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

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

The fractions will let her find the x-coordinate for point C is 2/5

The formula for calculating the midpoint of coordinates is expressed as:

[tex]M(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Substitute the given coordinate into the formulas:

[tex]M(x,y) = (\frac{3(2)+3(6)}{2+3},\frac{2(2)+3(11)}{2+3}) \\M(x,y) = (\frac{24}{5},\frac{37}{5}) \\M(x,y) = (4.8,7.4)[/tex]

From the calculation, we can see that the fractions will let her find the x-coordinate for point C is 2/5

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]

Answer:

  -77k²m³

Step-by-step explanation:

The variable arrangement is the same for each term, so we simply combine their coefficients:

  k²m³ +22k²m³ -100k²m³ = (1 +22 -100)k²m³ = -77k²m³

Answer:

x1= -4/3 x2= -6/5

Step-by-step explanation:

y= (3x+4)(-5x-6)

now first we replace y with a zero 0

0=(3x+4)(-5x-6)

now we put the 0 to the right

(3x+4)(-5x-6)=0

when the product of factors 0, at least one of the factors is 0 so we do this:

3x+4=0

-5x-6=0

now we solve 3x+4=0 and it leads to:

x=-4/3

after that we do the same for -5x-6=0:

x2=-6/5

Answer and explanation:

The large and small intestine absorb water but the small intestine absorbs more water than the large intestine. Here the small intestine absorbs 9040 ml of water out of 9600ml while the large intestine absorbs the 560ml and 140ml leaves. To calculate percentage that was absorbed by the large intestine(percentage entering the small intestine) and also leaves, we divide the volume that leaves(140ml) by total volume absorbed(560ml) and multiply by 100.

Volume of water entering the small intestine= 9600 ml

Volume of water entering the large intestine= 560 ml

Volume of water leaving the large intestine = 180 ml

Percentage of water entering the small intestine and absorbed by the small intestine= 9600ml - 560 ml= 9040

=9040/9600*100/1= 94.16%

Percentage of water entering the small intestine and absorbed by the volume leaving the large intestine = 560ml-140ml= 140/560*100/1= 25%

Also percentage of water absorbed by large intestine and doesn't leave the large intestine = 420/560*100/1= 75%

a. The percentage of the water entering the small intestine is absorbed by the small intestine is 94.16%

b. The percentage of the water entering the small intestine is absorbed by the Volume leaving the large intestine 140 mL large intestine is 4.375%.

(a)

Volume leaving the small intestine should be

= 9600 - 560

= 9040

Now the percentage should be

[tex]= 9040 \div 9600[/tex]

= 94.16%

(b) Water absorbed by large intestine should be = 560 - 140 = 420 ml

Now the percentage should be

[tex]= 420 \div 9600[/tex]

= 4.375%

Step-by-step explanation:

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.

''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.
