"The model can be used to solve 6×3.27. Select the partial products from the drop-down lists" i have no clue what to do, can someone explain to me?
Answer:
The partial products are:
18 + 1.2 + 0.42
The sum: 19.62
Step-by-step explanation:
This has to do with understanding what place value is.
3 ones = 3 * 1 = 3
6 * 3 ones = 18
2 tenths = [tex] 2 * \frac{1}{10} = 2*0.1 = 0.2 [/tex]
6 * 2 tenths = 1.2
7 hundredths = [tex] 7 * \frac{1}{100} = 7*0.01 = 0.07 [/tex]
6 * 7 hundredths = 0.42
The partial products are:
18 + 1.2 + 0.42
The sum = 19.62

Three step linear equations
8x - 10 = 4x - 30
Answer:
x = -5
Step-by-step explanation:
8x - 10 = 4x - 30
Subtract 4x from each side
8x-4x - 10 = 4x-4x - 30
4x -10 = -30
Add 10 to each side
4x-10+10 = -30+10
4x= -20
Divide by 4
4x/4 = -20/4
x = -5

Use the drawing tool(s) to form the correct answer on the provided graph.
The graph of f(x) = x is shown on the coordinate plane. Function g is a transformation off as shown below.
g(x) =3/4 f(x)
Graph function g on the same coordinate plane.
The graph of the function g(x) = 3/4 f(x) on the same coordinate plane as f(x) = x is attached below.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
To graph the function g(x) = 3/4 f(x) on the same coordinate plane as f(x) = x, we need to perform the transformation of stretching the graph of f(x) by a factor of 3/4.
Determine the scale factor for the transformation. In this case, the scale factor is 3/4.
Starting at the x-intercepts and y-intercepts (if there are any), plot the points on the coordinate plane using the scale factor to stretch or shrink the graph as needed.
For example, the point (0,0) on the graph of f(x) becomes the point (0,0) on the graph of g(x). The point (1,1) on the graph of f(x) becomes the point (1, 3/4) on the graph of g(x).
Connect the plotted points with a smooth curve to obtain the graph of g(x).

Step-by-step explanation:
Zachary purchased a computer for 1100 on a payment plan. 4 months after he purchased the computer, his balance was $755. Five months after he purchased the computer, his balance was $640. What is an equation that models the balance b after m months. What does the slope signify is zacharys equation?
Answer:
Model is
b = 115m + 65
The slope represents the amount of balance offset per month
Step-by-step explanation:
Here, we want to model an equation.
The equation to model will be in the form;
y = mx + c
we have the following points to consider
The points are in the form;
(number of months, balance)
(m , b)
So the points we have are;
(4,755) and (5,640)
So the slope will be ;
(y2 -y1)/(x2-x1) = (755-640)/(5-4) = 115
So the equation will be;
b = am + c
where a is the slope and c is the y intercept
we already have the slope
so equation becomes;
b = 115m + c
let’s get the y-intercept
we can get the y-intercept by any of the points;
That would be; let’s use (5,640)
640 = 5(115) + c
640 = 575 + c
c = 640 -575
c = 65
So the equation of the model is;
b = 115m + 65
The slope represents the balance per month
If m 4 = 48° and m28 = 3x + 9
Answer:
x = 109
Step-by-step explanation:
m4 =48
m =48/4
m = 12
now
m28 = 3x+9
12*28 = 3x + 9
336-9 = 3x
327/3 = x
109 = x

A truck driver has traveled for hours (4, h) south down a highway 50 kilometers per hour (50 km/h) How far as the delivery driver traveled?
Answer:
200 kilometers
Step-by-step explanation:
since the driver goes 50 kilometers at a constant rate for 4 hours, you multiply it by 4, and you get 200.
An easy way to multiply these numbers is to multiply the 4 and 5, which equals 20, then add the extra zero from the 50.

Answer:
The angle across the given measurements are the same. So there will be a 27 degrees across from the other 27 degrees. The straight line is 180 degrees, so do 180-27=153. The means the other 2 angles are 153 degrees. The other one is the same, but with different measurements. 180-35=145
Step-by-step explanation:
Let the angle adjacent to ∠27° be x .
[tex]∠x + 27 = 180° \: ( \: linear \: pair \: )[/tex]
[tex]x = 180 - 27 \\ ∠x = 153°[/tex]
Let the angle opposite to ∠27° be y .
[tex]∠y = ∠27° \: ( \: vertically \: opposite \: angles \: )[/tex]
Let the angle adjacent to ∠y ( 27°) be w .
[tex]w + ∠27° = 180° \: ( \: linear \: pair \: ) \\ w = 180 - 27 \\ ∠w = 153°[/tex]
Let the angle opposite to ∠35° be p .
[tex]∠p = ∠35° \: ( \: vertically \: opposite \: angles \: )[/tex]
Let the angle adjacent to ∠35° be a .
[tex]∠a + 35° =180 ° \: ( linear \: pair ) \\ a = 180 - 35 \\ ∠a = 145°[/tex]
Let the angle opposite to ∠35° be t .
[tex]∠t = 35° \: ( \: vertically \: opposite \: angles \: )[/tex]
Let the angle opposite to ∠145° be o .
[tex]∠o \: = 145° \: ( \: vertically \: opposite \: angles \: )[/tex]
– 3х + 10 = 2
— 3х + Зу = 9
Answer: A! x=-1 2/5, y= 1 3/5
Step-by-step explanation:
First put -3x+3y=9 into slope-intercept form(y=mx+b)
3y=-3x+9
then solve for y
y=-1x+3
enter your y-intercept into the equation below..
2x-7(-1x+3)=-14
2x+7x-21=-14
2x+7x=-14+21(when changing sides it changes signs that's why 21 is now a positive)
2x-7x=7
-5x=7 divide -5 into 7
7/5
x=-1 and 2/5
then input x back into the first equation
-3(7/-5)+3y=9
21/5+3y=9
3y=9-21/5
3y=24/5
divide 3 into 24/5
=24/15=1 and 9/15 reduce it anddd
y=1 and 3/5
