Ok since it's by 3

21 7
---- is equal to ----
24 9

Because 24 divided by 9 is 3 so you'll have to divide 21 by 3 and you got your answer 7:9

Missing pattern 24,21, blank 15 blank ,blank
never [62]
To figure out this pattern, let's see if there's a constant rule that this sequence follows.
From 24 to 21, you're subtracting 3.
Let's try n-3, and fill in the blanks as we go.
24 - 3 = 21.
21 - 3 = 18.
18 - 3 = 15.
15 - 3 = 12.
12 - 3 = 9.
It seems that n-3 works as a rule, so your rule is:
N-3.
The missing blanks are:
18, 12, and 9.
I hope this helps!

While rolling, a wheel with a diameter of 19/2 ft makes 133 revolutions. Find the distance that is traveled by the wheel. Use 22
mojhsa [17]
You just need to find the circumference (the outside of the wheel) and then multiply that by how many times it turned

circumference is d* pi so your diameter 19/2 times pi (22/7) is about 29.86 ft
times that by 133 and you get exactly 3971 feet

The steps below show the incomplete solution to find the value of x for the equation
mafiozo [28]
Step 1: 6x - 2x - 5 = -6 + 21 
Step 2: 6x - 2x - 5 = 15 
Step 3: 4x - 5 = 15 

The next step would be to add 5 to both sides of the equation. 
so Step 3: 4x - 5 = 15 .......add 5 to both sides would make 
Step 4: 4x = 20 
 
So after the next step you would have 4x = 20 

Hope this helps! :)

madam [21]

Answer:

Vertical and Supplementary

Step-by-step explanation:

Vertical:

each of the pairs of opposite angles made by two intersecting lines.

Supplementary:

Two Angles are Supplementary when they add up to 180 degrees. These two angles (140° and 40°) are Supplementary Angles, because they add up to 180°: Notice that together they make a straight angle. But the angles don't have to be together.
