=mx+b, where m is slope and b is y-int, y and x are variables.

Example:

y=3x+5 and y=3x+1

Parallel because the slope is the same.

y=3x-2 and y=2x-1

NOT parallel because the slope is different.

Jacob helped his grandma peel potatoes for the family's dinner. His grandma peeled 4 times as many potatoes as Jacob peeled.If Jacob's grandma peeled 16 potatoes, how many potatoes did they peel altogether?

Answers

Answer: 20

Step-by-step explanation:

Jacob's grandma peeled 4 times as many potatoes as he did, so if she peeled  16, you would divide 16 by 4 and conclude that Jacob peeled 4 potatoes. Then, you would add the 4 potatoes that he peeled to her 16. Hope this helps!

Jacob and his grandmother both peeled 20 potatoes.

What is the ratio?

A ratio is a numerical comparison of two numbers. A ratio represents the proportion of one object to another.

Given, Jacob's grandmother peeled four times as many potatoes as he did, therefore if she peeled 16, divide 16 by four to get that Jacob peeled four potatoes. Then you'd add the four peeled potatoes to her 16.

potato peeled by Jacob's grandmother = 16

potato peeled by Jacob = 4

Total potatoes peeled = 16 + 4 = 20

Therefore both Jacob and his grandmother peeled the sum of 20 potatoes together.

Paisley needs to order some new supplies for the restaurant where she works. The restaurant needs at least 587 glasses. There are currently 307 glasses. If each set on sale contains 20 glasses, which inequality can be used to determine the minimum number of sets of glasses Paisley should buy?

as a equation please

Answers

Answer:

The restaurant needs at least 587 glasses

587-307 = 280

each set contains 20 glasses

14 sets contain 280 glasses

let the minimum number of sets be x

x ≥ 14

The inequality represents the minimum number of sets of glasses Paisley should buy is 14 ≥ x.

The relationship between two or more expressions that is either greater or less than each other but not equal to each other is called inequality.

Given that:

Number of glasses the restaurant needs = 587

Number of glasses the restaurant has = 307

Since each set contains 20 glasses, the total number of glasses in "x" sets would be 20x.

The equation can be set as:

Total glasses needed ≥ Current glasses + Glasses in sets to buy

Substitute the values in the above inequality:

587 ≥ 307 + 20x

280 ≥ 20x

14 ≥ x

The inequality represents the minimum number of sets of glasses Paisley should buy is 14 ≥ x.
