Answer:
The value of x is 1.
Step-by-step explanation:
You have to move all the x-terms to one side and the unrelated values to other side :
[tex]3.2x - 7.4 = - 7.8x + 3.6[/tex]
[tex]3.2x + 7.8x = 3.6 + 7.4[/tex]
Next, you have to add up :
[tex]11x = 11[/tex]
Lastly, you have to divide it by 11 :
[tex]x = 11 \div 11[/tex]
[tex]x = 1[/tex]

Answer:
x+3=6
x=3 (subtract 3)
3x=9
x=3 (divide 3)
Answer:
4x=20 and x+7=19
Step-by-step explanation:
4x=20. To solve this you divide both sides by 4 and get x=5.
x+7=19. To solve this you subtract both sides by 7 and get x=12

A bag contains 21 red marbles, 4 white marbles, and 3 gray marbles. Do you randomly pick out a marble recorded color and put it back in the bag. You repeat this process 84 times. How many white or gray marbles do you expect to get?
Answer:
28
Step-by-step explanation:
you add 21, 4, and 3 to find the total
then you find how many are white or gray
7/28= 1/3
1/3 times 84
84 times 1 divided by 3
84/3
What is the value for y?
Enter your answer in the box.
Answer:
y = 14
Step-by-step explanation:
The sum of the angles in a triangle add to 180 degrees
50 + 2x+ 5y + 10 = 180
We know that 2x = 50 since they are the base angles of sides that have the same length, they must be the same
50 + 50 + 5y+10 =180
Combine like terms
110 + 5y =180
Subtract 110 from each side
110+5y-110 = 180-110
5y = 70
Divide each side by 5
5y/5 =70/5
y = 14
What is the value of the expression shown when n = 6?
“8 less than the quotient of 42 and a number”
8 minus StartFraction 42 Over n EndFraction; when n = 6 the expression equals 1
StartFraction 42 Over n EndFraction minus 8; when n = 6 the expression equals –1
42 minus 8 n; when n = 6 the expression equals –6
8 n minus 42; when n = 6 the expression equals 6
Answer:
StartFraction 42 Over n EndFraction minus 8; when n = 6 the expression equals –1
Step-by-step explanation:
Let's put the equation into numbers:
“8 less than the quotient of 42 and a number”
= 42/n - 8
Now, substitute 6 into this expression:
42/6 - 8
= 7 - 8
= -1

determine how many different values can arise by inserting one pair of parentheses into the given expression. 3 − 7 − 9 − 5
Answer:
Step-by-step explanation:
(3 - 7) - 9 - 5 = -4 - 9 - 5
= -18
3 - (7 - 9) - 5 = 3 - (-2) - 5
= 3 + 2 - 5
= 5 - 5
= 0
3 - 7 - (9 - 5) = 3 - 7 - 4
= 3 - 11
= -8

The graphed line shown below is y = negative 3 x + 6. On a coordinate plane, a line goes through points (1, 3) and (2, 0). Which equation, when graphed with the given equation, will form a system that has no solution? A)y = 3 x + 6 B)y = negative 3 (x + 6) C)y = negative 3 (x minus 2) D)y = 3 (x minus 2).
Answer:
y = -3 (x + 6) when graphed with the given equation, will form a system that has no solution
Step-by-step explanation:
Given line equation: [tex]y=-3x+6[/tex]
We are supposed to find Which equation, when graphed with the given equation, will form a system that has no solution.
We know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept.
General equation of line = [tex]y=mx+c[/tex]
A)y = 3 x + 6
So, Slope = 3
B)y = -3 (x + 6)
y=-3x-18
So, slope=-3
C)y=-3(x-2)
y=-3x+6
So, Slope = -3
D)y=3(x-2)
Slope =3
So, B has the same slope but different intercept
So,y = -3 (x + 6) when graphed with the given equation, will form a system that has no solution
Answer:
B) y= -3(x+6)

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that five times, the sum of a number and 3 equals 4. the expression can be written as,
5x + 3 = 4
5x = 4 - 3
5x = 1
x = 1 /5 = 0.2

write an equation that can be used to find the value of x.
Answer:
x=29
Step-by-step explanation:
Since you have a 90° angle drawn, all of those angles added together has to equal 90. To solve this you add all of them to get 3x+3=90°. First, subtract the 3 to get the x variable on one side. After this, you get 3x=87. Then, divide by 3 to get x=29. To check this, plug in 29 for x in the equation and add them altogether, it should equal 90° :)

A line passes through the point (9, 4) and has a slope of
4 over 3
Write an equation in slope-intercept form for this line.
Answer: y = 4/3x-9
Step-by-step explanation:
We just need to find the y-intercept, b. Recall that y-intercept form is y=mx+b. Plug in what we have. y=-4, m= 4/3, x=-9.
4= 4/3(9)+b
4=13+b
-9=b
now rewrite the equation with b now. y= 4/3x-9
