Answer:
[tex]z=-317[/tex]
Step-by-step explanation:
1) Simplify 45 × 28 to 1260.
[tex]1260=19*83+z[/tex]
2) Simplify 19 × 83 to 1577.
[tex]1260=1577+z[/tex]
3) Subtract 1577 from both sides.
[tex]1260-1577=z[/tex]
4) Simplify 1260 - 1577 to −317.
[tex]-317=z[/tex]
5) Switch sides.
[tex]z=-317[/tex]
Therefor, the answer is z = -317.

Help please what is the area in square units
Answer:
I think it might be 23. sorry if it is wrong :(
23 cubes
My answer is assuming the question uses the squares as units.
There are 20 whole squares
Two half squares= 1 square
There are 2 sets of 2 square spaces split from one corner to the opposite. They look to be split the same way, and to also be opposite halves of each other, like the two half squares mentioned before. However, this equals two squares, because 4 in total are split equally.

(fractions 5th grade) 2/4 + 3/4=?
Answer:
5/4
Step-by-step explanation:
They are like fractions.
So, [tex]\frac{2}{4} + \frac{3}{4}[/tex] can be written as [tex]\frac{2+3}{4}[/tex]
Thus the answer is [tex]\frac{5}{4}[/tex].
4. Roger was growing plants for his science project. He measured the plants every day.
He found that one plant grew 1/3 of an inch every day for 10 days. How many inches
did the plant grow in those 10 days?
Answer:
the answer could be 10/3 and decimal form is 3.3 and mixed form is 3 1/3 (i hope this helps sorry if I'm wrong!)
Step-by-step explanation:
Answer: 1/3 of an inch is 0.3 and 0.3 x 10 = 3. it did grow probably
Step-by-step explanation:
If 5b = 6a + 16 and 9a = 7b - 20, then what are the values of a and b?
9514 1404 393
Answer:
(a, b) = (4, 8)
Step-by-step explanation:
Writing both equations in general form, we have ...
6a -5b +16 = 0
9a -7b +20 = 0
__
We can make a little array of the numbers in the equations:
[tex]\left[\begin{array}{cccc}6&-5&16&6\\9&-7&20&9\end{array}\right][/tex]
Note that the first column is repeated at the end.
Now, we can "cross multiply" and form the differences of products in adjacent columns:
d1 = (6)(-7) -(9)(-5) = 3 . . . . . . left 2 columns
d2 = (-5)(20) -(-7)(16) = 12 . . . . . middle 2 columns
d3 = (16)(9) -(20)(6) = 24 . . . . . right 2 columns
Then the solutions to these equations are the solutions to ...
1/d1 = a/d2 = b/d3
a = d2/d1 = 12/3 = 4
b = d3/d1 = 24/3 = 8
The values of a and b are 4 and 8, respectively.

Additional Comment
There are a number of ways to solve linear equations. This is similar to what you would get by doing "elimination". It is also similar to Cramer's Rule and Vedic math techniques. The number of math operations is about the same*. Once you learn the technique, it is fairly fast and requires no decision-making. My other favorite method is using a graphing calculator.
__
* This method uses 6 multiplications, 3 subtractions, 2 divisions. In the general case of "elimination", where the coefficients are not "nice" (as here), you would perform 7 multiplications, 4 subtractions and 2 divisions. This method is less work when the coefficients don't cancel easily.
The area of the Pacific Ocean is about 6.0061 x 10^7 square miles. The area of the Southern Ocean is about 7.8483 x 10^6 square miles. Approximately how many times larger is the area of the Pacific Ocean than that of the Southern Ocean?
Answer:
7.653 larger
Step-by-step explanation:
Pacific area/Southern area = (6.0061) * 10^7 / (7.8483) * 10^6
= 6.0061/ 7.8483 * 10^7/10^6
= 0.7653 * 10^(7-6)
= 0.7653 * 10^1
= 0.7653 * 10
= 7.653
Compared to the Southern Ocean, the Pacific Ocean is about 7.653 times larger.

What is the volume of a cube with a side length of 2/3 cm? *
What are the possible values for m and n
Answer:
m=4
n=-6
The above is just a possible value you can come up with your own :D.
See below for an explanation.
Step-by-step explanation:
Here you are going to really know the exponent rules. But in jest, you basically need to know that m+n=-2 due to exponent rules.
So?
An example would be
m=4
n=-6
Why?
Because 4-6=-2!
Find the area of a rectangle with a width of 2/3 inches and a height of 8 inches. (*just put the number, square inches)
Answer:
[tex]\frac{16}{3}in^2[/tex]
Step-by-step explanation:
the area of a rectangle is the multiplication of dimensions.
A = (2/3)in * 8in = (16/3)in^2

Answer:
The two are NOT THE SAME function.
Step-by-step explanation:
The linear function that is expressed as the equation y = -x + 3, is given in the slope-intercept form, y = mx + b, where
m = slope = -1
b = y-intercept = 3
To know if this function is the same with function expressed in the table of values, let's find the slope (m) and y-intercept (b) of the function represented as a table.
✔️Slope = change in y / change in x = ∆y/∆x
Using two pairs of values form the table, say, (-4, 1) and (-2, -1):
Slope (m) = (-1 - 1) / (-2 - (-4)) = -2/2 = -1
slope (m) = -1
To find b, substitute (x, y) = (-4, 1) and m = -1 into y = mx + b,
Thus:
1 = (-1)(-4) + b
1 = 4 + b
1 - 4 = b
-3 = b
b = -3
Write the equation for the table of values by substituting b = -3 and m = -1 into y = mx + b
Thus:
y = (-1)x + (-3)
y = -x - 3
As you can see, the equation of the function of the table of values is different from the equation of the function that was stated earlier.
Therefore, we can conclude that the two functions are not the same function expressed in different ways.

Consider the triangle below. One of the side lengths is unknown.
Find the length of the unknown side in this triangle, rounding your answer to two decimal places (if necessary).
The other side would be 15 meters.
Answer:
b = 13.27
Step-by-step explanation:
b^2 + 7^2 = 15^2
b^2 + 49 = 225
b^2 = 176
b = sqrt(176)
b = sqrt(16 * 11)
b = 4sqrt(11)
b = 13.27
