The equation of a line is y = 50x. Then the slope of the line is 50 meters per minute.

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

Jenna can swim 150 meters in 3 minutes.

If you graph this with minutes on the X-axis and meters on the Y-axis.

Then the slope of the line will be

m = 150 / 3

m = 50 mters per minute

Then the equation will be

y = 50x

Square Root of Decimals:

Two websites I recommend are;

Khan Academy (basic and seems pointless but it actually can help)

https://www.cuemath.com/algebra/square-root-of-decimals/ or Cuemath.com

Those are the two websites I used when I was learning decimals and they helped me. Cuemath lists multiple ways to figure it out so I'd recommend that one first.

Answer:

1/5, 4/5, 5/5

Step-by-step explanation:

1/5 is 20%

4/5 is 80%

5/5 is 100%

Hey there!

“Put the fraction in least to greatest 1/5, 5/5, and 4/5”

Given numbers:

• 1/5

• 5/5

• 4/5

• We can make this EASIER to solve by converting your given fraction(s) in decimals (and maybe percentages)

• 1/5 = 0.2 = 20%

• 5/5 = 1 = 100%

• 4/5 = 0.80 = 80%

• So now that we got that out of the way, we have your answer

Answer: 1/5 , 4/5 , 5/5 ☑️

Good luck on your assignment and enjoy your day!

Answer: distributing

2(6x + 6) is 12x + 12

16x - 8 is 8(2x - 1)

3(x - 2) is 3x - 6

3(4x + 4) is 12x + 12

2x + 6 is 2(x + 3)

4(x + 3) is 12x + 12

Step-by-step explanation:

Distribute the number in front of the parenthesis to the numbers inside the parenthesis .

for example: 3(x-2)

3 times x = 3x

3 times -2= -6

answer: 3x - 6

Answer:

8 and 64

Step-by-step explanation:

32/8 = 4

64/16 = 4

Answer:

1:4

2:8

8:32

16:64

Step-by-step explanation:

The constant of proportionality is 1:4. Whatever number is on the right has to  be 4 times greater than the number on the left for it to be proportional. I divided 32 by 4 to get 8 on the first one, and I multiplied 16 by 4 on the second one to get 64.

Answer:

63 houses have been sold this year.

Step-by-step explanation:

There are 81 houses in the community. If 7/9 are sold this year, then all you have to do is multiplication.

In this case, you would multiply 81 by 7/9 to get your answer.

81/1 x 7/9:

Cancel out the 9 and the 81. Then the denominator will be 1 x 1 and the numerator would be 7 x 9. It would be 63 (7x9=63) over 1 (1x1=1) which is just 63. Make sure to include units.
