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

- i am not COMPLETELY sure, but from what i have learned i think it would the LAST three.

Answer:

Answer:

9.375 km/h

Step-by-step explanation:

192 - 3 minutes 12 seconds

500m - 0,5 kilometers

60 x 60 = 3600

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!

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.

I hope this helped love <3

Answer:

D

Step-by-step explanation:

the x (first number in the ordered pair) cant match with another x

in every other line, the x repeats which makes the function thing make a diagonal line instead. **khan academy explains it well btw**

Step-by-step explanation:

1. If you multiply 5*6 you would get 30. So 1. 30x. 2. If you add the like terms you would get 9x + 5y. 3. you can use the distrubitive property. 4. You have to find the LCM. And find the other factor and add the variable. I am sorry I will work on the other 2. Hope this helps, let me know if correct, and have a great day!!

Answer:

8 and 64

Step-by-step explanation:

4/1 = 4

8/2 = 4

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.

Step-by-step explanation:

The quotient of given numbers is 6.4.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Given that, dividend =70.4 and divisor=11.

The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.

Here, 70.4/11

= 6.4

Therefore, the quotient is 6.4.
