Answer:
Step-by-step explanation:
This expression cannot be simplified in any way. 2a and 10b are NOT "like terms." Likewise, the 'c' term has nothing in common with the other two terms.
Find the solution of the system of equations.
15x – 4y = -50
3x – 2y = –16
Answer:
x=-2, y=5. (-2, 5).
Step-by-step explanation:
15x-4y=-50
3x-2y=-16
---------------
15x-4y=-50
-5(3x-2y)=-5(-16)
------------------------
15x-4y=-50
-15x+10y=80
-------------------
6y=30
y=30/6
y=5
3x-2(5)=-16
3x-10=-16
3x=-16+10
3x=-6
x=-6/3
x=-2

Answer:
[tex]\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x} = \frac{x - 6}{4*x}[/tex]
Step-by-step explanation:
We have the expression:
[tex]\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x}[/tex]
The first thing we want to do, is to have the same denominator in both equations, then we need to multiply the first term by (2/2), so the denominator becomes 4*x
We will get:
[tex](\frac{2}{2} )\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x} = \frac{4*x - 4}{4*x} - \frac{3*x + 2}{4*x}[/tex]
Now we can directly add the terms to get:
[tex]\frac{4*x - 4}{4*x} - \frac{3*x + 2}{4*x} = \frac{4*x - 4 - 3*x - 2}{4*x} = \frac{x - 6}{4*x}[/tex]
We can't simplify this anymore

TrueC.
Mean:
(4*5 + 5*3 + 6*2 + 12 + 13*4 + 14*2)/17 = 8.17Median:
6Mean ≠ median, not true
D.
14 - 4 = 109 - 3 = 6, 10 > 6, not trueAnswer:
B
Step-by-step explanation:
Option B is correct because from the data it's visible that all the data are around 6 miles in other words clustered. In Class A half of them are on left and half are on right. Option A is wrong because there are 17 students in class A and 18 students in class B.
Option C is wrong because the mean is 8.2 and the median is 6.
To find mean add up all the miles the students chose and divide by total students (4+4+4+4+4+5+5+5+6+6+12+13+13+13+13+14+14)/17 = 8.2
To find the median line up all the numbers and find the one in middle. It's 6.
Option D is wrong because the range for class A is (14-4)=10
and class B is (9-3)=6. So the range of class A is greater than class B.
To find range maximum value-minimum value

Ashley ate exactly one-third of the peanuts in a dish. Then, Emily ate exactly one-fourth of the remaining peanuts in the dish. Lastly, Isabella ate exactly one-fifth of the remaining peanuts in the dish. What is the least number of peanuts that could be in the dish when Isabella finishes? [Whole peanuts may not be split into smaller parts.]
Answer:
12 peanuts
Step-by-step explanation:
use algebra using the given ratios...and use trial and error to find the total number of peanuts.
multiply that by the final ratio.

Step-by-step explanation:
a movie theater has 15 rows of State each rows have 24. if there where 28 empty seats during one show how many people where there?
Answer:
332
Step-by-step explanation:
To find how many seats there were, multiply the number of rows with the number of seats in each row:
15 (24) = 360
From these total seats, there are 28 empty seats, meaning:
360 - 28 = 332
There were 332 people.
Find the m Angle J if m Angle K = 29° and they are complementary angles.
Answer:
∠J = 61º
Complimentary angles are angles that add up to 90º
∠J = 90º - ∠Kº
= 90º - 29º
=61º
What would be the next step?

y= x+14 , x+ 2y= 36, find x and y and show solution pls
Answer:
Solve the equation for x.
The simplified system is the arbitrary solution of the original system of equations.
Y=x+14
y=18−x2
Reorder 18
and −x2.
y=−x2+18
Y=x+14
Solve the equation for Y.
Y=−2y+50
x=36−2y
Reorder 36
and −2y.
x=−2y+36
Y=−2y+50
Step-by-step explanation:
Step-by-step explanation:
given
[tex]y = x + 14 \\ y - x = 14 \\ - x + y = 14[/tex]
as equation 1
and
[tex]x + 2y = 36[/tex]
as equation 2.
We will now use elimination method to solve simultaneous equations.
We will use equation 1 + equation 2 to eliminate x and solve for y.
[tex] - x + x + y + 2y = 14 + 36 \\ 0 + 3y = 50 \\ 3y = 50 \\ y = 50 \div 3 \\ = \frac{50}{3} \: or \: 16 \frac{2}{3} [/tex]
Now substitute y into equation 1.
[tex]y = x + 14 \\ x + 14 = y \\ x = y - 14 \\ x = 16\frac{2}{3} - 14 \\ = 2 \frac{2}{3} [/tex]
Find the equation of the straight line passing through the point (0, 1)
which is perpendicular to the line
y=-2x + 2
Step-by-step explanation:
y=-2x+2 point(0,1)m1=2=m1×m2=-1
-2×m2=-1=-2m=-1(÷ both sides by -2) M2=1/2 equation 1/2=y-1/x-0 2(y-1)/(x-0)1=2y-2=x-0 y=mx+c=2y=x-0+22y=x+2 (÷all sides by 2)

The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answer:
x = 54
Step-by-step explanation:
All triangle angles add up to 180 so:
x + 36 + 90 = 180
x + 126 = 180
x = 180 - 126
x = 54
