What is the quotient of −112÷2 1/3 ?
Answers
Answer:
-48
Step-by-step explanation:
−112÷2 1/3 needs to be rewritten as -112 / (7/3), where 7/3 is the improper fraction version of 2 1/3.
Then we have
-112
---------
7/3
Recall that division by a fraction is equivalent to multiplication by the reciprocal of the fraction; thus, the above expression becomes
-112 * 3
-----------
7
This, in turn, can be reduced through division to -16*3, which equals -48.

To make it easier to understand, consider the exponent of a number with no decimals, with 1 decimal and with 2 decimals:
No decimals - the exponent has no decimals1 decimal - put the number as (a*10⁻¹)ⁿ = aⁿ10⁻ⁿ, there will be n decimals2 decimals - similar to above- (a*10⁻²)ⁿ = aⁿ10⁻²ⁿ, there will be 2n decimalsSince our given number is (0.23)⁹, with 2 decimal places, its exponent will have 2*9 = 18 decimals.
bChoose the equation that represents the graph.
Oy = x - 3
Oy = -x + 3
Oy = -x-3
Oy = x + 3
Answers
The graph illustrates a linear function, because the graph is a straight line
The equation of the graph is (d) y = x +3
The points on the line are:
[tex](x_1,y_1) = (-3,0)[/tex]
[tex](x_2,y_2) = (0,3)[/tex]
First, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute values for x1, x2, y1 and y2
[tex]m = \frac{3-0}{0--3}[/tex]
Simplify
[tex]m = \frac{3}{3}[/tex]
Divide
[tex]m = 1[/tex]
The equation of the line is then calculated using the following formula:
[tex]y = m(x - x_1) + y_1[/tex]
Substitute values for m, x1 and y1
[tex]y = 1(x - -3) + 0[/tex]
Simplify
[tex]y = 1(x +3)[/tex]
Open bracket
[tex]y = x +3[/tex]
Hence, the equation of the graph is (d) y = x +3

Determine if (0,-5) is a
solution to the equation
y = -5x
Answers
Plug (0,-5) into the equation -
-5 = -5(0)
-5 times 0 is 0
-5 = 0
(0,-5) is NOT a solution to the equation.
Good luck!
Answer:
No, it is not the solution to the equation.
Step-by-step explanation:
(0, -5)
y = -5x
So we have to plug in the values for x and y. 0 is our x value and -5 is our y value.
-5 = -5(0)
-5 = 0
Therefore, (0, -5) is not a solution to the equation

Internal angles of a triangle = 180 degrees
So knowing this we can form the following equation
(x + 26) + (x + 14) + (4x - 10) = 180
Simplify
(x + x + 4x) + (26 + 14 - 10) = 180

6x = 150
x = 25

Line segment JK has endpoints J(2,-3) and K(-4,6). what are the coordinates of the midpoint of JK
Answers
Answer:
The midpoint is (-1, 1.5)
Step-by-step explanation:
To find the x coordinate of the midpoint, average the x coordinates of the endpoints
(2+-4)/2 = -2/2 = -1
To find the y coordinate of the midpoint, average the y coordinates of the endpoints
(-3+6)/2 = 3/2 = 1.5

The answer is p= 2 and 1/3
Step-by-step explanation:
This answer can be found using the order of operations to solve for p.
Start by distributing 2/3 by (5p-6)

A wire 22 cm long is cut into two pieces. The longer piece is 4 cm longer than the shorter piece. Find the length of the shorter piece of wire
Answers
Explanation: L = longer piece S = shorter piece
L + S = 22
L = 4 + S
S + S + 4 = 22
-4 -4
S + S = 18
S = 18/2 = 9 cm
L = 4 + S —> 4 + 9 = 13 cm
To confirm:
13 cm + 9 cm = 22 cm
Therefore, the shorter piece is 9 cm.

y = -1/5x - 10
Step-by-step explanation:
Pick any two points on the line.
(0,-10) and (50,-20)
find the slope by using m = y2-y1/x2 - x1(rise over run)
m = -20-(-10) / 50 - 0
m = -10/50 = -1/5 -- this is your slope
slope intercept form is y = mx + b, but we need to find your b, which is your y intercept. you find this by asking yourself, what is the y coordinate when x = 0? It is -10.
so now you have all the points you need.
y = mx + b
y = -1/5x - 10

Answer:
27/4 or 6 3/4
Step-by-step explanation:
Change all mixed numbers into improper fractions
2 1/9 = 19/9
6 1/4 = 25/4
19/9 ÷ 2/3 - 25/4 x 2/5
dividing fractions you can multiply and use reciprocal of the fraction (means you switch the top and bottom numbers)
19/9 x 3/2 - 25/4 x 2/5
you can reduce the top and bottom numbers to make them smaller by dividing. find a common number to divide them by, you can cross out the numbers and just put the new equation below
19/3 x 1/2 - 5/4 x 2/1
multiply across the fractions first PEMDAS, then subtract
19/6 - 10/4 (multiply by 2 and 3 respectively to get both bottom numbers the same, multiply by the same number on top)
57/12 - 30/12 = 27/12
1/5 x 1/3 + 2/5 x 2/3
1/15 + 4/15 = 5/15 or 1/3
27/12 / 1/3
you can multiply the fractions and flip the top and bottom numbers of 1/3
27/12 x 3/1
reduce 12 and 3
27/4 x 1/1 = 27/4 or 6 3/4
