Answer:
x= 20
Step-by-step explanation:
Step 1- Distribute into the parenthesis.
3x-1(3)-8= 1(4)+4x+5
Step 2- Multiply
3x-3-8= 4+4x+5
Step 3- Add.
3x-3-8= 4x+9
Step 4- Subtract 3x to both sides to move the variable to one side.
3x-11= 4x+9
-3x -3x
Step 5- Subtract 9 to both sides.
-11= 1x+9
-9 -9
-20= x
Exchange the signs.
20= x
Answer:
x = -20
Step-by-step explanation:
3(x - 1) - 8 = 4(1+x) + 5
3x - 3 -8 = 4 + 4x + 5
3x - 11 = 9 + 4x
-x = 20
x = -20
how do i solve for equations that have 2 variables
Answer:
To solve for an equation with two variables, substitute a zero(0) into the other variable and find one variable.
Step-by-step explanation:
To solve for an equation with two variables, substitute a zero(0) into the other variable and find one variable.
Simple Example:
3x+3y=12
Substitute 0 as y,
3x+0=12
3x=12
12/3=4
x=4
Now substitute 4 into the main equation,
3(4)+3y=12
12+3y=12
-12 -12
3y=0
0/3=0
y=0
So the answer is
3(4)+3(0)=12
12=12

I don't know this one bruh
Hey there!
ANSWER: [tex]f=-16[/tex]EXPLANATION:[tex]\frac{f}{4}-5=-9[/tex]
Simplify both sides and you get:
[tex]\frac{1}{4}f-5=9[/tex]
Now add 5 to both sides and you get:
[tex]\frac{1}{4}f=-4[/tex]
Now you have to multiply both sides and you get:

Use the functions f(x)=2x and g(x)= x^2+1 to find the value of each expression.
7. f(3)+g(4) 8. g(3)+f(4)
Answer:
First, you learned (back in grammar school) that you can add, subtract, multiply, and divide numbers. Then you learned that you can add, subtract, multiply, and divide polynomials. Now you will learn that you can also add, subtract, multiply, and divide functions. Performing these operations on functions is no more complicated than the notation itself. For instance, when they give you the formulas for two functions and tell you to find the sum, all they're telling you to do is add the two formulas. There's nothing more to this topic than that, other than perhaps some simplification of the expressions involved.
Step-by-step explanation:
To find the answers, all I have to do is apply the operations (plus, minus, times, and divide) that they tell me to, in the order that they tell me to.
(f + g)(x) = f (x) + g(x)
= [3x + 2] + [4 – 5x]
= 3x + 2 + 4 – 5x
= 3x – 5x + 2 + 4
= –2x + 6
(f – g)(x) = f (x) – g(x)
= [3x + 2] – [4 – 5x]
= 3x + 2 – 4 + 5x
= 3x + 5x + 2 – 4
= 8x – 2
(f × g)(x) = [f (x)][g(x)]
= (3x + 2)(4 – 5x)
= 12x + 8 – 15x2 – 10x
= –15x2 + 2x + 8
\left(\small{\dfrac{f}{g}}\right)(x) = \small{\dfrac{f(x)}{g(x)}}(

y−5=3(y−3) [tex]y−5=3(y−3)[/tex]
Steps to solve:
y - 5 = 3(y - 3)
~Distribute right side
y - 5 = 3y - 9
~Add 5 to both sides
y = 3y - 4
~Subtract 3y to both sides
-2y = -4
~Divide -2 to both sides
y = 2

Explain how to check if a point is on a line. Please I need this right knowWrite a sentence using an adverb clause illustrating the following usage. contrast
Answer:
Sample Answer: Write the equation using slope and y-intercept in slope-intercept form, y = –275x + 3500. Then, substitute the x and y values of the point into the equation, 1850 = –275(6) + 3500. Simplify to see if both sides are equivalent. Yes, the instructor is correct because both sides are equivalent.

Solye for x
7(x + 1) = 21
Answer:
x = 2
Step-by-step explanation:
Given
7(x + 1) = 21 ( divide both sides by 7 )
x + 1 = 3 ( subtract 1 from both sides )
x = 2
Answer:
x=2
Step-by-step explanation:
7×(x +1)=21
7x +7 =21
7x =21 - 7
7x =14
x=14 :7
x=2
7 ×(2 +1)=21
7 ×3 =21

what is 75.3% of 1394
Answer:
1049.682 is 75.3% of 1394 or as a fraction is 1049 341/500
Step-by-step explanation:
1394/x=100/75.3
(1394/x)*x=(100/75.3)*x - we multiply both sides of the equation by x
1394=1.32802124834*x - we divide both sides of the equation by (1.32802124834) to get x
1394/1.32802124834=x
1049.682=x
x=1049.682
Answer:

Tanya is 6 times younger than her great-grandfather. If a zero is placed between the digits of her age, it will read as the age of her great-grandfather. How old is Tanya?
Answer:
Tanya is 18 years old.
Step-by-step explanation:
In order to determine this, we assume the following
x = tens digit of the age of Tanya, and also the hundreds digit of Tanya's great-grandfather age
y = units digit of the age of Tanya, and also the units digit of Tanya's great-grandfather age
Therefore, we have:
10x + y = (1 / 6) * (100x + y)
Multiply both sides by 6, we have:
[10x + y] * 6 = [(1 / 6) * (100x + y)] * 6
60x + 6y = 100x + y
Collect the like terms, we have:
6y - y = 100x - 60x
5y = 40x
Divide through by 5, we have:
y = 8x
That is,
8x = y
Note that x and y has to be single digits. This can only be obtained only when x = 1 and y = 8. And given how x and y is defined above, we have:
The age of Tanya = 18
This can be verified as follows:
18 = 108 / 6
18 * 6 = 108
108 = 108
Therefore, Tanya is 18 years old.
