Answer:
The equivalent expression is:
[tex]-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n[/tex]
Step-by-step explanation:
Given the expression
[tex]-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)[/tex]
[tex]\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a[/tex]
[tex]=-16m^2n+25m^2n-7m^2n[/tex]
[tex]\mathrm{Add\:similar\:elements:}\:-16m^2n+25m^2n-7m^2n=2m^2n[/tex]
[tex]=2m^2n[/tex]
Therefore, the equivalent expression is:
[tex]-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n[/tex]

y = x + 3
y=-3
Aolve
Answer:
x=-6
Step-by-step explanation:
y = x + 3 y=-3
-3=x+3
x=-6
Answer:
X = 6 or -6
Step-by-step explanation:
y=-3 so factor that into the problem
so -3 = x + 3 if you move the -3 by adding 3 you get x= 6
but if you move the 3 by subtracting 3 you get x=-6

The sum of two rational number is -3 .If one of them is-15/7 find the other. step explanation
Sum = -3
First no. = -15/7
Second no. = (-3) - (-15/7)
= -3 + 15/7
= -21/7 + 15/7
= (-21 + 15)/7
= -6/7
The second no. is -6/7.
Answer:
[tex]\frac{-6}{7}[/tex]
Step-by-step explanation:
Let the other number be 'x'
[tex]x + \frac{-15}{7} = -3[/tex]
x = [tex]-3 + \frac{15}{7}[/tex]
[tex]= \frac{-3*7}{1*7} +\frac{15}{7}\\\\=\frac{-21}{7}+\frac{15}{7}\\\\= \frac{-21+15}{7}\\\\= \frac{-6}{7}[/tex]

the numerator of a fraction x/y is 2 less than the denominator. If 3 is added to both the numerator and denominator, then the sum of the new fraction and the original fraction is 53/35 find the quadratic equation.
Answer:
Step-by-step explanation:
Fraction :x/y
numerator x = y - 2
Now the fraction can be written as: (y-2)/y
3 is added to both denominator and numerator.
After adding 3, the new fraction = [tex]\frac{y-2 +3 }{y + 3 } = \frac{y+ 1 }{y +3}[/tex]
The sum of the new fraction and the original fraction is 53/35
[tex]\frac{y+1}{y+3} + \frac{y-2}{y} = \frac{53}{35}\\\\\frac{(y+1)*y}{(y+3)*y}+\frac{(y-2)*(y+3)}{y(y+3)}=\frac{53}{35}\\\\\frac{y^{2}+y}{y^{2}+3y}+\frac{y^{2}+y-6}{y^{2}+3y}=\frac{53}{35}\\\\\frac{y^{2}+y+y^{2}+y-6}{y^{2}+3y}=\frac{53}{35}\\\\\frac{2y^{2} + 2y - 6}{y^{2}+3y}=\frac{53}{35}\\\\[/tex]
35*(2y² + 2y - 6) = 53 *(y² + 3y)
35*2y² + 2y * 35 - 6*35 = 53 *y² + 53*3y
70y² + 70y - 210 = 53y² + 159y
70y² + 70y - 210 - 53y² - 159y = 0
70y² - 53y² + 70y - 159y - 210 = 0
17y² - 89y - 210 = 0
Answer:
17y^2 - 89y - 210 = 0
Step-by-step explanation:
Original fraction: x/y
The numerator is 2 les than the denominator, x = y - 2
Original fraction: (y - 2)/y
New fraction:
Add 3 to the numerator and denominator of the original fraction:
(y - 2 + 3)/(y + 3) = (y + 1)/(y + 3)
Add the new fraction and old fraction and get 53/35.
(y - 2)/y + (y + 1)/(y + 3) = 53/35
35y(y + 3)[(y - 2)/y] + 35y(y + 3)[(y + 1)/(y + 3)] = 35y(y + 3)(53/35)
35(y + 3)(y - 2) + 35y(y + 1) = 53(y^2 + 3y)
35(y^2 + y - 6) + 35(y^2 + y) = 53y^2 + 159y
17y^2 - 89y - 210 = 0

What is the area of the obtuse triangle given below? 13. 15
O A. 154 sq. units
B. 48.75 sq. units
C. 97.5 sq. units
D. 195 sq. units
C. 97.5 sq.units
Here, formula to calculate area of obtuse triangle is,
A=1/2 x (base x height)
In the given question let,
base(b)=13
height(h)=15
Then,
A=1/2x(bxh)
A=1/2x(13x15)
A=97.5 sq.units

What is the intermediate step in the form (x + a)2 = b as a result of
completing the square for the following equation?
-3x2 - 36x = 300
Answer:
we need to add a²=6² to both sides of [tex]x^2+12x+6^2=-100+6^2[/tex] in order to rewrite in the form [tex]\left(x\:+\:a\right)^2\:=\:b[/tex].
Step-by-step explanation:
Given the equation
[tex]-3x^2-36x=300[/tex]
First of all, we need to divide both sides by -3 to simplify it
i.e.
[tex]\frac{-3x^2-36x}{-3}=\frac{300}{-3}[/tex]
[tex]x^2+12x=-100[/tex]
In order to rewrite in the form [tex]\left(x\:+\:a\right)^2\:=\:b[/tex], we need to add a²=6² to both sides
[tex]x^2+12x+6^2=-100+6^2[/tex]
so
[tex]\left(x+6\right)^2=-64[/tex]
Therefore, we need to add a²=6² to both sides of [tex]x^2+12x+6^2=-100+6^2[/tex] in order to rewrite in the form [tex]\left(x\:+\:a\right)^2\:=\:b[/tex].

What is always true about a linear pair?
O A. The sum of angle measures is 180°.
B. Each angle measure is the same.
O C. The sum of angle measures is 90°.
D. The sum of angle measures is 360°.
Answer:
O A. The sum of angle measures is 180°.
Step-by-step explanation:
A linear pair of angles are supplementary.
They must add up to 180°.
Linear pairs also would form a straight angle. A straight angle is 180°.

i took the test on edmentum and got it correct
From the histogram graph, it is clear that the graph is skewed left. Anabelle's score should be added to 60 - 70. 5 students scored below 70 on that day.
What is a histogram graph?''A histogram is a graphical representation that organizes a group of data points into user-specified ranges. Similar in appearance to a bar graph, the histogram condenses a data series into an easily interpreted visual by taking many data points and grouping them into logical ranges or bins.''
Given, a histogram that shows the test score results of Ms. Garrison's Algebra class.
1. Data in the histogram is skewed left as the graph is pretty higher on the right hand side and deeper on the left hand side.
2. Anabelle was absent on the day of the test but appeared on the next week. She scored 60. It will be added in the column of 60 - 70.
3. The students who scored less than 70 on that day of exam is = (3 + 2) = 5.
