Answer:
the missing number is 2
Step-by-step explanation:
Left side is (733*5)*2 (please use * for multiplication, or · , but not X or x)
Right side is 733*5. Rewriting the expression this way makes it obvious that the missing number is 2.

Answer:
3 was subtractedboth sides were divided by 3both sides were multiplied by -3both sides were divided by -3Step-by-step explanation:
It looks like you have four different equations here.
As a rule, each step in the solution involves one of the properties of equality: addition, subtraction, multiplication, or division. These properties let you do the same thing (one of these operations) to both sides of the equation.
__
1. 10 − 6 x = 4 + 5x
7 -6x = 1 +5x . . . . 3 was subtracted from both sides*
__
2. 3 ( 4 x − 3 ) = − 15
4x -3 = -5 . . . . . both sides were divided by 3
__
3. 5x/-3=12/1
5x=-36 . . . . both sides were multiplied by -3
__
4. −3 ( 4 x − 3 ) = − 15
4x -3 = 5 . . . . both sides were divided by -3

* For this equation it would have been more useful to subtract 4 to get ...
6 -6x = 5x

A cylinder has a height of 18 millimeters and a radius of 18 millimeters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer:
18312.5mm³
Step-by-step explanation:
Given parameters:
Height of cylinder = 18mm
radius = 18mm
Unknown:
Volume of the cylinder = ?
Solution:
The volume of cylinder is given as;
Volume = π r ² h
Insert the given parameters and solve;
Volume = 3.14 x 18² x 18
Volume = 18312.5mm³
rewrite in simplest terms : -6u-2(-7u+10)

B.) Side - Angle - Side
C.) Angle - Side - Angle
D.) Angle - Angle - Side
E.) Hypotenuse - Leg
Oh wait I think I know the answer, c.
Answer:
C
Step-by-step explanation:
angle DAB = angle CBA
angle DBA = angle CAB
line AB = line AB
Since we know that the two angles and 1 side are the same on both triangle ADB and BCA, the property is angle side angle
Can u explain to me how to do this :)
Answer:
you have to multiple it
Answer:
x = 35 y = 82
Step-by-step explanation:
all triangles add up to 180
the tick mark shows that 2x = y - 12
2x + 2x + 40 = 180
4x + 40 = 180
4x = 140
x = 35
y - 12 + y - 12 + 40 = 180
2y - 24 + 40 = 180
2y + 16 = 180
2y = 164
y = 82
Check:
40 + 2(35) + (82 - 12) = 180
If c varies diráctly as (1 + 1) and c= 8, when r = 3, calculate the value ofr when c= 20.
(4marks)
c = k(r + 1)
8 = k(3 + 1)
8 = 4k
8/4 = k
2 = k
c=2(r + 1)
When c = 20, then
20 = 2(r + 1)
20 = 2r + 2
20 - 2 = 2r
18 = 2r
18/2 = r
9 = r
Therefore, the value of r is 9 when c is 20.

Solve this equation.
24 + 0.44x = 19 + 1.69x
Answer:
x = 4
Step-by-step explanation:
24 + 0.44x = 19 + 1.69x
24 + 0.44x - 1.69x = 19
-1.25x = 19 - 24
-1.25x = -5
x = 4
Step-by-step explanation:
24 + 0.44x = 19 + 1.69x
24 - 19 = 1.69x - 0.44x
5 = 1.25x
1.25x = 5
x = 5/1.25
= 4
How many 1/8-inch pieces of ribbon can be cut from a piece of ribbon that is 3/4 inch long? *
Answer:
the answer is 6
Step-by-step explanation:
Find what's 1/8 divided by 3/4 in fraction form?
step 1 Address formula, input parameters & values.
Input parameters & values:
1/8 and 3/4
Step 2: change the problem
Remember, always do KCF(Keep,Change,Flip)
First i keep 1/8
1/8 ÷ 3/4
Then I change the sign to multiplication because you need to need to find the answer and simplified it
1/8 x 3/4
Make sure u always flip the other fraction because you are multiplying
1/8 x 4/3
then you do the rest
Step 3:solve
1/8 x 4/3=4/24
Step 4: simplified
24/4=6
Now your answer is 6
Hope it helps :)

Elena's father put $460 into a savings account for her. The account pays 2.5% simple interest each year. If he neither adds nor withdraws
money from the account, how much interest will the account earn after 4 years? Round to the nearest cent.
Answer:
$46
Step-by-step explanation:
Give that Elena's father put $460 into a savings account.
So, the principal amount, P= $ 460
Yearly simple interest , R= 2.5% = 0.025
Time, t = 4 years.
The interest, I, for the principal amount, P, at the rate of R yearly, after t years,
[tex]I= P\times R \times t[/tex]
By using the given values, we have
[tex]I=460\times 0.025 \times 4 = 46[/tex]
Hence, the account will earn $46.
Solve: 2.3 = v + 0.47 v = _____
Answer:
2.3=v+0.47v=
We move all terms to the left:
2.3-(v+0.47v)=0
We add all the numbers together, and all the variables
-(+1.47v)+2.3=0
We get rid of parentheses
-1.47v+2.3=0
We move all terms containing v to the left, all other terms to the right
-1.47v=-2.3
v=-2.3/-1.47
v=1+0.83/1.47
Answer:
[tex]v = 1.564[/tex]
Step-by-step explanation:
[tex]1v + 0.47v = 2.3[/tex]
[tex] = > 1.47v = 2.3[/tex]
[tex] = > v = \frac{2.3}{1.47} = 1.564[/tex]
What’s the combined average of Altuve’s weighted average below:
Friday 3 for 5, Saturday 2 for 4, and Sunday 1 for 3
Answer:
The combined average of Altuve's weighted averages is 1 for 2 or 1/2
Step-by-step explanation:
Combined Average
On Friday, Altuve had 3 out of 5 successes
On Saturday, Altuve had 2 out of 4 successes
On Friday, Altuve had 1 out of 3 successes
The total successes are 3+2+1=6
The total tries are 5+4+3=12
The combined average is:
[tex]\displaystyle \bar x=\frac{6}{12}[/tex]
Simplifying:
[tex]\displaystyle \bar x=\frac{1}{2}[/tex]
The combined average of Altuve's weighted averages is 1 for 2 or 1/2
Find the slope of the following graph and Identify the type of
Slope:
Answer:
undefined
Step-by-step explanation:
Horizontal lines have no slope. The line on the graph is vertical, so we can't really tell what slope it is. But there isn't any run and only rise, therefore the slope is "undefined."

Answer:
[tex]x=\dfrac{-(-1)\pm \sqrt{(-1)^{2}-4(7)(-9)}}{2(7)}[/tex]
Step-by-step explanation:
The quadratic equation is as follows :
[tex]7x^2=9+x[/tex] ...(1)
The solution of a quadratic equation [tex]ax^2+bx+c=0[/tex] is given by :
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]
Equation (1) can also be written as follows :
[tex]7x^2-9-x=0\\\\7x^2-x-9=0[/tex]
Here, a = 7, b = -1 and c = -9
[tex]x=\dfrac{-b+ \sqrt{b^2-4ac} }{2a}, x=\dfrac{-b-\sqrt{b^2-4ac} }{2a}\\\\x=\dfrac{-(-1)+\sqrt{(-1)^{2}-4(7)(-9)}}{2(7)}, \dfrac{-(-1)-\sqrt{(-1)^{2}-4(7)(-9)}}{2(7)}\\\\x=1.20\ s, -1.06\ s[/tex]
Neglecting negative value.
So, it will hit the ground in 1.2 s.

The graph below shows the distance, y, in miles, of a bird from its nest for a certain amount of time, x, in minutes:
Graph titled Distance Vs Time is shown with Time in minutes along the x axis and Distance from Nest in miles along the y axis. The scale on the x axis shows the numbers 0 to 25 at increments of 5, and the scale on the y axis shows the numbers 1 to 8 at increments of 1. A straight line joins the ordered pairs 0, 3 and 5, 4 and 10, 5 and 15, 6 and 20, 7.
Based on the graph, what is the initial value of the graph and what does it represent? (1 point)
a
3 miles per minute; it represents the speed of the bird
b
0.2 mile per minute; it represents the speed of the bird
c
0.2 mile; it represents the original distance of the bird from its nest
d
3 miles; it represents the original distance of the bird from its nest
Answer:
(d).
Step-by-step explanation:
The y-intercept (0, 3) is initial value of graph ⇒ (d). 3 miles; it represents the original distance of the bird from its nest
Answer:
0.2 mile; it represents the original distance of the bird from its nest
