Plot the following fractions and decimals on the number line.
OLga [1]

Answer:

hmmmmmmmm, cool

well, here ya go

Step-by-step explanation:

0.7 is AKA 7/10, which is a little less than 3/4, AKA 0.75, so in between 3/4 and 1

1/3 is larger than 1/4 but smaller than 1/2, so prob somewhere in the middle of those two.

8/7, since the numerator is larger than the denominator, is larger than 1 by 1/7, so goes right in front of 1.

0.4, AKA 4/10,  is a little less than 1/2, AKA 0.5, but larger than 1/3, AKA 0.333333333(goes on forever) so it goes in the middle of those

0.125, AKA 1/8, is the smallest of the bunch, and it's half of 1/4, AKA 0.25. That means its dead last, half between 1/4 and 0.

5/6 is the largest, around 8.333333(more foreverness)/10, which is larger than 3/4, AKA 0.75, so it goes between that and 1.

So, for your final answer:

0---0.125---1/4---1/3---0.4---1/2---0.7---3/4---5/6---1---8/7

I am not sure if thats what your structure for the question is, so I hope that that order helps. i could also put it in all decimals if it helps,  or all fractions, so let me know in the comments.

Drag a statement or reason to each box to complete this proof.
ololo11 [35]

Answers:


1) -3(x + 8) = -21

2) Division Property of Equality

3) x + 8 = 7

4) Subtraction Property of Equality


Reasoning:


You are already given the equation, so that will be #1 in the Given.

#2 shows both sides being divided by -3, so you will put the Division Property of Equality.

#3 shows the Division Property after it is carried out, so you will put the equation after the division is done.

#4 shows you are subtracting 8 from both sides, so put the Subtraction Property of Equality.

Well we know these two angles are congruent, so we set their angles equal to each other.
5w - 69 = w + 3
4w = 72
w = 18
Now we plug w back into one of the equations, and then multiply whatever number we get by 2.
18 + 3 = 21
21 x 2 = 42
