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.
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]

Step-by-step explanation:
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

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 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)

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
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

When y varies proportionally with x, what is k when x = 50 and y = 375?
Answer:
x/375=50/100 if its a percent
Step-by-step explanation:
simplify the expression
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

17 vs 18, not trueB.
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
